170 REPORT ON ZOOLOGY, MDCCCXLIII. 



T. blanda, L. ; and T. Grossularice, from the description, is, iu my opinion, 

 doubtful, from the appellation probably only a variety of T. (Nematus) 

 Ribesii, Schr. (ventricosus, KL, Hart.) 



UROCERATA. Spinolahas published a Memoir, which was produced before 

 the Scientific Congress at Padua, entitled, ' Cousiderazioui sopra i costumi 

 degl' Imenotteri del g. Sirex F., e sopra il miglior posto dei Sireceti nel 

 methodo razionale, Genova, 1843 ;' in which he supports the opinion lately 

 propounded by Lepelletier de St. Fargeau, that the Wood Wasps are parasitic, 

 in the same way as the Ichneumons, by ail instance in which a Sirex gigas is 

 stated to have come out of the pupa of Papilio macliaon. The author, how- 

 ever, does not agree with Lepelletier in separating the Wood Wasps from the 

 Saw Mies and associating them with the Ichneumons ; and he is the more 

 correct in this, as it has been sufficiently ascertained in this country, that the 

 Sirex-larva; themselves bore into the wood; and the observation related above 

 must be founded in some error. 



ICHNEUMONIDES. Blackwall (Report of the Twelfth Meeting of the Brit. 

 Association, held in Manchester, 1842, p. 68 ; in more detail, Ann. Nat. 

 Hist, xi, p. 1 ; Fror. N. Notiz. 25 B. s. 113) has given an account of the 

 larva of an Ichneumon, which is met with externally, on the upper part of 

 the abdomen of several spiders, particularly of Epe'ira antruida, aud cucur- 

 bitina, c. From this larva he bred an Ichneumon, which Stevens deter- 

 mined to be Polysphinda carbonaria, Gr. When the Ichneumon larva had 

 quitted the Spider, for the purpose of spinning its cocoon on the cork 

 of the bottle in which it had been contained, the Spider died. The latter 

 was immature, and it was a remarkable circumstance that it did not cast its 

 skin. 



As new Spanish Ichneumons, Spiuola has described (1. c.), Bassits hispani- 

 cus, Pimpla Glill/aiiii, Cryptw andalwicus, Ichneumon melanopterus, nigricornis, 

 baticits, en/tlirurits, nnifasciatus. 



BRACONIDES. From the same country are, Bracon bat'tcxs, bicolorator, 

 Agathis bcetica, Spiuola (L c.) The latter is Ag. emu, KL, in Waltl's ' Reise.' 

 An undetermined Braconid, bred out of Ccdlidium tang-tineum, has been 

 described by Goureau. (Ib. p. 104, tab. iv.) 



EVANIALES. Westwood's Memoir on ' Ecaiiia, and some allied genera of 

 Hymenopterous Insects,' already noticed (Report for 1841, p. 267), has 

 now appeared in the 'Transact, of the Ent. Soc. of London,' and illustrated 

 with numerous figures. The genus Ecania, in the present enumeration, 

 contains thirty species, among which is one new, E. antennalis, W., from 

 Bombay. Fanus has received an accession in I'.gracillimus, from Demerara 

 and Spain is assigned as the native locality for>. clorsalis. Aulacus,^, 

 has acquired a new species, A. congener, locality unknown. 



Some remarks on Ecaiiia, have been made by Guerin. (Rev. Zool. p. 333 )
