“Very large, long oval, abdomen pointed. Dull sooty- 
black or greyish black, with a faint greyish medial stripe. 
Prothorax with a blunt tooth-like process on each side. Two 
broad pale grey patches on each side of the first abdominal 
ring—smaller patches on each side of the succeeding rings, 
those at and below the insertions of the cornicles being the 
largest. Antenne orange red. The seventh joint small, hardly 
equal to the sixth. The cornicles bright orange, skittle-shaped, 
with dilated mouths; very short. Legs orange, with dark 
tibial joints and tarsi. The whole insect pilose. The under- 
side is of obscure greyish-green. Rostrum long, reaching to 
the third coxe. The young insects are black and prettily

‘Very large, ee black, ee Antenne short, having 
all joints black except the third and fourth, which are orange. 
Abdomen with two or more grey dorsal patches. Cornicles 
bright orange. Legs as in the larve. Eyes dark brown. 
Wings ample.’’ ‘‘All veins are black and strongly marked.”’ 
The writer finds that the antenne reach to the middle of 
the abdomen and that the third segment is the longest. From 
14 to 20 round sensoria, irregularly placed on the inner side, 
occur on the third segment. The wings have dark veins as 
indicated, but hardly appear different from those of other 
species. The nectaries are the distinguishing characteristic 
as they are quite distinct in shape. See drawings.

Melanoxantherium flocculosus (Weed) 8a, #4. 
Melanoxantherium flocculosum (Weed) Schouteden. 
Melanoxantherium flocculosum (Weed) Gillette. 
That this species commonly occurs in Europe is shown by 
the fact that the writer has received specimens both from 
Russia and France, and Schouteden has recorded it from Belgium.
