64 MYCETOPHILID^E. 



There can be no reasonable doubt of the correct identification of 

 this species. Walker described it from the " East Indies." His 

 " testaceous stripe on each side " is a thin yellowish line from 

 above the humerus, running below the lower edge of the dorsunv 

 nearly to the wing-base. 



17. Platyura octosegmentata, sp. nov. 



c? . Head yellowish, vertex rather brownish ; ocelli distinct, on a 

 dark, slightly elevated tubercle. Antennae reddish yellow, also 

 back of head. Thorax brownish yellow ; dorsum with short 

 scattered black bristles and the lateral margins with stronger 

 ones, especially behind the wings ; a few below the shoulders, and 

 a few on the posterior corners, each of which latter bears a large 

 round black spot. Scutellum yellow, with a row of numerous 

 bristles extending over nearly the whole length of the margin. 

 Abdomen distinctly 8-segmented; first two segments wholly 

 yellowish ; remainder more or less marked with brown towards 

 sides and hind margins ; belly yellowish ; abdomen above and 

 below with short black pubescence. Grenitalia yellowish, incon- 

 spicuous, apparently normal, the second joint of the claspers long 

 and slender. Legs : coxae yellowish : tibiae dirty yellowish white, 

 tarsi blackish. Wings pale yellowish grey ; halteres yellow. 



Length 3 millim. 



Described from a single male taken by Mr. A. D. Imms,. 

 9. ix. 09, at Allahabad, United Provinces, and kindly presented 

 by him to the Indian Museum. 



The abdomen has normally seven segments in this genus ; I do 

 not know of any exceptions, but refrain nevertheless from estab- 

 lishing a new genus at present for the reception of this species. 



18. Platyura ruficornis, sp. nov. 



. Head rather deep brownish yellow ; antennae concolorous, 

 considerably pubescent ; vertex blackish, palpi a little darker. 

 Thorax, scutellum and metanotum concolorous. Dorsum of thorax 

 covered with short black pubescence, which becomes strongly 

 bristly on the margins, above the wings. Scutellum with a row 

 of bristly hairs on posterior margin, with some smaller ones below 

 these, dorsum bare. Abdomen apparently variable ; in one 

 example wholly light brown, in two others more yellowish brown,/ 

 with the posterior parts of the segments more or less black. Legs 

 dirty yellowish; coxae brighter and rather darker, tarsi black. 

 Wings distinctly yellowish ; halteres brownish yellow. 



Length 3-4 millim. 



Described from two specimens from Sylhet, Assam/2, ii. 05 and 

 30. ii. 04, and one from Naini Tal, United Provinces, 10. vi. 09.. 

 All in the Indian Museum.
