Mr. S. K. Sen publishes a preliminary note on the role of 
blood in ovulation in Culicidae. The first paper by Mr. C. H. T. 
Townsend on the true muscids in the Indian Museum has just 
appeared, and others will follow in due course. As the leading 
living authority on the higher Muscidae his papers will be 
eagerly looked forward to. Mr. F. V. Theobald’s writings on 
Culicidae are too well known to need mention or praise here, 
for although a good proportion of his species have since been de- 
clared invalid, much remains of his laborious monographic work 
which will always stand to his name as a pioneer in this Family. 
s regards my own work I can only briefly note having 
compiled papers on the Stratiomyidae (a second in preparation), 
Syrphidae (two), Leptidae and Bombyllidae (three), Empidae, 
blood-sucking Muscidae, Sepsinae, Tipulidae (a second just pub- 
lished), Psychodidae, Nemocera (certain families only) and general 
papers on ‘“ New Oriental Diptera,” ‘‘ Diptera of the Abor Ex- 
pedition,” ‘‘New and interesting diptera from the Eastern 
Himalayas,” and ‘‘ Diptera of the Simla District.’’ Also a Cata- 
logue of Oriental Culicidae, with a Supplement and a Critical 
Review of genera in Culicidae. 
first volume on diptera in the “ Fauna of British India” 
series appeared in December 1912, containing all the Nemo- 
cera except Cecidomyidae, Chironomidae and Culicidae, ovet 
two hundred and fifty new species being described in it. A 
second volume, treating of certain families of Brachycera and 
Cyclorrhapha is in preparation. A Catalogue of the Oriental 
Nemocera is in hand and approaching completion. 
Comparative notes with our knowledge of 1896 may now 
be given under each family.! : 
Cecidomyidae.—Of gall gnats only three species appear In 
Van der Wulp, but about 30 are now known, mostly described 
by Kieffer. Some knowledge of botany being requisite for 
successful work in this family may be the reason why so few 
dipterologists have concerned themselves with it. The species

subject (see footnote 1) may be referred to. It is impossible to give here 
references to all the new species described since Van der Wulp’s Catalogue

one or two minor exceptions, are published in the Rec. Ind. Mus. from 
1908 onwards.

various groups appear from time to time in the ‘‘ Nova Guinea Results.
