Nine niales (including three of the variety with a red prothorax) 

 and live females. A form of the equally variahle D. aj)j}eudiculafa Pie, 

 with more shining elytra, the interstices of which are less densely rugose ; 

 the (S with undilated, simply sinuate intermediate tibiae, a shorter tooth 

 on the posterior femora, and the opaque patch on the elytra wanting.* 

 The females vary infer se, the two from Santa Catharina being larger 

 and broader than the others, and they may not really belong here. 

 Maklin's description of Statira obscura applies fairly well to specimens 

 of this sex. D. dentatipes (1911) and D. tijucana Pic (1912), types, 

 6 6 , have somewhat similarly toothed or lobed intermediate femora 

 in male.

(S . Moderately elongate, narrow, shining; head, antennae, and opaque 

 Literal depression of elytra black, the prothorax aud basal halves of femora 

 testaceous, the rest of the insect piceous, the elytra brownish at the base; 

 somewhat thickly clothed, the legs included, with long-, tine, bristly hairs. 

 Head small, the eyes moderately large, narrowly separated, not reaching the 

 base; antennae long, stout, strongly serrate from joint 3, 11 curved, nearly 

 equalling 8-10 united, flattened aud asperate on its inner face. Prothorax 

 convex, longer than broad, moderately rounded at the sides, constricted before 

 tlie prominent basal margin ; closely impressed with intermixed coarse and fine 

 punctures, triangularly depressed at the base, and canaliculate anteriorly. 

 I'^lytra moderately long, widening to the middle, and there twice the width of 

 the prothorax ; finely, deeply crenato-striate, the interstices convex, each with 

 a row of somewhat closely placed, small, setigerous impressions ; the depressed 

 opaque lateral patch long, oblique, extending between the striae 4 aud 8. 

 Ventral segment 5 excavate in the centi'e aud emarginate at the apex. 

 Anterior tibiae abruptly bowed iuwards at about the middle, deeply bisinuate 

 within ; intermediate tibiae dilated and compressed, twisted towards apex ; 

 [posterior legs wanting].

One male. Narrower than D. appendiculata Pic, the eyes larger 

 and more approximate, the antennae shorter, the prothorax oblongo- 

 cordate, the elytral interstices uniseriate-punctate, etc. The much
