STICTIELLA SPINIFERA (Mickel) 



IMonedula speciosa Patton, Bull. U. S. Geol. Surv., vol. 5, 1879, p. 361. 

 Monedula speciosa H. S. Smith, Univ. Neb. Studies, vol. 8, 1908, p. 383 (part). 

 Monedula spinifera Mickel, Trans. Amer. Ent. Soc, vol. 42, 1916, p. 418. 

 Stictiella melampous Parkek, Proc. U. S. Nat. Mus., vol. 52, 1917, p. 43. 



This species stands very close to speciosa, from which it differs in 

 the character of the second cubital cell and in the pattern of its 

 inaculations,

Kansas: Seward County (August, 1911, F. X. Williams). 

 Mickel reports the species from McCook and Glen, Nebr.

In a preceding paper I pointed out the possibility of Fox's scitula 

 and villosa being sexes of the same species. They are found in the 

 same locality; they have the venation of the wings the same; and 

 both have the pubescence unusually well developed. This unusual 

 development of the pubescence alone is strong evidence that they 

 are sexes of one species. So far as I am aware no one has ever taken 

 a m-ale of scitula or a female of villosa. C. L. Fox reports that E. P. 

 Van Duzee at Guaymas, Mexico, took three specimens of villosa, all 

 males, and in the same locality 13 specimens of scitula, all females. 

 I have accordingly reached the conclusion that they represent a single 

 species, and since they were both described in the same paper, I have 

 retained as the specific name the name of the species described first 

 in the preparation of that paper. The female of scitula has the 

 anterior metatarsus much flattened with the posterior border some- 

 what curved. It bears eight well-developed spines and on some speci- 

 mens one or more additional spinelike hairs. Two headless females 

 in the collection of the United States National Museum are marked 

 " type " but by whom this was done I do not know.

In his description of this species Fox associated as sexes of one 

 species males and a female that in my judgment belong to different
