tlie whole segment. Palpi pale jelluAvish, Aery shoil, scarcely one-third as long- 

 as the vertical diameter of the head ; palpiger (or perhaps the first palpal seg- 

 ment) sub-glohular, first (or second ?) segment oval, second (or third ?) segment 

 elongate-oval, about half as long again as the first, each segment with four or 

 five short bristles. Labella short, shorter than the palpi, each with one or two 

 sub-apical bristles. Hypopharynx in c? lather broad and pubescent, in § 

 narrower and bare, llwrax shining dark brown ; membranous parts dark 

 reddish in life. Mesonotum with the usual two rows of long black bristly 

 hair ; similar hair on the margins ; scutellum paler than the rest of the thorax, 

 with long dark marginal bristles. Abdomen rather short and broad, with dark, 

 reddish membrane, tergites blackish-brown ; clothed rather densely with black 

 hair. Leys uniformly clothed with black hair-like scales. Wint/s scarcely 

 twice as long as broad, with dense blacli close-lying hairs and rather long black 

 fringes. One pore near the base of the feebly-marked iSc, two at the tip of Hi, 

 and one on Hs at a point half-waj' between the base and tip of JR^. Salteres 

 pale at the base, knob black. Wing-length about 2 mm.

The broadly oval shape of the larvae and pupae is peculiar, but not 

 unique among the Cecidomyiidae. Somewhat similar larvae and pupae 

 have been described by Riibsaam^en for ^hahdoioliaga pseudococcus, a 

 species which forms white cocoons on the under sides of sallow leaves. 

 I have myself found larvae not at all unlike those described above, 

 feeding openly on a fungus (a species of Corticium'^) encrusting a fallen 

 log ; in this case I failed to rear the larvae and did not preserve any.

Choleva angiiatata F., and its allies : supplementary note. — Dr. R. Jeanne 

 in a recent paper entitled " Sur les Choleva des iles Britauniques " (Bull. Soc. 

 Ent. Fr. 1922, pp. 49, '50) comments upon the five species of the genus charac- 

 terized and figured by me in this Magazine in 1918, pp. 80-33, figs. 1-6. He 

 accepts all of them as distinct, two being unknown to him on the Continent, 

 and makes various corrections in the synonymy, concluding with the remark 

 that C. angustata Fabr., C. cisteloides FriJl., and C. sturmi Bris. are not found 

 in Britain ! He appears to have overlooked the fact that the type of C. ( Cistela) 

 angustata Fabr. (Sp. Ins. i. p. 148, 1781) was from "Anglia," and that it is 

 contained in the Banksian Collection at the British Museum in London. I was 

 also unaware of this when my paper was written, and now find that my identi- 

 fication of the species was incorrect, thus misleading Dr. Jeannel. Mr. Blair, 

 in 1920, in his " Further Notes on P'abrician types in the Banks Collection " 

 (Ann. and Mag. Nat. Hist. (9) v. p. 162) states that C. angustata F. appears to 

 be the C. sturmi of Continental entomologists, but this is evidently not the case. 

 He and Mr. Champion have been kind enough to compare my 1918 material 

 with the Fabriciau type, a S , still in a fair state of preservation, and it work s
