E. P. VAN DUZEE. 



Uhler. This is a pale species, differing from all our other species, 

 except Uhleri, in its regularly dotted elytra. In the form of the 

 last ventral segment of the female it corresponds with humidus, but 

 the lateral angles are less prominent. The male is unknown to me. 



12. Flilepsiiis apertus n. sp. 



Form of incisus nearly, vertex proportionately longer. Elytra white, rather 

 sparsely reticulated aud marked with two ill-defined fulvous bands and some- 

 times a basal cloud. Length 6.5 mm. 



Head as wide as the pronotum 'J, . or a little wider J . Vertex nearly one-third 

 longer at the middle than next the eye, disc feebly depressed near the hind 

 margin, apex obtuse, anterior edge subacute. Pronotum hardly more than twice 

 the leugth of the vertex, discal pits scattering, wrinkles distinct; scutellum 

 four fifths the length of the pronotum, apical striae distinct aud irregular in the 

 % , or almost obsolete, 9- Length and breadth of the front subequal, width at 

 apex oue-tliird that at the ocelli ; clypeus rectangular, width three-fourths the 

 length, in the 9 ^ little widened apically : cheeks as in irroratus. 



Genital characters. — Male: Valve about one-fifth louger than the last ventral 

 .segment, triangular, apex truncated ; plates broad, basally the sides are oblique 

 and nearly rectilinear, on the apical one-fourth suhparallel, to the rounded di- 

 vergent tips ; marginal pile and submarginal row of stout spines becoming obso- 

 lete before the apex. Female: Ultimate ventral segment (PI. I, fig. 12) nearly 

 square, broadly excavated on the middle nearly to the base, the sides of the sinus 

 waved, internal angles of the lateral lobes produced in a short acute tooth either 

 side of the broad sinus, the outer angles rounded. Pygofers moderately exceeded 

 by the oviduct, armed toward their apex with numerous spines. 



General color paler than in incisus. Head and scutellum tinged with fulvous; 

 anterior edge of the verte.x with its apical field white, marked with a brown 

 cloud either side of the middle line. Elytra ivory white; a fulvous cloud 

 crosses the middle, another occupies the antiapical areoles, and sometimes there 

 is a third on the base ; reticulations few on the white areas, finer and more nu- 

 merous on the fulvous clouds. Wings faintly smoky, iridescent, nervures strong 

 brown. Legs and abdomen showing the normal markings; sinus of the last 

 ventral segment of the female edged with black. 



Described from one female and three male examples. One re- 

 ceived from M. Provancher, taken near Quebec, the others taken by 

 myself near Muskoka Lake, Ontario, in July, 1888. 



This species is readily distinguished from irroratus, trinicatus and 

 incisus, its nearest allies, by the longer vertex, whiter, more or less 

 distinctly banded elytra, and the characters of the genitalia. 



13. Plilepsius huiniflus n. sp. 



Large, form broad and stout; vertex well produced and depressed, anterior 

 edge thin ; elytra closely and finely reticulated. Length 7 — 7.5 mm. 



Vertex at least one-half longer at the middle than next the eye, apex obtusely 

 angled, anterior edge acute ; front one-fourth longer than broad, sutures arcuated 

 above the antennae, below straight; clypeus moderately widened toward the 

 truncated apex ; outer angles of the cheeks well rounded. Pronotum twice the
