CURRENT NOTES. 205 



antennal segments in the instars of a Hawaiian earwig is not the 

 same as in the common British form (30) ; the data in the latter 

 case are, however, fragmentary and apparently inaccurate. 

 Siltala discusses the parasites of Trichoptera (26). 



Oshanin has commenced (15) a catalogue, with references, 

 synonymy, &c., of the palfearctic Hemiptera, including Japan, 

 &c. The first part of the first volume deals with Cimicidae, 

 Lygseidse, Pyrrhocorid?e, Geocoridfe ; the first part of the second 

 with the Cicadoidea. For these groups Oshanin records 1335 

 and 784 species respectively. Puton in 1889 admitted 1011 and 

 730, but he excluded China and Japan. 



Kirkaldy summarizes (11) Eeuter's recent classification of the 

 Miridffi, and translates the analytical key of the divisions, as well 

 as making numerous additions and corrections to his own recent 

 nomenclatorial paper on the Hemiptera. 



Marlatt has brought Bulletin 12 of the same series up to date 

 (14), discussing the Coccid Aspidiotus perniciosus. 



Fuller remarks on the supposed poisonous properties of 

 "bagworms" (Psychidae) (7). Schultz discusses certain palse- 

 arctic gynandromorphous Macro-Lepidoptera (23). Willem 

 makes an observation additional to the recent ones of Plateau 

 on Macroglossa (32). Swezey details the Hfe-history in Hawaii 

 (29) of Plusia chalcites, Spodoptera exigua, and S. mauritia ; as 

 the second is found in the British Isles his paper will be of 

 interest to British lepidopterists. 



Schuster deals biologically (24) with several species of Crio- 

 ceris, and Xambeu (36) with Silpha. Gaulle has commenced (8) 

 a systematic and biological catalogue of French Hymenoptera. 



White describes certain bee-diseases (31). Girault details 

 the oviposition of the Chalcidid Trichogramma (or Chatostricha) 

 pretiosa, parasitic on the sawfly Pteronus (or Nematns) ribesii. 

 The sawfly is common to Europe and North America, but the 

 parasite has only been recorded from the latter so far, though 

 other species of the genus are European (9). Pdley briefly sum- 

 marises (22) Silvestri's recent biologic work on Litomastix. 



Williston criticizes the methods of certain recent workers on 

 Culicids (34), and corrects some common errors in the nomencla- 

 ture of the dipterous wing (33). Dyar and Knab (5) describe a 

 large number of Culicid larvse, many being treated as new species 

 independently of the adults. In an editorial, Dyar declares 

 (p. 231) that the date of this paper is March 14th, 1906, authors' 

 separata having been distributed on that date. The correct date, 

 however, is December, the journal having been issued apparently 

 during that month. Gossard and Houser bring forward some 

 fresh facts relative to the life-history of the Hessian Fly (10). 

 Ainslie has some notes on the swarming of the Tipulid Tricliocera 

 himacida (!). Eiley mentions the case of larvae of a Sarcophaga 

 in a tumour in the back of a woman (21). L6caillon reviews
