INSECT A. 
179 
*1. latipes, Walk. — A still smaller species, having a shiny black 
body, measuring only two and three-quarter lines in length. 
Cryptus, Fabr. 
* 0 . triangulifer, Walk. — An insect very similar to the last, and 
about the same size, with a black body. The specimens were taken 
with the Ichneumon hies. 
Pimpla, Fabr. 
*P. sanctse helense, Walk. — A large black-bodied Ichneumon 
Fly, perhaps more abundant than any of those before mentioned. 
Frequently it is seen in houses at night, and generally about gar- 
dens on the high land as evening approaches. The length of the 
body is from five and a half to seven and a half lines, and it is easily 
recognised by its being the largest of those flies which have a black 
body. It selects the large green caterpillars of Plusia aurifera in 
which to deposit its eggs ; and many chrysalides which I watched 
with much care, hoping to see the rightful occupant emerge, yielded 
only one of these troublesome creatures. 
Paniscus, Grav. 
*P. pieeus, Walk. — A large red-bodied Ichneumon Fly, more 
abundant still than any of the aforementioned. The length of the 
body is from seven to nine lines. On the high land, at night, these 
flies come into the houses in considerable numbers and behave in a 
very disagreeable manner ; they dash into your face with unpleasant 
force, and I have often seen them extinguish the flame of a candle 
by tumbling into it one on the top of another, until they literally 
choke it out. 
Fam. Braconidts. 
Alysia, Latr. 
A. eephalotes, Hal. — An extremely minute Ichneumon Fly, 
taken at The Hermitage on the high land, and not abundant. It 
also inhabits Madeira. 
Fam. Chalcidias. 
Pteromalus, Swederus. 
*P. ipsea, Walk. — A small green Fly, taken by Mr. Darwin 
from the high central land, and, with the following species, described, 
by Mr. Walker in his “ Monographia Chaleiditum,” vol. ii. p. 97,
