ciding to which of the two it should be applied, I am obliged to 
pass it over without further notice. 
17. Nyssodrys propinqua, n. sp. 
N. oblonga, subdepressa, bmnnea: elytris fasciis duabus obscurioribus 
plagammagnamcineream includentibus maculaque parvasubapicali, 
apice oblique sinuato-truncatis, angulis prominentibus : $ seg- 
mento ventrali ultimo integro, truncato. Long. 3-4 lin. S 2 • 
(7 exempl.) 
Head ashy brown. Antennae rusty red, tips of joints dusky. 
Thorax widened from the front to the tips of the spines, which 
are short and conical, and placed nearer the middle than the hind 
angles of the thorax, the space between them and the base being 
moderately narrowed ; surface silky brown. Elytra oblong, apex 
obliquely and rather strongly sinuate-truncate in both sexes, 
angles prominent ; surface thickly punctured over the basal half, 
dingy brown, with two dentated fascise of a darker shade on each 
elytron, — the basal one anteriorly blending with the ground- 
colour of the wing-case, the second more distinct and very broad 
on the lateral margin, neither touching the suture, the space 
between them being of a light ashy colour ; near the apex is a 
small rounded dark-brown spot, encircled with ashy, which in 
many examples extends laterally towards the margin. Body 
beneath and legs clothed with tawny-ashy pile. 
S Apical ventral segment broadly emarginated. 
2 Ovipositor rather short, extending only | of a line beyond 
the tips of the elytra ; dorsal plate acute, ventral truncated and 
entire at the tip. 
The present species is almost identical in markings with the 
preceding, but it differs by its much smaller size, dingier colours, 
more sinuated truncature of the elytra, and by the apical ventral 
segment of the female being entire instead of notched at the 
apex. It is a generally distributed species in the Amazons re- 
gion, but occurs much more commonly than N. signifera. Spe- 
cimens from Cayenne, under the name of Leiopus hieroglyphicuSj 
have been sent to me from Paris. 
18. Nyssodrys simulata^ n. sp. 
N. oblonga, subdepressa, brunnea ; elytris utrinque plaga canescente 
fusco maeulata ante medium, macula dentata lateral! alteraque 
parva subapicali fuscis, apice sub transverse sinuato-truncatis.
