TACHINIDAE OF ORIENTAL REGION 105 



on the other hand, in having parafacial bristles, haired hind coxa, and three sterno- 

 pleural setae, but differs very obviously in the setulose 7? x and ^ 4+5 , in possessing 

 palpi and hairing on the propleuron, in having two (instead of three) post ia setae, 

 and in possessing discal setae on the intermediate abdominal tergites. A note- 

 worthy character by which Tothillia differs from both Schineria and Cuphocera, 

 and almost all other Tachinini, is the presence of hairing on the lower surface of 

 the second costal sector. 



At present Tothillia is monotypic for T. asiatica (Tothill) and is known only 

 from northern India. 



Key to Oriental Genera of TACHININI 



[Note. The genus Schineria Rondani is included in the following key because it occurs in 

 central and northern China. A specimen of S. majae Zimin from Nanking, just outside the 

 Oriental Region, is in the BMNH collection. Two specimens oiSchineria from Tonkin mentioned 

 by Mesnil (1970a : 975) have not been seen and have been left out of consideration in the 

 present work.] 



1 Wing with first and third veins (i?j and R ) + 5 ) setulose along almost the whole of their 



length on both upper and lower surfaces (Text-fig. 96). Parafacials with some 



very strong setae in addition to the hairing . . . TOTHILLIA gen. n. 



- Wing with first and third veins (K t and /? 4+5 ) totally bare except for the usual fine 



hairs or setulae on the basal node of i? 4+ 5 . Parafacials without strong setae as well 



as hairing (except in Cuphocera) ......... 2 



2 Parafacial armed with two or three strong setae at its lower end. Propleuron bare. 



Palpi absent. 1 + 3 ia setae CUPHOCERA Macquart 



- Parafacial uniformly haired and without any strong setae (at most a few hairs slightly 



stronger than the others). Propleuron haired. Palpi present (sometimes small). 



1 + 2 ia setae (very rarely only 1 + 1). . . . . . . . 3 



3 Hind coxa bare on the posterodorsal surface. Cell R b short-petiolate 



SCHINERIA Rondani 



- Hind coxa haired on the posterodorsal surface. Cell R b open to the wing margin 



(sometimes very narrowly) .......... 4 



4 Abdominal Ti + 2 without median marginal setae. Palpi slightly ($) to very 



strongly ($) clubbed. Bend of vein M usually with a definite M 2 appendix in 

 addition to the dark fold. Second costal sector often haired ventrally (or partially 

 so). Eyes bare or haired ....... MIKIA Kowarz 



- Abdominal Ti -f 2 with at least one pair of erect median marginal setae, usually with 



a well developed transverse row of such setae. Palpi parallel-sided, usually strongly 

 filiform. Bend of vein M without a definite appendix, with only a trace of a 

 darkened fold. Second costal sector bare ventrally. Eyes always bare . . 5 



5 Mesonotum, scutellum and abdomen metallic blue-violet (appearance similar to 



J anthinomyia) CHRYSOMIKIA Mesnil 



- Non-metallic forms without such coloration . . • . . . . . 6 



6 One post ia seta. Second supra-alar seta absent (supra-alar area of scutum therefore 



with only two setae, the pre-alar and the first supra-alar). One prst dc seta. 

 Antennae exceptionally elongate, virtually reaching to epistomal margin and 

 second segment as long as the maximum eye- width. Facial ridges bare and 

 shining. Wings distinctly bicolorous, orange-yellow basally (especially anteriorly) 

 and greyish brown apically. Humeral callus with three setae. Mesonotum and 

 scutellum with vestiture of short bright orange lanceolate hairing ; abdomen shining 

 black with two transverse basal bands of bright orange hair
