74 E. p. VAN DUZEE. 



This is a larger, broader, darker colored species than irroratiis, 

 from which it may be distinguished by its short, depressed, sharp- 

 edged vertex, the form of the clypeus and lone, and especially by 

 its very distinct genital characters.

Cat. Honiop, iii, p. 894. 

 Phlepsius fulvidorsum Van Duzee, Psyche, v, p. 390, 1890. 



Form of P. humidus nearly. Head, pronotuni and scutelhim soiled yellow, 

 obscurely marked with fulvous-browu. Elytra white, faintly clouded with ful- 

 vous patches and rather irregularly inscribed. Length 6 — 7 mm. 



Vertex nearly flat, tip slightly reflexed, length next the eye hardly more than 

 one-half that on the median line, anterior edge subacute: ocelli large, placed 

 rather distant from the eyes. Pronotum about twice the length of the vertex, 

 hind edge a little more concave than in irroratus. pits numerous and conspicuous, 

 especially across the middle of the disc, wrinkles obscure, surface minutely sha- 

 greened posteriorly; scutellnm a little shorter than the pronotum, apical striae 

 obscure; front about one-fifth longer than broad, width at apex one-fourth that 

 at the ocelli; clypeus quadrangular, but slightly widened apically, its sutures 

 straight; outer angle of the cheeks rounded. 



Genital characters. — Male : Valve shorter than the ultimate ventral segment 

 broad-triangular, apex rounded ; plates more than twice the length of the' valve, 

 long-triangular, sides feebly concave, base moderately gibbous, apex obtuse, 

 suture straight, submargin with about eight long stout spines. Female: Last 

 ventral segment (PI. I, fig. 10) long, apical edge rather deeply excavated either 

 side of the small median notch, outer angles well produced and rounded, me- 

 dian line impressed nearly to the base. Pygofers rather narrow, hardly ex- 

 ceeded by the oviduct, the stout apical spines tipped with black. 



Color: Head, pronotum, scutellum, commissural uervure of the elytra, con- 

 nexivum. and all beneath soiled whitish yellow : vertex and pronotum obscurely 

 irrorate with fulvous-brown ; face pale brown, at least superiorly, dotted with 

 pale yellow, front with three basal dots and about four lateral arcs pale ; clypeus 

 usually pale, with a median brown line ; narrow margins of the ventral segments 

 brown, the disc of the venter clouded with the same color with a central pale 

 line. Last ventral segment of the female pale, with a black marginal lunule 

 bounding the lateral sinuses. Legs with the usual marks clearly defined. Eyes 

 mottled. Elytra ivory-white, varied with pale fulvous-brown, the fulvous areas 

 arranged somewhat obliquely ; reticulations rather coarse, costal spots not con- 

 spicuous. Wings smoky, with strong brown nervures. 



This species has proved quite a \mzz\e to me. It occurs in two 

 forms which I cannot consider specifically distinct. Of the form 

 described above, which 1 believe to be the one described by Dr. 

 Fitch, as it agrees in every particular with his short diagnoses, I 

 have seen but three examples, one male and two females, taken by 

 me on hemlock bushes at Golden, N. Y., about the first of August. 

 The other form is smaller, darker in color, and has a shorter vertex ;
