This insect must be placed among the large vermiculate-rugu- 

 lose species of Stigmodera, but I do not know any species to 

 which I can say that it is nearly allied ; perhaps it suggests the 

 idea of Reichei, L. tfe G., as much as anything. 



In order to compare it with a well-known and common species 

 I place it beside an example of S. MitclLeUi, Hope, and tind that 

 (disregarding colour and markings) — the head differs chiefly in 

 being pilose and very much more closely and finely punctured — 

 the prothorax chiefly in being vermiculately rugulose with the 

 intervals of the rugae very closely punctulate, and also in having 

 its sides very much less strongly rounded and its front margin 

 more strongly bisinuate— the elytral sculpture is not very 

 difierent — and the sculpture of the underside differs chiefly in the 

 ventral segments being more closely punctured and a little more 

 disposed to rugulosity. The general form is much more elongate 

 and less robust than that of S. MitclteUi. The extremely crowded 

 sculpture of the prothorax seems to be a very distinctive charac- 

 ter ; it is very much more crowded than in S. grandis, Don. — 

 more so also than in *S'. Stevensi, Gehin.

 The markings on the prothorax and elytra scarcely difl'er from 

 those of /S. Mitchelli, Hope, and probably are equally variable. 

 In the two examples before me those on the elytra difl'er so much 

 (the front fascia in one being much broader than in the other, 

 and the hindmost fascia in one being reduced to two spots) that 

 it would be waste of space to describe them. The species is very 

 near to S. Mitchelli, but very distinct, diflering from the corres-
