putictiiriMl, ventral segments more finely ]innctiire(l ; femora feebly cUivate, in- 

 fuscate about the middle, tibise slender, a little wider towards the ajiex, the ante- 

 rior somewhat curved, middle and posterior nearly straight, tarsi slender, third 

 joint not broadly bilobed. the fourth shorter than the two preceding joints com- 

 bined, claws simple, slightly divergent. Length 2.0 mm. ; 0.08 inch. 



% . Second ventral .segment with a round and rather deej) fovea, bordered on 

 its anterior circumference by an elevated margin. Last ventral with an ill-de- 

 tined, triangular and somewhat spongy ^pace. 



Hub. — Detroit, Mich. 



A single specimen in Dr. Horn's coll. The fovea on the .second 

 ventral is very renuirkal)le. Difiei-s from the preceding species by 

 its smaller size, much smaller elytral asperities and shorter fourth 

 tarsal joint ; from the next species, with which it agrees in size, by 

 the absence of the prothoracic sulcus and the presence of the elytral 

 asperities. 



P. NquaiiiO!«ll»« Lee. PI. xiv. fig. .37«.— Oval, jiitehy l)Iack, antenme and 

 legs rufo-piceous, above densely clothed with small, dark gray scales, having a 

 feeble brassy lustre, indistinctly mottled with larger, graj'ish white scales, under- 

 side not densely clothed with grayish white scales. Beak stout, cylindrical, fully 

 as long as the head and separated from the latter by an ill-defined, curved line 

 in front of the eyes, very little widened towards the ai)ex, densely and rather 

 finely punctured, squamose ; antennae moderate, inserted two-fifths from the 

 apex ( % ), second joint of funide a trifle shorter than the first and distinctly lon- 

 ger than the third, outer joints short, club rather large, elongate. Eyes moder- 

 ately convex. Head densely punctured, squamose. scarcely concave between the 

 eyes, a median vitta and an ill-defined spot before each eye of white scales; pro- 

 thorax nearly twice as wide as long, one-third wider at the base than at the apex, 

 feebly rounded on the sides and transversely impressed behind the anterior mar- 

 gin, base very feebly emarginate each side, lateral tubercles acute, anterior margin 

 with two very acute, distant cusps, a little smaller than the lateral tubercles and 

 with the margin between them emarginate, dorsal channel wide, distinct, ending 

 into a triangular fossa anteriorly; surface densely and finely punctured, sides 

 and doi-sal sulcus clothed with white scales; scutel very small, scarcely visible. 

 Elytra one-third wider at the base than the prothorax, a little longer than wide, 

 moderately narrowed behind, humeri rather prominent, strife not deeply im- 

 pressed, punctures small, rather distant, intersjjaces flattened, finely punctured, 

 without asi)erities, the pale scales are condensed in transverse fascias and along 

 the suture, a short line behind the scutelluni of dark gray, velvety scales; py- 

 gidium finely and densely punctured, underside not coarsely punctured. Legs 

 and tarsi slender, thirtl joint of the latter not broadly bilobed, last joint shorter 

 than the two preceding joints. Length 2.0 mm. ; 0.08 inch. 



%. Liist ventral segment with a large, (juadrilateral fovea, fully occupying 

 the middle third of the segment and limited each side by a ridge.
