Del Guercio found it in numbers on one to two-year-old 
shoots of Larix in the Park at Pratolino in the spring of 1907. 
It is quite distinct from any others seen by this Italian Aphi- 
dologist and is certainly not Walker’s Larix species. I record 
it under Del Guercio’s generic name.

Black ; re pale, belly at base, all the tibize and fore and middle 
femora testaceous; hind femora testaceous with apices above dark ; 
tarsi pale fuscous ; all the cox black or blackish, the hind pair sub- 
rugulose above. Antenne of the female as long as the body. 
Mesothorax subrugulose, almost as deeply marked as the first and 
second abdominal segments; scutellum smoother ; metathorax rather 
coarsely rugulose; wings somewhat clouded; stigma and nervures 
pale fuscous; first segment of the abdomen truncate, at the apex 
almost as broad as 2, narrowed towards base, 2 slightly shorter 
than 3, first and second rugulose, the remainder smooth and 
shining; spurs of the hind tibiz shorter than half the metatarsus ; 
terebra shortly exserted. Length 2? mm., expands 6 mm. 
Described from two males and twelve females. 
Cocoous white, woolly, affixed to a stem of grass in a rather 
compact, irregular bunch without external covering (fig. 4). 
Differs from congestus in that the terebra is twice as long and the 
cocoons totally different; from vestalis in that the scutellum is 
smoother, terebra longer, and ventral valve smaller ; from ruficrus 
in having the fore coxe dark and not testaceous, etc. ; and from 
tetricus in that the terebra is longer, third abdominal segment 
not rugulose, and legs much lighter. 
During the first week in July, 1908, I found a bunch of some 
twenty cocoons firmly attached to a stout stem of grass some 
six inches above the ground; from these, on the 11th of the 
month, I obtained imagines of a species which I at first took to 
be congestus, though I could not account for the difference in the 
cocoons ; careful examination, however, revealed several differ- 
ences in structure, etc. 1 have never met with the species 
since.
