108 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 5 1 



Tachina utilis, sp. nov. 



Length, 6 to 8 mm. Differs from T . larvarum in it? much smaller 

 size, vertex of male not wider than one eye, thoracic dorsum not so 

 thickly pollinose, abdomen more shining', with pollinose bands not 

 so distinct, and anal segment not thickly hairy. The male in some 

 specimens shows signs of reddish on sides of abdomen. 



The anal stigmata of puparium also show important differences, 

 the median slit being much abbreviated. 



Germany, Bavaria, and Carniola. Bred at the Gipsy Moth Para- 

 site Laboratory, North Saugus. Massachusetts, by E. S. G. Titus, in 

 1906, and W. F. Fiske, in 1907, from both Euproctis chrysorrhoea 

 and Porthetria dispar larvae received as summer importations from 

 above localities; and also bred by W. F. Fiske. in 1007, from native 

 larva? of both species collected in field colonies near Boston (Oak 

 Island and Woburn), Massachusetts, where European specimens of 

 this tachinid had been previously liberated, showing that this species 

 has gained a foothold. 



Type. — Cat. Xo. 11.804, U. S. X. M. (male, length 6 mm.; Dres- 

 den, Germany, from Euproctis larva? collected and shipped by 

 Schopfer). 



This type specimen was submitted to Dr. K. Kertesz, and by him 

 determined as Tachina gldssatorum Rondani. It can not be that 

 species, which is described by Rondani as having the second aristal 

 joint four times as long as wide, and belongs to the genus Micro- 

 tachina established on that character. Tachina, including the pres- 

 ent species utilis. has the second aristal joint no longer than wide. 



Genus Euphorocera Townsend 

 Euphorocera slossonae, sp. nov. 



One female, Franconia, X. H. (Mrs. A. T. Slosson). Syn. E. 

 cinerea Coquillett (non van der Wulp), Rev. Tach., p. 102. 



Differs from van der Wulp's description of Phoroccra cinerea 

 (Biol. C. A., Dipt., ii, pp. 81-82) as follows: Frontalia as broad or 

 broader than the parafrontals. Lowest frontal bristles not close to 

 the eyes. Face very distinctly yellowish. Second antennal joint 

 two and one-half times as long as first, the third joint a little more 

 than twice as long as second. Arista thickened on basal third only. 

 Palpi somewhat swollen, evenly clothed with black hairs. No trace 

 of dorsal stripe on second and third abdominal segments. Two 

 discal macrochaetse on second segment as well as on third. Anal 

 segment only moderately beset with bristles. Small crossvein
