On Trifolium pratense, on which the larva produees a gall; introduced as 
British by Mr. Crotch on the authority of a single specimen taken by him about 1863 
at Cambridge and named by M. Brisout; the species is so closely allied to the pre- 
ceding that it certainly appears to require further confirmation before being finally 
regarded as indigenous.)

brown or greyish brown scales, underside lighter ; rostrum subulate and 
bright red in front of the insertion of the antennw, base pubescent ;

broader than thorax, with the strie either distinct or more or less 
covered by the scales, unicolorous or with suture lighter ; femora dark, 
tibie and tarsi rufo-testaceous. L. 2-25 mm. 
Male with the anterior tibize furnished with a smali tooth on their
