with distinct serrations at or near the base of the dorsal edge. The individual 

 glands forming the compound marginal groups, circular ; central orifice escutcheon- 

 like ; periphery with from 2-4 clear, bead-like processes ; when two of the latter

 a triangle, and when four in number they are equilaterally placed. Length 

 (average), 4 mm.

The tests of this species bear a very strong resemblance to those of T. decorella. 

 Mask., but they are generally larger and less regular in form. The female differs 

 from the latter in the great length of the hairs of the anal ring ; and from 

 T. actinella, Cockerel!, in the absence of antennas. 



A large percentage of the insects are infested with Chalcidids.
