to need separate tribes, for the wealth of these forms and the 

 variety of type exhibited by them are but little realized as yet. 



Ceromasia ruftpes B. B. is also included and stated to have 

 a very small black egg, long uterus, and numerous ovarioles. 

 It is certainly not Ceromasia, as the genotype, Ceromasia 

 florum, has deep yellow eggs of good size. I propose the new 

 genus Ceromasiops in this paper for its reception. Moreover, 

 Ceromasiops rujipes is recorded as reared from forficulids, 

 which causes Pantel to question whether the microtype eggs 

 are always deposited on foliage. No doubt a reservation must 

 be made in this respect, but it is quite safe to conclude that 

 they are normally deposited on the food. The investigation 

 of the host relations of Ceromasiops promises to be unusually 

 interesting. But it must be observed that forficulids are not 

 uniformly carnivorous and refuse-feeding. A species has been 

 reported in Tasmania as extremely abundant eating into ripe 

 fruits, and others have been found eating the buds of plants. 



Brauer's record of Gonia parasitic in bees is based, I be- 

 lieve, un Zetterstedt's original record. Gonia has been reared 

 in numerous cases in North America from noctuids. The 

 Zetterstedt record may perhaps have been due to infested 

 noctuid caterpillars crawling into Bombus nests to pupate. I 

 have not seen the original record. 



As to Spallanzania hebes having been reported viviparous 

 by Dufour, it may exceptionally happen that a fly should con- 

 tain in the lower part of the uterus overripe eggs, so to speak, 

 or maggots in choria that have been carried overtime, from 

 lack of finding suitable places for oviposition, and which may 

 burst from their choria on the least provocation. The mere 

 handling of the fly may cause this. I have noted the mag- 

 gots burst from the choria during dissection of dried speci- 

 mens of Blcpharipeza and Gonia that have been relaxed, 

 merely as the result of the mechanical effects of manipulation. 



A most important point abundantly brought out in Pantel' s 

 work is the fact that the female reproductive system in the 

 forms with uterus exhibits very different characters before and 

 after the descent of the eggs. Many forms which possess a 

 very long, coiled uterus at the full stage of gravidity show 

 the uterus practically undeveloped at time of issuance from 

 the puparium and until the descent of eggs from the ovaries 

 has become well inaugurated. This may apparentlv go so far 

 as to be very misleading, as I have shown with Gonia, pro- 

 vided I have not confused two distinct forms, individuals with 

 a short uterus containing fully developed maggots. The one 

 type shows a short uterus in only one or two coils, with very
