280 HIPPOBOSCIDAE (DIPTERA PUPIPABA.) 



dry, pinned specimens being unsuitable because of the shrinking 

 of the soft bodies. I need not again enlarge upon the methods 

 which I consider should be followed, other than to say that 

 for my own work I employ specimens which have been mounted 

 on shdes after suitable preparation. 



Of the two alternatives indicated above I have chosen the 

 second, but in case a species may with reasonable certainty 

 be referred to a named form I have done so. Where any 

 considerable doubt exists I have not hesitated to describe species 

 as new. One unfortunate feature of most of the systematic 

 work on this group is the almost complete lack of figures. 

 Because of this I am presenting figures wherever anything at 

 all is to be gained by doing so. It is my hope that the species 

 here dealt with may be readily recognizable from the descrip- 

 tions and figures given. 



Gents OENITHOICA Rondani. 



Hippoboscidae with functional and non-caducous wings in 

 which there are seven veins behind the costa and three cross- 

 veins, the third vein (R4-f-5) approximate to (usually said to be 

 confluent with) the second vein (R2-J-3) for a considerable por- 

 tion of its length : ocelli present ; claws two-toothed. 



Several species, most of which are from the Eastern Hemi- 

 sphere, have been refen'ed to this genus, but the status of most 

 of them is very dubious. I am. however, referring the single 

 specimen in the collection at hand to a mimed species for, as 

 far as may be judged from the hterature, it in all probability 

 belongs to this. 



Ornithocira beccariina Rondani. (Plate 11, fig. 1; text, 

 fig. 1.) 



Specimens Examined. A single female from Cissa jeffreyi, 

 Mt. Murud. This specimen is returned to the Sarawak 

 Museum. 



Notes. The more distinctive features of this species are as 

 follows. Lensth (on slide i 3 mm., length of head and thorax 

 1.75 mm. General color dark brown. Abdomen with but 

 three transverse plates on the dorsum in addition to the basal 

 .plate and the paired apical plates, differing in this respect from 

 0. proyyiiscna Ferris and Cole and 0. turdi Latr. which have 

 four plates. Ventral side of the abdomen without a cluster of 

 chitinous, seta-bearing tubercles at the margin near the base
