I am not at all sure of the position of this genus, the dilatation 

 of the tibiae in the male is so slight as to be in most instances 

 unnoticeable. 



103. — Ctclothorax punctipennis. n. sp. 



Length 2| lines. 

 Black, nitid. Head smooth with a deep line on each side near 

 the eyes. Thorax emarginate in front, much rounded at the 

 sides and base, with a narrow red reflexed margin ; the basal 

 portion depressed and punctured, and the remainder smooth and 

 without median line. Elytra each with six light striae marked 

 with well defined punctures, which become less distinct towards 

 the apex, and in the sixth striae do not extend beyond the middle ; 

 there is also a punctured sublateral stria. A very narrow reddish 

 border is traceable along the sides and hinder portion of the 

 suture. The legs, antenna, and palpi, are of a pale red. 



104. — Abacetus ater. n. sp. 

 Length 2| lines. 

 Black, nitid. Head small with a short deep curved impression 

 on each side in front. Thorax much broader than the head, and 

 a little broader than the length, emarginate anteriorly, much 

 rounded on the sides, and truncate at the base. The median line 

 is distinct, and takes its rise at some distance from the apex, and 

 the two basal impressions are deep, long, and linear. The lateral 

 margin is small, reflexed, and of a reddish hue. Elytra scarcely 

 broader than the thorax at its broadest part, and deeply striated, 

 with small punctures visible in the striae, and with the interstices 

 broad and convex. Legs, antennae, and palpi pitchy red. 



105. — Abacetus angdstior. n. sp. 

 Length 2 1 lines. 

 This species nearly resembles the last ; it differs in the thorax, 

 which is less emarginate in front, less bulged out and rounded on 

 the sides, and which is rather longer than the width. The elytra 

 differ in having the striae smaller, and the interstices much more 

 flat. The legs and palpi also are of a lighter colour.
