234 DESCRIPTIONS OF NEW SPECIES. 



tincta, alteraque obliqua usque ad medium extensa, fasciculis solitis 

 parvis nigris, plaga magna laterali ante medium, fasciaque obliqua pone 

 medium nigricantibus ; fascia pallide pubescente paulo pone medium 

 ornatis ; anteunis cinereis, fusco punctatis et annulatis. Long. 9 mm. 



Louisiana ; this species is sufficiently distinct by the disk of 

 the elytra being flattened in front, limited each side by an oblique 

 well-defined line, exterior to which is the line defining the abrupt 

 declivity of the sides ; towards the tip they are regularly rounded, 

 scarcely prolonged, and obliquely truncate at the extreme tip. 

 The small tufts of black hair are well developed ; there is a large 

 lateral dark blotch extending from the side to the oblique ridge, 

 behind which is a broad band of paler cinereous, somewhat as in 

 well marked specimens of L. macula ; behind this pale fascia the 

 pubescence is dark, with an oblique band composed of two blackish 

 spots, and then a subapical dark cloud. Beneath covered with 

 cinereous pubescence, medial band and apex of tibia, and tarsi 

 blackish. 



562. L. parvus. Testaceus, pube subtili dense vestitus, prothorace 

 dorso obsolete tuberculato, lateribus obtuse angulatis ; elytris apice sin- 

 gulatim rotundatis, parce fortiter punctatis, tuberculis parvis penicella- 

 tis parcis ornatis ; capite thoraceque obscnrioribus, anteunis tibiisque 

 piceo-annulatis. Long. 4 mm. 



Two specimens ; Western States. A robust little species, very 

 easily recognized ; the disk of the elytra is obliquely impressed in 

 front of the middle, and the post-humeral compression is quite 

 distinct. 



STFR \inil S Lec. 



This new genus is founded upon the species of Div. C of my 

 arrangement of Liopus, (Journ. Acad. Nat. Sci. Phila., 2d ser. 

 ii, 112). They differ from Leptostylus by the 1st joint of the 

 hind tarsi as long as the two following, and from Liopus by the 

 mesosternum being broad and truncate between the coxae. The 

 thoracic tubercle varies in position but little, and is about one- 

 fourth to one-third from the base, obtuse, but not rounded ; the 

 sides are emarginate behind the tubercle, but straight and ob- 

 lique in front of it ; there are no dorsal tubercles.
