150 Records of the Indian Miiseum. [Vol. VIII, 



BIBIONIDAE. 



PIcciomyia melanaspiSt Wied. 



Six specimens altogether, from Dibrugarh, 17 — 19-xi-ii; be- 

 tween Kalek and Missliing (4500 ft.), i7-iii-i2, Kalek (2300 ft.), 

 i5-iii-i2. It is common in Abor villages. 



Bibio obscuripennis, Meij. 



A headless example from Rotung, 25-xii-ri (on the sand banks 

 of the Dihang River), is in all probability this species.. In this 

 specimen the 3rd vein forks immediately over the anterior cross- 

 vein ; this is abnormal, as it usually forks very distinctly before it. 



SIMULIIDAE. 



Simuliutn ? indicum, Becher. 



There are three specimens of a Simulmm, of which at least 

 one is likely to be indicum, Becher, but they are much too worn 

 to identify with precision. The one in the best condition is from 

 Rotung (23-xii-ii), the others from Rotung (24-xii-ii) and Upper 

 Rotung (6-i-i2). One bears the laconic note '^ bites." 



CHIRONOMIDAE. 

 Calyptopogon albitarsis, Kief. 



One specimen (17 — 19-xi-ii) from Dibrugarh. 



Kieffer (Mem. Ind. Mus. ii, p. 210) comments on Meijere's note 

 (Tijd. v. Ent. 1, 216) on a specimen from Java which he identified 

 with Macropeza gihhosa, Wied, saying that as that author said 

 nothing about the form of the thorax, he (Kieffer) concludes that 

 it is shaped as in the European (type) species of Macropeza, Mg. 

 {albitarsis, Mg.): that is to sa}' without the conspicuous projection 

 over the head which characterizes Wiedemann's species. 



But as it seems impossible that Meijere could have avoided 

 reading Wiedemann's very distinct statement, " thorace antice supra 

 caput producta," it must be assumed that he correctly identified 

 the older author's species, though possibly considering a new 

 genus for it unnecessary. If this be the case, Kieffer 's )ioni. nov. 

 {Macropeza javanenis) for the species identified by Meijere as 

 gibhosa, Wied. will sink as synonymous. The erection of a new 

 genus for gibbosa seems quite just. 



C. albitarsis differs from gibbosa by the hind metatarsus being 

 twice as long as the corresponding tibia; whilst, according to Meijere 

 it is "longer" than the tibia in gibbosa. It seems to me the 

 relative lengths of the tarsal joints are not alwa3's consistent. 

 Although the present specimen is referred to this species, the hind 

 metatarus is only a little more than one and a half times as long 

 as the hind tibia, and in two other specimens of the same species' 

 in the Indian Museum from South India (Kerumaadi, at the south 

 end of Vembanaad Lake, Travancore (6-xi-o8) and Trivandrum
