may be synonymous with Macrotera^ Smith (1853), but 

 retains it as distinct on differences in the comparative position 

 of tlie ocelli. I have examined types in both genera con- 

 cerned, and find no difference in the position of the ocelli. 

 Tliere is, however, another character quite sufficient to 

 sei)arat.e RhopJiitulus from Macrotera, viz., the large stigma ; 

 in both known species oi Macrotera — M. bicolor, Smith (1853), 

 and M. secu?ida, Ckll. (1904) — the stigma is small and 

 linear.

These two insects were both described from specimens 

 taken by Edward Doubleday in East Florida, and are 

 certainly only the sexes of one species. In the British 

 Museum is a pair from N. Dakota (G. A. Stevens) presented 

 by Prof. Cockerell ; the male agrees perfectly with G.Jlavipes, 

 Smith. I am unable to trace C. fiavifrons^ Smith, referred 

 to by Cockeivll (Trans. Amer. Ent. Soc. xxxi. p. 321, 

 1905), the type of which is recorded as being in the 

 British Museum.

In the Edward Saunders Collection are 2, S S ^»d 2 ? ? 

 identified as Erichson'sspecies,no doubt correctly. Mr. Morice 

 lias presented a pair of co-types of P. moricei, Fr. ; this 

 species is described from the same series as those labelled 

 P. venustus by Saunders ; all were captured by Mr. Morice 

 in the same locality on the same day, namely, Jimena, Anda- 

 lusia, i. v. 1905. Friese places P. venustus in Gamptopceum. 

 Mr. Morice agrees with me in this synonymy, and says that 

 he thinks Friese has noticed it himself; but I am unable to 

 find a record of it.
