INSECTA HYMENOPTERA. 173 



the author, however, shows, very satisfactorily from the descriptions, partly of 

 Linnaeus, and partly of Hasselquist, the discoverer of this insect, that the 

 insect of the (Egyptian) Sycomore, the Sycophaya crassipes, Westw., is uotliiug 

 but the Cy>i. Sycomori, L.; but that the insect of the (South European) edible 

 Eig is the Blastophaga grossorum, Gr., the tme C. Psenes, L. ; aud consequently 

 that the former should be termed Sycophaga Sycomori, and the latter, Blas- 

 topliaga Psenes. 



PROCTOTRTJPII. The genera, Pelecinus and MonomacJms are both eluci- 

 dated by Westwood, in his work on Evania (v. s.) ; the former at present 

 includes eight species, the second seven, of which, however, only three are 

 described by the author ; the fourth, M.fuscator, is taken from Pcrty ; the 

 other three, (together with the first two from the Berlin Collection,) are 

 only mentioned by name. All these species are South American. The 

 Berlin Collection has also received some species lately from New Holland. 



Some new Oxyuri, have been described by Walker, together with the Chal- 

 cidites : Telenomus Apitius, from St. Vincent's Isle (Ann. Nat. Hist, xii, 

 p. 48) ; Platygaster Sylea, from Coqui.mbo ; and Qmaloderus intrepidus 

 (Hal., MS.), from the same place. (Ib. xi, p. 188.) The latter new genus is 

 indicated as being allied to Betliylus, and has in the fore wings 3 cubital 

 and 2 subcubital areolse. 



CHKYSIDIDES. Two new Spanish species are, Chrysis crassimargo, and 

 IlcdycJirum aulicum, Spinola (1. c.) ; the latter is distinguished from all the 

 other species by an elevated longitudinal line down the three abdominal 

 segments. 



SPHECIDJE. Dahlboni (Hym. Europ. p. 1-29) has enriched this family 

 with a number of new extra-European species, and has proposed at the 

 same time some new genera, which were not given in his ' Conspectus,' but 

 upon which, as the characters are not here added, I can say nothing more 

 particular. 



Under Chalybion the blue coloured JWo^^,? are separated, as Peps, violacea, 

 E., and Sph. cycmea, L. Another genus, Enodia, is erroneously attributed to 

 the Encyclopedic Methodique ; it was instituted in the Berlin Collection, 

 and separated from Sphex on account of the horny labruni, emargiuate in 

 the centre, like the nientuin of the Carabidse. Of the two species enu- 

 merated by the author in this genus, Sphex albisecta, Euc., is for this 

 reason placed by us under Enodia, and E. canescens, Dahlb. (but which is 

 Peps, pubescens, E.), under Sphex. On the other hand, we have included 

 under Enodia, Peps. Thomee, E., of which the author forms a distinct genus, 

 Prianonyx. With regard to the new species of the author, since his 

 book will infallibly be in the hands of every one who is occupied with 

 this order, a few remarks only will be given. Hiscus arvensis, from North 

 America, is by us placed with Ammophila, because all our specimens have the
