contains the Ralicti of the tropics ; it is from Brazil, is about seven 

 lines long, and of an uniform brownish-black, with brown wings ; its 

 intermediate femora are enormously swollen, and compressed into a 

 semi-dentate process beneath ; the posterior tibiae are also very 

 curiously developed, and compressed into a large sub-triangular mass, 

 with a tooth at its inferior angle ; altogether, it is a bee of remarkable 

 form ; but, instead of possessing antennae resembling those of a butter- 

 fly, they are exactly the counterpart of tJiose of several of the males of 

 species of the genus Megachile, which have antennae of the ordinary type 

 of form, excepting the apical joint, which, as Mr. Kii'by remarks, " is 

 compressed," which gives them some resemblance to those of a Fapilio; 

 the species is named Nomia Kirhii. 



It is a matter of satisfaction to feel assured that one's memory is 

 not quite so treacherous as I began to fear it was becoming, for the 

 monograph of the genus Nomia, in which Mr. Westwood described 

 N. Eirbii, although certainly begun ten years ago, has not yet been 

 published ; it is satisfactory also to find that I have not been so 

 negligent of the laboui's of a brother Hymenopterist as I feared I 

 might have been ; and, also, that it will not be necessary to make any 

 alteration to the introductory remarks to the paper on Australian 

 Hymenoptera, which I had the honour of reading at the last meeting of 

 the Entomological Society. 



OBSERVATIONS ON THE LARVA OF DEILEPHILA. 

 BY J. BOSWELL SYME, F.L.S. 



If, as our best authorities tell us, a severe winter be favourable to 

 the development of insect life, we may, this season, hope for a larger 

 list of captures than that which has been afforded by the few last 

 summers : and to hear of the re-appearance of some of the rarities 

 which gladdened our hearts in years gone by. Among the Lepidoptera 

 of which we have had to lament the disappearance, one of the most 

 conspicuous is Deilephila galii, of which it was my good fortune to 

 procure numerous specimens during the years 1856 — 1S62 ; and, in 

 the hope of its re-appearance, I now propose to say a few words on its 

 habits, which I trust may prove useful to those who may be on the 

 look out for the larva of this handsome moth ; and which may also 

 possibly furnish hints to those who may find themselves in localities 

 where the lost D. euphorhice might be expected to occur. That this 

 latter has not been recently found is no proof that it is really extinct,
