282 HIPPOBOSCIDAE (diptera pupipaea.) 



this genus by Austen in 1903. Neither of the species is recog- 

 nizable from the descriptions. I have consequently described 

 as new under the name of 0. makilingensis a species that I 

 have received from the Philippine Islands and the description 

 of this species is now in press in the Philippine Journal of 

 Science. This species is represented in the material at hand. 



1 may here call attention to a possible connection between 

 this genus and the genus Icosta Speiser. The latter was 

 based chiefly upon the peculiar character of the clypeal region, 

 which is identical with the condition found in 0. makilingensis. 

 The genus differs from Ornithophila in the supposed absence of 

 ocelli but 1 ain not able to avoid the suspicion tliat the t^vo may 

 be identical.

 fig. 2.) 



Specimens Examined. One male and one female from 

 Haematortyx sanguiniceps, Mt. Murud. The male is retained ; 

 the female is returned to the Sarawak Museum. 



Notes. This species was described from a single female 

 from the Philippine Islands and the description is in press at 

 the time of the present writing. This specimen is a female 

 in which the abdomen u as not fully expanded ; consequently 

 there are certain differences between it and the specimens 

 listed here which will be noted. The specimen having been 

 returned is not available for comparison but I feel no doubt as 

 to the identification. 



In the original description no mention was made of the pre- 

 sence of a small, chitinized plate on the dorsum of the abdomen 

 just caudad of the basal plate. Such a plate is present in the 

 female from Borneo and was probably merely retracted be- 

 neath the basal plate in the Philippine specimen. 



The length of tJie specimens at hand is 5 mm. for the female 

 and 4.5 for the male (on the slide) ; general color, after 

 mounting, a light brown. The male is here figured (Plate 11, 

 fig. 3). It differs fromjihe male but little, the abdomen being 

 less rotund and the external genitalia being represented by a 

 pair of small protuberances which are the vestiges of the 

 claspers. It is not possible on the basis of this specimen to 

 give any discussion of the internal genitalia. The wing (text
