taken on the occasion of a meeting of ’the

College Field Club.This insect has been compared by Mr. Fox

with Cresson’s types, and as he remarks, itresembles P. montaus from Nevada, butdiffers in the entire bands of the abdomen.Bombomelecta alfredi, n. sp.--’, about

3 mm. long, black, with dirty white or

pale cinereous pubescence. Head broad,clypeus greatly produced; face, cheeks,and occiput densely clothed with longwhite hairs, mixed with black on cheeksbeneath, and on clypeus a purer white, silkyand shining. Antennae reaching a littlebeyond tegulae, black, truncate at tips,second joint of flagellum longer than first.Thorax with large punctures visible on

dorsum, but mostly so covered with longdirty-white pubescence that the surfacecannot be seen. Among the hairs, thetwo short but distinct scutellar spines arevisible. The pubescence on the pleura is

very long and dense. Legs black, with

sparse black pubescence, mixed with whit-ish. The anterior and middle femora beloware fi’inged with white hairs but the pos-terior femora have no such fringe. Themiddle tibiae show short white pubescencewithout. The first joint of posterior tarsibears in addition to the short pubescence,six long black hairs. The posterior tibiaeare broadly dilated to their truncate endsand the innermost spine is longest and

slightly curved. The first jointof posteriortarsi is distinctly shorter than the tibia.

Tegulae pitch-black, shining, microscopi-cally reticulate. Wings smoky-hyaline,the apical margin broadly smoky. Nervuresdark brown. Second submarginal cellnarrowing to a point at marginal. Vena-tion otherwise as in B. tkoracica vat.

fulvida.Abdomen black with minute punctures,

first four segments each with. a transverselyelongate patch of dirty-vhite pubescenceon each. side, these patches successivelysmaller fi’om the first. Tip of abdomenemarginate.Hab.Las Cruces, N. M., on a young

cottonwood tree by the Agricultural College,April tT, t895. (Alfred Holt.) By thecolor and arrangement of the pubescence,this is clearly distinct. The only othertombomelecta found in the Mesilla Valleyis B. h oracica var. fulvida, Cr., on Lycium(Jessie Casad).

DORYPHORA (MYCOCORYNA)EOLATA STAL.

This insect was found in great numbers on

a bush with linear leaves, Aug. 29, i894, at SanAugustine, N.M. Mr. Wickham, who kindlyidentified it for me, found it on apparentlythe same plant in the Pinal Mts., Arizona.The eggs are laid on the leaves, about a

dozen together, in two rows, touching,obliquely extending upwards they are cylin-dric,d, 2 mm. long, chrome yellow. Onebatch of about 25 eggs found.Larva shaped as usual in the genus, 7 mm.

long in contraction, jerking fl’om side to side

when disturbed. Head pale yellow, withtwo elongate-pyriform, upwardly-converging,black marks on upper part of fice. Body yel-lowish-white with a lateral series of squarishblack marks, nearly forming a band a narrow

dorsal black stripe, wanting on first segment,and also wanting on second (concealed)segment. The junction of the segmentsmarked by black lines. Last two segmentsmostly black above. Legs mostly black.The imago has the thorax green, and the

elytra ochreous marked with black.T. 29. A. CklL
