38 THE CA.NADIAN ENTOMOLOGIST. 



B., on 29th June, 1901, was at once recognized as belonging to this 

 species, and it was only on transferring the specimen to another box that 

 it was seen to have simple antennie instead of those so characteristic of 

 the species to which it belongs. Examination with a lens established that 

 they are the 12-jointed simple antennae of a female. Indeed, the whole 

 head approaches more closely that of a female than of a male. On com- 

 paring the head carefully with those of three males at hand, it is found to 

 be less narrowed behind the eyes and somewhat flatter on the front. 

 Such aberrations may not be uncommon, but have not been observed 

 by me, and in a large proportion of the hymenoptera the sexes are so 

 alike in structure that similar modifications would not attract attention. 

 T. latipes has a wide distribution through Canada and the United States, 

 from the Atlantic to the Pacific, but the male only is known. In " The 

 Crabroninae of Boreal America," Trans. Am. Ent. Soc, XXII., i 29, Fox 

 says that T. (Crabro) vici?ius, Cress., will probably be placed as the 

 female of latipes eventually. I have not examples of this form, but the 

 description of it supports such a view, and it is known only in the female 

 sex. It is recorded by Fox from Colo., Nebr., Nev., Ariz., Cal., Oreg., 

 Mont, and Wash. In Mr. Leaviti's specimen the scape of the antennae 

 is yellow, with a black line above, as in other males of latipes ; in 

 vicimis the scape is described as yellow, sometimes spotted behind wiih 

 black. 



THE COCCINELLID GENUS SMILIA, WEISE. 



BY T. D. A. COCKEREI.L, E. LAS VEGAS, N. M. 



The small Coccinellid?e commonly known as Smilia are among the 

 more important natural enemies of the Coccida\ The name Smilia 

 properly belongs to a well-known genus of Homoi)tera, so in Science 

 Gossip, 1900, p. 606, I proposed to call the Coccinellid genus Epismilia. 

 I now learn from the Index Zoologictis that Epismilia was used in 1859 

 for a genus of Coelenterates. I therefore propose another name for 

 Smilia, Weise, namely, Microweisea. The North American species are 

 Microweisea misella (Lee), M. tnarginata (Lee), M. coccidivora 

 (Ashm.), M. ovalis (Lee), M. atronitcns (Casey), J/, minuta (Casey), 

 M. planiceps {CAsey), M rcversa (Fall); all standing in our lists under 

 Smilia. 



Stictomela, Weise, from E. Africa, and Platylcemus, Weise, are also 

 homonyms, and will have to be changed.
