PODISUS. 39 
The specimen figured is from Mexico, and differs from the type in having the pro- 
notal angles more acute. This, however, seems a very variable character, judging from 
an examination of North-American specimens in the British Museum. Some have the 
angles subacute, as described by Mr. Dallas; one has them as acutely produced as in the 
above Mexican form, whilst another, from Lake Huron, partakes of both characters, 
having the right spine prominently acute and the left subacute. Prof. Uhler records 
having swept this species from bushes in Colorado during the early part of August; 
and, according to Mr. Fitch, in New-York State “this is one of our common tree-bugs, 
and will be met with in autumn upon a number of different trees and shrubs.” Mr. 
Townend Glover quotes Prof. Riley for the fact that it destroys the caterpillars of 
Hemileuca mata.

10. Podisus insignis, n. sp. (Tab. IV. fig. 15.) 
Above luteous, shining, punctured with rosy brown. Head impunctate, anterior and lateral margins and 
margins of central lobe beyond eyes shining fuscous; base with some obscure rosy markings; eyes black. 
Pronotum with the lateral angles produced into prominent acute spines, with the tips black; lateral 
borders with a submarginal row of brown punctures, a central cluster of brown punctures near base, on 
each side of which is a smaller and less dense aggregation of punctures of the same colour, a few punc- 
tures scattered across anterior portion of disk; remainder of pronotum impunctate, glabrate. Scutellum 
glabrate, a few punctures at centre of base and each basal angle, and two longitudinal bands of punctures 
at apex. Corium thickly punctured with rosy brown, and with a transverse, impunctate, opaque silky 
fascia extending half across from inner side of apical margin. Membrane pale hyaline. Abdomen above 
pale reddish; connexivum alternately luteous and rosy brown. Body beneath luteous, abdomen some- 
what punctured and mottled with brown. Legs luteous, femora spotted with brown; rostrum luteous, 
apical joint rosy brown. Antenne luteous, with the second joint much longer than the third, which is
