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

 retains it as distinct on dittorcMices in the comparative position 

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

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

 There is, however, another character quite sufficient to 

 separate Rhophitulus from Macrotera, viz., the large stigma ; 

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

 and M. secunda, Ckll. (lOO-i) — the stigma is small and 

 linear. 



CaLLIOPSIS, Smith.

 Culliupsis Jlavipes, Smith, /. c. p. 129. S ■ 



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 C. Jlavipes, 

 Smith. I am unahle to trace C. flavifrons, Smith, referred 

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

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

 British Mu>eum.

In the Edward Saunders Collection are 2 ^ (S and 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 nie in this synonymy, and says that 

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

 find a record of it.
