DESCRIPTIONS OP NEW SPECIES. 191 



pallidam communem includente ; antennis corpore paulo lougioribus. 



Long. 6 mm. 



Two , Cape San Lucas, Mr. Xantus. Varies with the elytral 

 markings obsolete. Of the same form as P. pallidum (Say) 

 (Diozodes pall. Hold., P. limuin Newm.), but quite different by 

 the markings. 



II YBODER A LEG. 



Front declivous, canaliculate, divided anteriorly by a deep 

 transverse line ; eyes finely granulated, deeply emarginate ; gena? 

 short rectangular ; palpi equal, slender, last joint slightly oval. 

 Antennas slender, scape as long as 3d joint, 3-5 gradually in- 

 creasing in length. Prothorax strongly constricted in front, less 

 behind, base as wide as the apex, sides obtusely angulated, disk 

 with four tubercles arranged in a square. Elytra wider than 

 prothorax, flat parallel, rounded at tip. Front coxa? separated by 

 prosternum, widely angulated externally, inclosed behind ; middle 

 coxae widely separated by truncate mesosternum, narrowly open 

 externally; epimera of metathorax wider in front, gradually nar- 

 rowed behind. Thighs very strongly clubbed ; 1st joint of hind 

 tarsi equal to 2d and 3d united. 



In the 9 the 1st ventral segment is very long ; the 2d deeply 

 excavated, and nearly perpendicularly declivous behind, the fol- 

 lowing joints short and retracted. 



A few flying hairs are seen on the antennas and legs. 



5O7. H. tlll)ercillata Nigro-picea, pube appressa brevi cinerea 

 vestita, prothorace elytrisque fusco-variegatis. Long. 9 mm. 



Oregon and Vancouver Island. The mottlings of the elytra 

 are not very definite, but the cinereous portions are more concen- 

 trated at the base, and in a broad band behind the middle. 



PIILEMA LEC. 



This genus resembles so closely the European Cartallum, that 

 no detailed description is necessary. It agrees precisely in form, 

 appearance, and general characters, but differs by the palpi being 

 slender, with the last joint cylindrical (not triangular), and by 

 the mesosternum being wide and truncate (not narrow and sub- 

 acute behind). The hind tibia? are somewhat curved.
