It seems hardly possible that Alophora and Ilcmvda can 

 belong to the same subfamily. I believe that Alophora is to 

 be grouped with Phasia in the Phasiinae, notwithstanding the 

 very diverse reproductive characters of the two. llcnivda 

 and Cercomvia I consider members of the subfamily 

 Phauiinae, in which I am also inclined to include Compsilura 

 and its allies. All three, however, have certainly much 

 affinity with the pseudode*.iineand pyrrhosiine types, which I 

 unite in the subfamily Pseudodexiinae. 



(ironp X. Species depositing on the host a pediceled egg 

 in which the maggot is already well developed. The author 

 cites Parexorista chelonicp as the sole representative. Niel- 

 sen has shown in his last paper (1911) that Carcelia has the 

 same egg. Pantel considers both species as C arcelia, but it 

 seems to me that chelonicc is generically distinct on adult 

 characters if not on others. 



This group I consider as forming a tribe of the subfamily 

 Hemimasiceratinae. 



It seems quite certain that normally the egg is not deposited 

 until the maggot is well advanced in development, as with 

 Gastrophilus and Hyppdenna among pediceled-egg forms 

 and Meigcnia and Thrixion among flat-egg forms. But we 

 noted positively at the Gipsy Moth Laboratory that both 

 Parexorista chelonice and Carcelia giiaz'a deposited unde- 

 veloped eggs, which I must consider exceptional. 



A number of species of uncertain reference are mentioned 

 by Pantel, which are of interest. They are as follows: 



Ceromasia flomm the author thinks may belong with 

 Blepharidea in his Group VI. He had only undeveloped 

 females for dissection. A dried specimen dissected by me, 

 determined as this species by Brauer and von Bergenstamtn, 

 showed yellow microtype eggs. It thus belongs in Pantel's 

 Group II, with the leaf-ovipositing forms. 



/sxorisln westermanni the author believes to possess a 

 microtype egg, and to have similar characters to Fronlimi. I 

 hope that someone will soon dissect the type species, criuita 

 Rdi., and thus establish the status of the genus I^xori$ta. I 

 have found the most widely divergent reproductive characters 

 flattened- oval macrotype eggs deposited on host, microtype 

 eggs deposited on leaves, elongate maggots developing in 

 uterus and deposited naked or in choria on or near host in 

 specimens which possess the external characters ordinarily 

 considered as defining the genus l^xorista. Phoroccra simi- 

 larly needs establishing on its type species cilipcda Rdi.,
