1933 ] A Second Parasitic Crematog aster 85 
Creighton comprise three workers, three females and a 
male. 
The worker closely resembles the typical lineolata in form 
and sculpture, but the head is smoother and more shining 
posteriorly and the epinotal spines, though fully as long as 
in lineolata, are distinctly more slender and tapering and 
even more acute at their tips. The pilosity is conspicuously 
longer and more abundant on all parts of the body, and, 
on the antennal scapes and legs, long and suberect, whereas 
in lineolata and its varieties these parts have only a dilute 
and appressed pubescence, though of somewhat variable 
length in specimens from different localities. Color brown 
or brownish red, with the head somewhat darker and the 
gaster piceous or blackish; mandibles sometimes yellowish 
and paler than the head ; funiculi, except their tips, usually 
paler than the scapes. 
The female (undescribed) measures 8.5 - 9 mm. and is of 
the same size and deep piceous or blackish coloration as the 
typical lineolata, but the wings have their basal two-thirds 
distinctly tinged with brown and the veins and pterostigma 
are dark brown, instead of white as in lineolata. Pilosity 
like that of the worker, much more abundant and conspicu- 
ous on all parts of the body, long and suberect on the an- 
tennal scapes and tibiae. Even the wing-membranes are 
distinctly more pubescent than in the female lineolata. An- 
terior two-thirds of head more shining, more sharply and 
more coarsely rugulose, with less distinct punctulation or 
reticulation between the rugae. 
In the absence of authentic males of pilosa I am unable to 
decide whether the single male sent me by Dr. Creighton 
belongs to the host or to the parasitic species. Its very 
small size (only 3 mm.) might indicate that it belongs to 
the latter. Though the head and thorax are almost hair- 
less, the pilosity of the legs is like that of the pilosa worker. 
The mandibles are narrower than in the male of the typi- 
cal lineolata and have only 2 instead of 3 or 4 teeth. The 
color of the body is deep black, with brown legs and an- 
tennal funiculi and more reddish scapes and mandibles. 
The wings are distinctly yellowish at the base, with brown 
veins and pterostigma, and therefore resemble the wings 
of the female pilosa.
