368 REPORT ON ZOOLOGY, MDCCCXLIV. 



Walk.), Siphonnra (= Ormyrm, Westw.) 2, differing, perhaps, as varieties 

 merely of Orm. pnnctiger, Westw., Platymesopus 2 (but PL westwoodii, E,., 

 is identical with tiUalis, Westw., and PL erichsonii, R., probably no more 

 than a variety of the same), Pteromalus 48 (the genus is taken in the wider 

 sense, embracing many modern genera), Enpelmus 1, Encyrtus 2, Elacliestus 

 1 (an Entedon, Walk.), and EulopJms 26 (another of the groups requiring 

 subdivision ; No. 10, K flavomaculatus, is, perhaps, Cirrospilus elegantissi- 

 mus, Westw., while Nos. 19-33 belong to the genus Tetrastiches.}] 



Von Heydeu (Eut. Zeit. 205) has noticed a species parasitical on Caenia 

 halophila (see further on), under the name of Pteromalussalinus. It is pro- 

 bably Urolepis maritimm, Walk. (Chalc. Brit. Mus. 26, == Ormocems id., W., 

 Ent. Mag. ii, 169 ; Entomologist, pi. E, f. 4), which is known to infest the 

 pupa of Ephydra riparia in like manner. 



[Curtis has described Pteromalus micans (R. Agr. Soc. Journ. v, pi. L, 

 fig. 37, Chalcis id., Oliv.), which is a common parasite of Chlorops liueata and 

 tEeuiopus. It is the same as Pter. bellus, Walk.] 



Walker (Ann. Nat. Hist, xiv, 14) has described a number of species from 

 North America: Callimome splendidus, cecidomyice, Lamprotatus dibits, Encyr- 

 tus bolus, Tetrasticlius granulatus ; and again (p. 18, 181), several found in 

 Britain : Eurytoma tumida, argele, sittace, scultenna, micipsa, Isosoma nepe, 

 Decatoma nicea, Callimome rasaces, cerope, Pteromalus domesticus (bred out 

 of caterpillars of Lozotsenia sylosteana), Encyrtus epona, euryclea, pyttalus, 

 Aphelinus acates. Tetrastichus rapo, Walk., has been bred out of the 

 cocoons of Microgaster glorneratus, a parasite of Poutia brassicse ; Encyrtus 

 maclweras, from the Coccus of the elm ; Encyrtus paralia is a variety of E. 

 argentifer. 



He has also enumerated (ibid. p. 331, 407) some Pteromalina of the north, 

 which he collected at Hammerfest and at Alten in Pinmark. The following 

 are new species : Euneura aut/arus, Lamprotatus pldegias, mazceus, brises, cleta, 

 sccea, leucon, lesches, icelos, Seladerma mazares, saurm, Gastrancistrus puna- 

 res, Pteromalus jera, musams, pyttalus, rliintlwn, mazaces, Encyrtus cleone, 

 Horismenus climts, Tetrastichus idotJiea, EulopJms idrieus. The new genus 

 Euneura comes next to Corona. 



[SPHEGIDES. Curtis (Gard. Chron. 731) has given a more particular 

 account, with figures, of the transformation of Ammopldla salulosa. (See 

 Deg. ii, Mem. 14 ; Bouche Gartenins. 157.) A single egg was deposited 

 on a caterpillar, probably of a Noctua, buried in a cell, about two inches 

 deep in the earth, and very artfully closed. By the ninth day the caterpillar 

 was entirely consumed. The grub changed to a nymph within an oval 

 cocoon of membranous texture. The wasp came forth in about six weeks 

 after.] 



THYNNIDES. Westwood (Arc. Ent. pi. 74, 75, 76, 77, 82, 83) has sig-
