closer. Scutellum extremely short and broad, with a notch 
in the middle of the apex, so that it seems to consist of two 
parts. ytra parallel-sided, apices strongly rounded indi- 
vidually, with an elongate sutural gap, the shoulders slightly 
raised and a little wider than the thorax in line with and 
including the lateral tubercles; on each elytron there are 
three ivory-like streaks—one is close to the suture, none 
attain the apex, the central one is the shortest; the punc- 
tures are reddish, rather fine, regular, and not at all close as 
far as the middle, behind this they become large but shallow 
and more distant, and they lose the red colour, 
Antenne pubescent, the hairs neither very long nor coarse ; 
first joint closely punctured, the third joint reaches the base 
of the thorax, it is slightly longer than the fourth, but shorter 
‘than the fifth; the eighth attains the extremity of the body. 
Underside yallid, the head punctate, transversely grooved 
behind; prosternum punctate, with some ruge across the 
middle; metasternum with a median groove, it is finely 
punctured and transversely wrinkled; terminal segment of 
abdomen transversely quadrate, truncate behind, with long 
pubescence. 
D. egrota, Bates, is the only similar form ; in it the thorax 
is more narrowed anteriorly, the hinder tubercles are placed 
behind the middle, the insect is darker and more closely and 
coarsely sculptured, the antenne are thicker, and the head is 
narrower.

Hybolasius optatus, sp. n. 
Oblong, robust, rufo-piceous ; legs and antenne pale infus- 
cate red, the two basal joints of the tarsi darker than the 
others ; rather closely covered with greyish-yellow decumbent 
hairs, on the elytra they are thinner or absent on some parts 
so as to cause a spotted appearance. 
Head finely sculptured, slightly impressed near the hind 
margin of the eyes. Thorax broader than long but not short, 
with very fine indistinct granular sculpture, which, however, 
is better defined and closer on the basal depression; lateral 
tubercles large but not acute, placed behind the middle; on 
the disk before the middle there is a pair of very slight 
elevations ; there is no frontal constriction, there being only 
a superficial transverse depression. Scutel/um densely pilose.
