Setina. Guen^e (Ann. Soc. Ent. Fr. 4® s^r. tome iv. pp. 399-401) states 
that the tympaniform vesicles observed by Jiim on the pectoral region of the 
males of Sdina are, as he supposed, organs of sound. The sound emitted is a 
sort of crepitation, but its object and the means by which it is produced are 
alike unexplained. Guen^e likewise discusses (/. c. pp. 401-404) the question 
of the specific distinctness of the forms described under the names of S. ra- 
mosa, huMtceini, and aiirita^ Avhich have been regarded as belonging to the 
same species. His opinion is that the three are distinct.

Giienee describes and figures the female and larva of Lithosia vitellina 
(Boisd.), Ann. Soc. Ent. Fr. 4® ser. tome v. p. 306, pi. 8. fig. 4. The male of 
this species is the L. pallifrons (Zell.) He also remarks upon the distinctive

of riffellensis. Ann. Soc. Ent. Fr. 4* s^r. tome v. pp. 97-100, pi. 2. fig. 2. 
The habits of Setina huhlweinii are described by Zeller, who also refers to 
the variations of the species observed by him in abundance at Meseritz. He 
likewise indicates the diflerences between this and allied species, regarding 
it as identical with Freyer’s S. complecta^ but distinct from S. roscida. Stett, 
ent. Zeit. 1865, pp. 30-37.
