femora above, the four posterior broadly above and below to near the 

 apex, a line on the centre of the fore tibiae before and behind, and on 

 the four posterior, black. Wiugs hyaline ; the costa and basal ner- 

 vures testaceous, the others darker. <^ . Length, 17 mm. 



Hah, Darjeeling. 



Head and thorax thickly covered with white longish pubescence ; 

 the first transverse cubital nervure is largely dilated backwards below ; 

 on the second ventral segment is a large tooth, which commences near 

 the base and extends to the apex ; it is roundly broadly curved, and 

 becomes narrowed towards the. apex below; the apical part is also 

 roundly curved ; the sixth segment is broadly raised in the middle ; 

 this raised part becomes narrowed towards the apex, which is rounded, 

 and has there an oblique slope. The last segment is punctured, except 

 in the centre, where there is a smooth shining band ; it becomes 

 gradually narrowed towards the apex, the sides being only indistinctly 

 curved. The basal joint of the front tarsi is stout, and is longer than 

 the three following united ; the spines are long, pale, and moderately 

 stout ; the middle femora are irregularly toothed ; the teeth are more 

 numerous on the basal half. Eyes almost parallel, only very slightly 

 divergent below. Front keeled. The yellow bands on the abdomen 

 are sulphur-yellow on the base, paler on the apex. 



In Bingham's arrangement, the species would come, in his 

 table, close to B.pinguis and B.fossoria. Characteristic is the 

 very large tooth on the second ventral segment. 



NOTES AND OBSERVATIONS. 



The Tuberclks of Saturnia carpini. — Keferring to Mr. Lucas's 

 note respecting the colour of the tubercles in larvfe of S. carpini {ante, 

 p. 240), I may mention that a half-grown larva of this species was 

 brought to me about six weeks ago, having bright crimson tubercles. 

 After having kept it a week or so, it changed its skin, and also the 

 colour of its tubercles, which were dull orange from then up to the 

 time of its death, which occurred when quite full-grown. — G. F. Lyle; 

 Brockenhurst, Sept. 12th, 1904. 



Larvae of Arctia caia swarming in the Scilly Islands. — During 

 my stay m the Scilly Islands from the middle of May to the middle of 

 June last, all the larger islands were teeming with thousands of the 

 larvas of A. caia. They swarmed in such myriads that no vegetation 

 escaped them — they fed on any green stuff available from stonecrop to 

 shrubs of various kinds. Bracken seemed in great demand, also various 

 other ferns, kc. Every path and roadway was dotted all over with their 

 crushed bodies. — F. W. Frohawk. 



Aporia cratvEgi ab. — During last July I found the headquarters of 

 a batch of imagos of Aporia cratcctji, and captured twenty specimens. 

 There were no varieties, but one of them turned out to be a little bit 

 of a freak, for the hind margins of each wing had two curves instead 

 of one. At first I thought it was a crippled specimen, but it proved
