lectularius, L., en tot zijne Bestrijding. [A Contribution to the 



Biology of Cimex lectularius and to its Control.] — Teysmannia, 



Batavia, xxx, no. 1, 1919, pp. 12-30, 1 plate. 



The species of bed-bug found in the Dutch East Indies is illustrated, 



and is beheved to be Cimex lectularius * the identity and synonomy of 



which is discussed. It is seldom found permanpritly in the stone houses 



of Europeans, but occurs in the wooden dwelhngs of the natives and 



also in hotels, etc. The presence of these insects causes no concern to 



the natives, who appear to be immune to the efiects of their bites, though 



this is not the case in Europeans. Experiments showed that hungry 



bugs will feed in daylight ; the time of feeding varied from 4 to 12 



minutes. The longest time that a nymph was observed to live without 



food was 34 days ; in the case of adults this period was 19 days. 



Eggs laid on 1st February hatched on the 10th February and the bugs 



were full-grown on 18th March. At Buitenzorg the nymphs reached 



maturity after the fifth moult. The section deaUng with remedial 



measures reviews the various known methods for dealing with this pest.

A new Oestrid genus Kirkia'f, ha\dng recently been erected [see this 

 Review, Ser. B, ii, p. 91] for larvae the type of which was described 

 for the first time by Blanchard in 1893, the author deals with four sets 

 of larvae which evidently belong to a single species of this genus, for 

 which he proposes the name Kirkia surcovfi, sp. n. These were 

 obtained respectively from the frontal sinus of Bubalis sp. from Shari, 

 of B. inajor from Upper Senegal and the Ivory Coast, and of B. lichten- 

 steini from Portuguese East Africa. The larva originally described 

 differs from these and seems to constitute a distinct species, for which 

 the name K. blanchardi is proposed. 



Gedoelstia cristata, Rodh. & Beq., originally described as a parasite 

 of Bubalis lichtensteini from Katanga, is nov\- recorded from 

 Bubalis cohei and from Connochaetes albojubotus in East Africa. 

 G. hdssleri, sp. n., is described from larvae from antelopes in the 

 Niger delta, from Abyssinia, and from the nasal cavities of Damaliscus 

 lunatus in Uganda. 



A key to, and descriptions of, the species of Cobboldia are given, 

 viz. : — C. farumsjnnosa from the basin of the Zambesi, C. roverei 

 from the Belgian Congo, C. loxodontis from the Ivory Coast, Lake 

 Chad, Uganda and the Gold Coast, and C. elephant is from Asia. 



Oestromyia marmotae, sp. n., is described from a larva enclosed in 

 a cyst in the subdermal tissue of the paw of a marmot from Central Asia. 



Other new species described are : — Oestrus disjunctus, from the 

 nasal cavities of Hippotragus equinus in Katanga ; 0. compositus, 

 from unknown hosts in British East Africa, Mozambique, Abyssinia 

 and the Sudan, similar larvae, parasitic in Bubalis lichtensteini, having 

 been received from Katanga ; and Hypoderma gazellae, from the 

 dorsal muscle of the skin of Gazella granti from East Africa. 



[* Judging by the figure, it is more probably G. hemiptera, F. — Ed.] 

 [t Kh-kioostriis has since been proposed in place of this name which is 

 preoccupied, see this Bevicw, Ser. B, iv, p. 22. — Ed.]
