INSECTA — HYMENOPTERA.

torim, licitatorius, promissorius, Cryptus {Phygadeuon) variegator, 
Ophion fuscicornis. The first species only has any peculiarity, and as 
at present several allied species are before me, will give occasion for the 
formation of a separate genus belonging to New Holland. The rest 
have altogether a European stamp. 
Braconid^. — Schiodte (Kroyer Naturhist. Tidsskr. iv. p. 315) has 
remarked, that Lepton attenuator, Zetterstedt, Ins. Lappon., is the 
insect described by him (1837) as Copisura rimator. Zetterstedt did 
not know the female, his description appears to apply at a Coelinius. 
(See my Report for 1838, p. 296.) 
Helcon indultor of the reporter is a new species from Van Diemen’s 
Land (Arch. 184:2, i. p. 258). 
Evanid^. — Spinola (Rev. Zool. p. 188) has described three new spe- 
cies of Evanioj : facialis from Mexico, chilensis from Chili, crassicor- 
nis from Columbia. 
The reporter has described a new species of Megalyra : rufipes, from 
Van Diemen’s Land (Arch. 184:2, i. p. 258). 
Cynipid^. — Hartig (Germ. Zeitschr. iv. p. 395) has published his 
farther investigations into the natural history of the Cynips. Although 
he withdraws his former assertions (see the preceding annual report) 
concerning the internal structure of the male Cynips, still he draws atten- 
tion to this family in a physiological respect, by showing that the males 
of some species are unknown ; such are, especially, Cynips divisa and 
C. quercus-folii,* which he obtained in great numbers, partly from galls 
and partly caught in the open air ; he also remarks, that in the breed- 
ing of Cynips from galls, the absence of the male cannot be accidental ; 
that moreover, whole genera {e. g. Cynips with twenty-eight species) are 
without males, while in the rest {e. g. Aulax and Synergus) both sexes 
of all the species are found ; and thinks, that from the comparison of the 
internal structure of the one, and both-sexed Cynipidce, something more 
certain will be discovered. Siebold is at present busy with these inves- 
tigations, so that we may shortly expect a solution from that quarter ; 
however, it appears to me, that he should not neglect these so called 
Inquilini. Hartig has certainly expressed, in his first treatise (Germ. 
Zeitschr. ii. p. 178), that they not only live parasitically in and on 
strange galls, but also on their proper inhabitants ; he has not however 
added, that this is nothing more than conjecture. The constant presence 
of two forms of Cynips, in all galls, is striking, and might easily lead to 
the supposition, first made by Ratzeburg (Mediz. Zool. pt. ii. t. 21), that 
a compound sexual relation here occurs, as is also the case in other orders 
* The author mentions, that Professor Ratzeburg had told him, that he was 
in possession of a male of this species. Upon farther examination, the Pro- 
fessor has informed me, that he is now convinced of the contrary.
