linear depressed form. It is allied to Cardiola, but differs in its 

 parallel form, in the more elongate second antennal joint, more 

 prolonged mesosternal process, shorter basal joint of the hind tarsi, 

 and in having a fine distinct basal margin of the pronotum with 

 well-defined basal angles. It resembles Cardiola in the absence of 

 a dividing line between the pronotum and its inflexed flanks. 



A. SUlcifrons n. sp. — Polislied, piceous-black, the antennae concolorous 

 tlirougliout ; elytra and legs dark piceous-brown ; punctures very minute 

 sparse and subgranuliform, except on the abdomen, where they are a little 

 larger, more distinct and nearly simple or slightly asperate ; pubescence fine 

 and sparse but rather long and distinct. Head slightly longer and much 

 wider than the prothorax, the eyes at one-half more than their own length 

 from the base ; antennae about as long as the head and prothorax ; surface 

 with a coarse deeply excavated groove extending from the apical margin 

 behind the middle, there becoming finer to the base. Prothorax fully as long 

 as wide, widest at apical fourth where the sides are very strongly rounded, 

 thence extremely oblique to the neck and distinctly convergent and nearly 

 straight to the base, the latter truncate ; disk transversely convex, with a 

 deep median sulcus extending from base to apex. Elytra about as large as the 

 head, distinctly wider and longer than the prothorax, subquadrate, parallel 

 and straight at the sides ; humeri broadly exposed at base ; disk flat, narrowly 

 impressed along the suture. Abdomen at base distinctly narrower than the 

 elytra, but, at apex, subequal in width ; border thin, nearly vertical. Length 

 1.4 mm. ; width 0.3 mm. 



Florida. 



The deep sulcus of the front may be a sexual peculiarity, in part 

 at least. 



BOLITOCHARIDES. 

 Antennae 11 -jointed ; tarsi 4-4-5-jointed. 



APHELOOLOSSA n. gen. 



Body elongate, subparallel and subdepressed. Head rather large, 

 transverse, narrowed toward base but scarcely constricted, the eyes 

 rather large, convex, setose and prominent, at less than their own 

 length from the base ; infralateral carina feebly traceable, inter- 

 rupted and nearly obsolete, antennae rather long, thick, feebly incras- 

 sate, finely pubescent, bristling w^ith long sparse setae, the basal 

 joint thicker and much longer than the second or third, the latter 

 equal, elongate ; fourth subquadrate ; tenth one-third wider than 

 long ; eleventh ogival, as long as the two preceding. Mentum
