characters on which they are founded are relegated to their proper 

 place of subordination. Professor Blanchard's book is really a mine 

 of information about mosquitoes. We only regret that he did not print 

 his own synoptic tables and classification, which were prepared at much 

 pains as he tells us, but thrown in the waste basket on seeing Theo- 

 bald's book, in an access of enthusiasm, scarcely deserved, we fear. 

 " Les Moustiques " should be in the hands of every student of mos- 

 quitoes. 



A Monograph of the Anopheles Mosquitoes of India. By S. P. James, 

 M.B., I. M.S., and W. Glen Liston, M.D., I. M.S. Calcutta, 

 1904. 



The authors find twenty-four species of Anopiicles in India, of 

 which they know the larvae of eighteen. The adults are figured on a 

 green background, which relieves the white scales beautifully and gives 

 a very fine effect. The species should be easily recognized. Ten of 

 the larva; are figured. The larvae all differ from the American spe- 

 cies in the greater development of the fan-shaped dorsal tufts, which 

 are present on the second abdominal segment in all cases and in many 

 also on the first abdominal and on the metathorax. The larvae must 

 therefore have even a closer connection with the surface film of the 

 water than is the case with our species. Most of the species have 

 the front of the head triangularly produced and the antenna; much 

 thickened, though some are more rounded like our species. A. barbi- 

 rostris Van der YVulp is nearest in aspect to ours. The species are 

 divided into two groups : first, with the antennal tuft branched (as in 

 our species), containing three species; second, antenme without 

 branched hair, containing fifteen species. The first group is sub- 

 divided by the frontal hairs being simple or branched ; the second by 

 the presence or absence of the fan-shaped tuft on the thorax. The 

 details of the frontal hairs and the fan-shaped tufts are used to separate 

 the species. Six types of Anopiicles eggs are shown (p. 39), which 

 differ remarkably in the development and position of the "floats." 

 This structure is present in all, though in A. turkhudi Liston it is re- 

 duced to a little dorsal ellipse near one pole of the egg. The authors 

 reject Theobald's genera of the Anophelinae founded on scale char- 

 acters (with their reasons for rejection given in detail) and place 

 all the species in Anopiicles. They nevertheless divide them into ten 

 groups on general affinity, but without any very sharp diagnostic char- 

 acters.
