300 INIr. H. W. Bates on the 
but rather more ovate and less parallel in form ; elytra 
dark brown, not concolorous with the thorax; the hind 
thoracic angles more rectangular, and the sutural stria very 
deeply impressed. The sutural stria lies in a sutural 
depression, both depression and stria beginning at some 
distance fi*om the base, and continuing to the apex. The 
recurved striolc Avhich in TacTiyta lies near the lateral 
margin is not visible in this species; but the large punc- 
ture Avhich marks its termination is plainly visible. This 
is nearly the same in T. livida, but a shallow striolc is 
perceptible behind the puncture. There are in both 
species other large punctures parallel and near to the lateral 
margin, Avhich represent the eighth stria. The antennas 
are short and submoniliform ; the anterior tibia) obliquely 
truncated externally at the apex, and broader than in 
Tachijs. 
Tachijs aiomarius (Wollast.), Cape Verde Islands, is 
also closely allied to T. livida, and has a similar inter- 
rupted or obsolete recurved striole. These three form a 
natural sub-group in the genus.

Allied to T. Jiavipes, but Avitli dark-pitchy legs, an- 
tennas and palpi, and glossy spots on the elytra. Mots- 
chulsky's description is quite recognizable, and has the 
priority over that of Morawitz.

Distinguished from the European species of the palu-

on the sides, and gradually narroAvcd from the middle 
anteriorly ; behind the middle it is not naiTOwed, although 
the margin is strongly sinuated, the hind angles being much
