CUCUJID,E 133 



lively much smaller head and prothorax when compared with the 

 broad elytra. The Calif ornian pubescens Csy., differs from allied 

 species in its large and stout basal joint of the antennae; quadratus 

 Csy., is much narrower and has unusually long elytra when compared 

 with the head and prothorax. The following species are hitherto 

 undescribed : 



Cryptolestes disseptus n. sp.- Broad, oblong, not parallel, very de- 

 pressed, rather dull in lustre and pale brown in color throughout; pu- 

 bescence short but close and distinct; punctures small but deep and very 

 close-set throughout anteriorly, not quite so fine and feebler though close- 

 set and confused on the elytra; head much narrower than the prothorax, 

 the basal constriction extending across the dorsal surface chagrined but 

 impunctate, the sides straight and converging in basal two-thirds, then 

 constricted; eyes rather large and prominent, before -the base, the tem- 

 pora converging; antennae fully as long as the elytra, with a loose but 

 evident 3-jointed club, the basal joint not very stout, oboval, not as 

 long as the next two, the next three equal in length and slightly shorter 

 than five to seven, eighth a little shorter than the seventh; prothorax two- 

 fifths wider than long, the base slightly narrower than the apex, the sides 

 slightly arcuate and feebly quadrisinuate as a rule, the cusp points very 

 feeble, all the angles minutely dentiform; surface nearly flat, becoming 

 concave between the strong sublateral carinules and the sides; scutellum 

 fully twice as wide as long, broadly angulate at apex; elytra broad and 

 parallel, a third wider than the prothorax and fully three times as long, 

 the sides feebly arcuate, rounding more in apical third; surface flat, with 

 two discal carinse and a strong sublateral keel, between which and the 

 sides the surface slopes steeply and concavely; sutural line feebly ele- 

 vated, flat; under surface rather dull; last four ventrals equal. Length 

 (cf) 1.7-1.9 mm.; width 0.7-0.78 mm. Texas (Columbus), Schwarz. 



Evidently allied to the Californian horni Csy., but with the undu- 

 lations at the sides of the prothorax very shallow and feeble and the 

 carinulate sides of the head, above the somewhat larger eyes, straight 

 for a much longer distance from the base. The anterior coxal 

 cavities seem to be closed behind much more narrowly than in 

 ferrugineus, and, in this and several other ways, horni and disseptus 

 form a distinct subgeneric group of Cryptolestes. Both of the speci- 

 mens at hand seem to be males.* 



* Since the above was written, I have received from the Fuchs collection a male of 

 horni, taken in Ventura Co., California. The original description and figure of horni 

 were evidently drawn from the female, the antennae being notably short, and perhaps 

 in that sex the undulations at the sides of the prothorax are somewhat stronger than in 

 the male. At any rate, these undulations in this Ventura exponent of horni are no 

 more conspicuous than in disseptus, but, as a species, it differs from the latter in its 

 narrower and more parallel form relatively narrower and more elongate elytra and
