AMERICAN COMPONENTS OF THE TENTYRIIN^ 497 



for example the posteriorly flexed basal margins of the elytra, 

 becomincT the innermost of the fine discal threads of the dorsal 

 surface, and the fact that the abdomen becomes more minutely 

 and sparsely punctate posteriorly, instead of more densely as is 

 the general rule. No sexual marks can be perceived in the 

 specimen before me. 



Tribe Batuliini 

 In Batuliodes, provisionally assigned to this tribe, the antennae 

 are as in Typhlusechtis, only much more elongate and are per- 

 fectly free, not being received in grooves, and there seems to 

 be a premonition of the trochantin becoming so distinct in An- 

 e^shis, the sterna coming together at a very large deep suture, 

 which is much more open near the coxae than in any of the 

 preceding tribes. The body is very small in size, oblong-oval 

 and not linear or with the hind body dilated as in the Daco- 

 derini or Araaoschizini, but resembling Anepsius completely. 

 The two genera may be described as follows^ : — 



Body larger, sparsely pubescent ; prothorax not so basally narrowed ; 

 eyes not at all divided ; clypeus not emarginate anteriorly ; 

 antennae short, apically incrassate ; mentum and palpi nearly as in 

 the preceding ; anterior tibitE strongly dilated, subdentate ex- 

 ternally. [Type B.setostis Lee] Batulius 



Body oblong-oval, evenly and moderately convex, glabrous ; head 

 trapezoidal, transverse, scarcely constricted at base, the clypeus 

 large, transverse, virtually concealing all the mouth-parts from 

 above, the apex broadly emarginate, the bottom of the emargi- 

 nation broadly arcuate, the lateral lobes somewhat advanced, 

 prominent and narrowly rounded, the lateral sutures short and 

 feeble, the supra-antennal prominences very feeble ; mandibles 

 small, slender, bifid at tip ; mentum moderate, subquadrate, 

 obliquely narrowed toward base, exposing the entire maxilla; but 

 covering the short broad ligula, the palpi small, moderately 

 slender, the last joint of the maxillary narrowly oval, obtusely 

 pointed, longer than the preceding; eyes basal, moderately large, 

 on the sloping sides and giving no vision directly beneath, coarsely 

 faceted, completely divided by the anterior canthus, which extends 

 to their transverse hind margin, both segments narrow, elongate 

 and deeply sunken, the inner segment bounded internally by a very 

 short and feeble ridge, the outer externally by the slightly extended 

 under surface ; antennae moderately long, slender, subglabrous 



'The characters of the tribe Batuliini, given on page 2S2 of this paper, are 

 taken from Batuliodes roiundicollt's, and may not therefore be truly those of the 

 tribe as represented by its proper type, which is Batulius setosus Lee.
