84. Ati'opIiopo<la singularis Towns. 



On pp. 378-375 of Trans. Am. Ent. Soc, vol. xviii, I gave a de- 

 sci-iptioii of the new genus AtropJwpoda, from two specimens from 

 Illinois. Although both sexes are indicated in the description, I 

 believe that I had females only under inspection. In a collection 

 of Tachinidse sent me by Prof. Forbes, from Illinois, I find 27 speci- 

 mens wdiich seem to be this species. Of these, 12 are the typical form 

 of my descriptions, and are apparently the female sex, while 15 are 

 apparently the same species, and if so, must be considered the males. 

 They differ by having the eyes pronouncedly hairy, the antennse 

 greatly enlarged and bypertrophied, and the claws and pulvilli of 

 all the feet elongate — the same form described by me as Laclntonuna 

 in Trans. Am. Ent. Soc, xix, pp. 103-105. I desire to point out 

 the possibility of these two forms being male and female, since the 

 suspicion has come to me. If it is so shown, the name AtropJwpoda 

 has priority over the other. Some of the Lachnomma form are much 

 smaller than the typical. However, the typical specimens of Lach- 

 nomma do not possess the vittate thorax characteristic of the above 

 specimens. 



85. Epigriiiiyia polita Towns., Trans. Am. Ent. Soc, xviii, 375-376. 



One specimen from southern Illinois (Robertson) does not differ 

 from the type described from D. C. It was taken by Mr. Robertson 

 on flowers of Blephilia sp. 



86. PseiKloniyothyria n. sp. 



Length 4.5 mm. ; of wing, 3.5 mm. — Eyes brown, frontal vitta brown ; sides of 

 front, face and cheeks silvery ; two orbital bristles, directed strongly forward ai d 

 a little outward ; antennfe and arista black, third antennal .joint four times as 

 long as second, rather stout ; proboscis brown, palpi pale rufous ; occiput cinereous, 

 spar.sely hairy. Thorax silvery, with four narrow blackish vitta? anteriorly ; 

 scutellum blackish, silvery pollinose. Abdomen shining black, bases of second 

 to fourth segments broadly silvery pollinose, the third segment faintly and the 

 fourth markedly with a golden shade ; second and third segments have the ]iollen 

 divided by a non-pollinose black median band : first and second segments with a 

 median marginal and a lateral marginal pair of macrochsetse, third with eight 

 marginal, anal armed with marginal and submarginal macrochsetse. Legs black- 

 pulvilli and claws small. Wings grayish hyaline, tegulse white ; halteres brownish 

 testaceous. 



Southern Illinois (Robertson). This species differs somewhat from 

 the tyjje of the genus in not having the facial ridges ciliate more 

 than half way up the face. 



87. Vanderwulpia atropliopodoicles Towns. 

 Socorro, N. Mex., August 8 ; one specimen. 



88. Scopolia n. sp. 



Southern Illinois ( Robertson ) ; one specimen. Differs from Schiner's 

 description of Scopolki by having a more nearly ovate, instead of a
