CEROPALES. 75 



black, slightly shining ; the first segment narrowed into a long 

 petiole ; the seventh with a white spot at the base ; the sixth 

 ventral segment emarginate. 



In 1 853, 1 bred both sexes of this species from cells constructed 

 of mud, very similar to those formed by the different species of 

 Pelopceus. The male is undoubtedly the P. punctum, and the 

 female the P. petiolatus. Shuckard says, under P. punctum, 

 " With the female, which Van d. Linden considered to be P. 

 petiolatus, I am unacquainted ; " whereas the male which he 

 described as belonging to P. petiolatus was only a variety of the 

 true one, which is described above. The white markings on the 

 face are frequently more or less obsolete, and the metathorax is 

 as distinctly transversely striated in the male as in the female. 

 I have, through the kindness of M. Desvignes, who possesses 

 the Shuckardian Collection, compared the specimens of P.punc- 

 tum, and find them undoubtedly the same species as the one 

 described. 



This species is very local ; but it occurs about London, and 

 has been taken at Canterbury, Bexley, and Birch Wood, Kent. 

 Mr. Westwood has repeatedly taken it in his garden at Ham- 

 mersmith.
