lection of the Boston Society of Natural History. There is no 
evidence of the palpi being present in the specimen, and as these 
do not appear to be hidden in the oral cavity, nor the specimen to 
have been injured at this point, it is not improbable that more 
material will prove this species generically distinct. 
Pelatachina pellucida Coq.! 
During May, 1912, the writer reared specimens of this species at 
the Gypsy Moth Parasite Laboratory. The tachinid maggots had 
emerged from the larve of Euvanessa antiopa Linn., during the 
month of August, 1911, hibernating in the puparia through the 
winter of 1911-12. From 344 of the lepidopterous larve taken in 
the Lynn Woods, Mass., 214 puparia of this tachinid were obtained. 
Superparasitism existed to a great extent in the host larvee, thus, 
the figures do not indicate the exact percentage of parasitism. 
The maggots live within the host, located in typical integumental 
funnels. The anal stigmata of the puparia are highly raised with 
the dorsal surface reticulated. A series of the reared specimens 
compared with the type of the species in the United States National 
Museum, appear identical with the specimen described by Coquil- 
lett. To my knowledge, this is the first record of this genus hav- 
ing been reared in North America although Brauer and Bergen- 
stamm? record the rearing of the genotype, Pelatachina tibialis 
Fall. from Vanessa urtice Linn. in Europe. 
Compsilura concinnata Meig. 
Since the introduction of this species from Europe and the 
establishing of it in the United States, by the United States Bureau 
of Entomology, as one of the foremost primary parasites of Por- 
thetria dispar Linn. and Euproctis chrysorrhea Linn., it is known to 
have been reared from more than twenty species of native North 
American Lepidoptera. In the study of reared Tachinide from 
various New England sources, it has been noted that this species 
is particularly prolific as a parasite of Euvanessa antiopa Linn. 
In certain instances of its parasitism upon this host in the New
