very similar in appearance and liabits, attack stock of all kinds, but 

 have not been observed attacking man. T. inipressus, Wied., is a 

 widely distributed species which is known to attack man. Only one 

 specimen of T. un/ponens, Wlk., has been ca])tured. The feeding 

 habits of T. desertus have never been observed, though numbers of 

 this fly have been collected and the larvae and pupae have also been 

 obtained. T. caiennensis, F., is an occasional pest of stock on 

 the coast-lands and is also common in some parts of the interior 

 where it readily attacks man. T. leucaspis, Wied., which also 

 attacks human beings, is of rare occurrence in the forest area. T. ocliro- 

 leucus, Mg., is frequently taken in houses at light and has been known 

 to attack man. One specimen of T. oculus, Wlk., was taken in the 

 interior districts while attacking man. A number of Hippoboscid 

 flies are known to infest birds, including Lynchia manra. Big., common 

 on domestic pigeons. The burrowing flea, Dennatophilus penetrans, L., 

 is widely distributed over the Colony, while Cienocephalus felis, Bch. is 

 probably the commonest flea on the coastlands on dogs and cats ; it 

 occasionally attacks man. The common bed-bug of British Guiana is 

 Cimex hemipiera, F. {roUmdatvs, Sign.). Pediculus capitis, de G., 

 infests negroes. East Indians, etc. P. humanus, L., has been found 

 only on East Indians, while Phthirius pubis, L., infests all the different 

 races inhabiting British CJuiana. Haematopinus eimjsternus, N., 

 is the common cattle-louse, while H. tuberculaius, N., has been 

 collected only on imported Indian buftaloes. H. suis, L., is very 

 common on pigs.

A description is given of Phlebotomus major var. chinensis, var. n., 

 from the Western Hills, Peking, with a note on another, possibly new 

 species of this genus from the same locality [see this Review, Ser. B, 

 iii, p. 113].

The new species here described were collected in the region of the 

 Sierra Nevada Mountains and are all spring forms, breeding in pools 

 left by melting snows, and having one annual generation. At an 

 altitude of 6,000 feet, pupae were found on 25th May and adults 

 appeared by 1 st June. The new species described include : — Aedes 

 tahoensis, A. hexodontus, A. venfrovittis, A. cataphylla, A. increpitns, 

 A. palustris. A. tahoensis was the commonest and earliest species, 

 adults being abundant by the middle of June. Towards the end of 

 June it was replaced to a considerable degree by A. hexodontus. The 

 latter, together with A. palustris, occurred in the larval stage mainly 

 in sw^ampy ground. With the exception of A. hexodontus and 

 A. palustris, the females were found to bite readily.
