the longer hairs of the el^'tra inclined but coarse and distinct. 

 Head finely but rather closel}' punctate, the eyes large and con- 

 vex, Prothorax narrower than the head, of the usual form but 

 with the base distinctl}' narrower than. the maximmn width, the 

 punctures of different sizes, rounded, dense but not polygonally 

 crowded. Elytra three-fourths longer than wide, only very 

 slightly more than twice as wide as the prothorax, parallel and 

 slightly rounded at the sides, evenh' and not very broadly- round- 

 ed at apex ; humeri not very widel}^ rounded to the prothorax ; 

 omoplates feeble ; punctures raoderatel}^ coarse and sparse. Ab- 

 domen finely and densel}^ punctate. Legs somewhat short and 

 stout. Iiength'2.2 mm.; width 0.75 mm. 



Florida and Louisiana ( New Orleans, — LaFerte). The single 

 specimen in ray cabinet seems to be a male, judging b}^ the ex- 

 posed pj-gidium ; it has the anterior coxae angulate behind and 

 the corresponding tibite not bent but densely clothed with short 

 stiff setae within toward apex, the intermediate trochanters and 

 tibiae not modified, the fifth A-entral long, evenly and almost semi- 

 circularly rounded, unmodified on the disk and about three-fourths 

 longer than the fourth. This form of the fifth segment is very 

 different from that of hispididus, and in fact throughout the 

 present genus the species, which generall}^ resemble each other 

 very strongl}^ or adhere to a common type of structure, differ 

 strikingly among themselves in the secondary sexual modifica- 

 tions of the male. 



There are several points in the original description of pusiUus, 

 which give rise to graA'e doubts concerning the identity of the 

 present species. For example, the phrase " les yeux tres-peu 

 saillants," will not accord with this form, nor with any other of 

 the genus known to me; also " corselet. .. .retreci faiblement 

 et progressivement depuis les pommettes, qui sont pen saillantes, 

 jusque'a la base, qui ne parait nullement marginee ; " finally 

 " el3'tres. . . .presque trois fois aussi larges que le corselet et 

 plus de deux fois aussi longues que larges. . . .en oval tres-allonge 

 posterieurement." The length and width are given as 2.0 and 0.6 

 mm., respectivel}' ; that is, if these measures are correct, the in- 

 sect is proportionally much more slender than any other of this 

 part of the genus, and yet the elytra are nearly three times as 

 wide as the prothorax. Either the description is grossly- inexact, 

 or the insect of LaFerte is a very remarkable species, quite dif-
