Sima rufo-niger, Roger, Berl. Ent. Zeitschr. vii. 1864. 
Female.—Length 5 lines. The head, femora, inter- 
mediate and posterior tibize and the abdomen black ; the 
antennee, mandibles, tarsi, anterior tibize: and base of the 
two following pairs pale ferruginous; the thorax and two 
nodes of the abdomen ferruginous; the anterior wings 
fusco-hyaline ; the posterior pair clear hyaline; the ner- 
vures of the anterior pair fuscous, palest at the base of the 
wings; the stigma dark fuscous. For the neuration, see 
the figure in plate. 
Roger separated this insect from the genus Pseudo- 
myrma, creating the genus Sima for its reception ; but, in 
my opinion, on insufficient generic characters. Finding 
on comparison with six species of Pseudomyrma, some of 
which are retained in that genus by Roger, that the neura- 
tion of the wings in P. bicolor is identical with the others, 
I do not. adopt the proposed generic name. The male of 
this species is unknown to me. 
MUTILLIDA. 
Methoca orientalis. 
Male.—Length 31 lines. Black and shining; wings 
hyaline; the nervures and stigma black. Antenne as 
long as the head and thorax, thickened in the middle ; the 
face closely punctured, the vertex more sparingly so ; 
the mandibles rufo-piceous; the palpi pale testaceous; the 
entire insect with a thin, scattered, griseous pubescence, 
particularly:the head and thorax. Thorax: the pro- and 
meso-thorax anteriorly with fine, rather distant punctures; 
the posterior portion of the mesothorax with transverse, 
somewhat coarse striz ; the metathorax rugose; the tarsi 
obscurely testaceous. Abdomen very smooth and shining; 
the margins of the seements constricted. 
This insect closely resembles the Methoca ichneu- 
monoides of Kurope; but its antenne are thicker, and the 
transverse striation of the mesothorax distinguishes it. It 
is the first species of the genus I have any knowledge of 
from India.
