THOMSONIELLA. 277 



Hah. Sylhet; Decca-Day {fide !Sifjnoret). East Africa {fide 

 Melichar). 



Signoret (s?(/9ra) inclined to the opinion that the Ledra parva, 

 Walk, described from Houg Kong was a synonym of this species. 

 Walker's species belongs to the genus Ledrotupa^ Dist. (Ledrinse), 

 and is to be recognized by the presence of four dark granulose 

 spots on the scutellum. 



In his habitats Signoret writes: — " Decca-Day— Coll. Dist.", 

 and " Sylhet — Brit. Mus.," but at present the species cannot be 

 found in either of these collections. 



B. Vertex shorter than pronot%on.

" Yellowish-brown ; vertex shorter than posteriorly broad 

 between the eyes, in front leaf-like, compressed, strongly obtusely 

 angular, rounded off at tip, anterior margin acute, slightly raised, 

 a short deepened middle line in nape, two brownish spots near 

 posterior margin, and two brownish comma-shaped spots betv\een 

 the eyes ; face as long as broad, a strong black transverse fascia 

 below the margin of the vertex, and two series of narrow^ trans- 

 verse lines shortened below ; pronotum as long as vertex in middle, 

 behind finely transversely stippled, with six brown longitudinal 

 streaks truncated in front, each of the middle and lateral ones 

 approximate, lateral margins yellowish-white, near front margin 

 numerous brown spots and dots ; scutellum broadly triangular 

 vpith two short longitudinal streaks at base and between these a 

 line running to the apex, crossing the transverse line, and on both 

 sides of it a small oblique dash before the transverse line ; 

 tegmina brownish-yellow, costal margin yellowish-white, veins 

 strongly thickened and bordered with brownish; wings fuliginous ; 

 body beneath and legs yellowish-brown." {Melichar.) 



" Length $ 8 milHm'." 



Hah. Ceylon {fide Melichar). 



A single specimen agreeing generally with the above description 

 was sent to me from Ceylon (without precise locality) by my very 

 helpful friend Mr. Green. It is to be distinguished from the other 

 species here enumerated by the shorter vertex. 



Genus THOMSONIELLA.

* Signoret recognizing that his name Thomsonia was not sufficiently distinct 

 from Thompsoiiia, previously used in Crustacea, rightly substituted Thoinsonidla 

 for it.
