published a small paper on the Oriental Winthemia species but it cannot now be 

 used for identification as it was not based on any knowledge of the types and the 

 names are unreliable: a reassessment of all the Old World species of Winthemia 

 is much needed which would take account of the Oriental fauna, especially as it 

 relates to that of Australasia. It is now known that sexual dimorphism exists 

 in Winthemia in regard to colouring of the mesopleural hair, in several species 

 the hair being black in males but yellow in females; this makes reliable correlation 

 of the sexes difficult except where there are bred series, and means that some nominal 

 species based on types with hair of one colour may be synonyms of nominal species 

 based on types of the opposite sex with hair of another colour. An example is 

 W. albidopilosa Mesnil based on a female type with pale yellow mesopleural hair 

 which is here considered to be a synonym of W . neowinthemioides Townsend based 

 on a male type with black mesopleural hair. 



The Winthemiini are distinguishable from other tribes of Goniinae in the Oriental 

 Region by having the barette fully haired and by the possession (in most specimens 

 at any rate) of five setae on the humeral callus. In all Oriental forms the eyes are 

 densely haired, the hairing being exceptionally long in the genus Smidtiola. 



Key to Oriental Genera of WINTHEMIINI 



i Mid tibia with one submedian ad seta. Two stpl setae. $ without reclinate orbital 

 setae. Abdominal T5 in $ much wider at its base than its length in the mid line, 

 not at all subconical ........... 2 



- Mid tibia with several strong ad setae. Usually three stpl setae (two in the only 



known specimen of Smidtiola). $ with one pair of reclinate orbital setae (very fine 

 in Smidtiola). Abdominal T5 of rj subconical, its width at base not obviously 

 very much greater than its length ......... 3 



2 Parafacials bare ........ NEMORILLA Rondani 



- Parafacials finely haired on their whole extent . WINTHEMIA Robineau-Desvoidy 



3 Facial ridges strongly setulose for about two-thirds of their height. Head profile 



exceptionally strongly triangular, width of profrons conspicuously greater than 

 length of second antennal segment. Parafacials bare. Two stpl setae (perhaps not 

 constant, one specimen only known) ..... SMIDTIOLA Mesnil 



- Facial ridges bare (except for the usual very small setulae immediately above the 



vibrissae). Head profile not exceptionally strongly triangular, profrons not 

 noticeably wider than length of second antennal segment. Parafacials bare or 

 partially haired. Three stpl setae .... TIMAVIA Robineau-Desvoidy 



Tribe CARCELIINI 



This nearly cosmopolitan tribe is richly represented in the Oriental Region, 

 especially in the large number of species in the genus Carcelia s.l. The tribe as 

 here accepted is almost certainly, however, an unnatural grouping of forms some 

 of which should probably be placed in Eryciini and others in Goniini on a redefined 

 basis (indeed Herting and other workers have already gone some way in segregating 

 some of the Palaearctic constituents on these lines). But with the Oriental fauna 

 we are dealing at present with a quite inadequately studied miscellany of forms
