DESCRIPTION OF TYPHLOCYBA TILIJS, GEOFFR. 

 BY JAMES EDWARDS. 



Having made the acquaintance of tliis insect, and ascertained the 

 equity of its claim to rank as a distinct species, which has been much 

 questioned, it has occurred to me that a detailed description and some 

 comparative remarks might be acceptable. 



Head bright yellow. Prouotum in front bright yellow, behind whitish, anterior 



margin with three large, nearly round, whitish spots. Scutellum deeply transversely 



impressed on apical third, with a reddish triangular spot at each basal angle. 



Elytra milk-white ; clavus, anterior margin of corium broadly, and 1st, 2nd, and 



4th cells of membrane, fuscous. Corium more or less sprinkled with reddish atoms 



placed more closely along the course of the 1st nerve, and forming a more or less 



distinct patch between the apex of the 1st and 2nd nerves ; membrane, 3rd cell, 



milk-white, nerves yellow. Legs pale yellowish ; $ , 1st and 2nd pairs, tarsal claws 



fuscous ; 3rd pair, tarsi entirely, and extreme apex of tibise, black ; $ , as in T. blan- 



dula. Abdomen yellow, base sometimes blackish. 



Length, Ij lin. ; expanse, 3^ lin. 



Exceedingly like pale examples of T. hlandula, but differs in being 

 slightly larger, and in the markings on the pronotum, which characters 



will always serve to se- 

 parate the females of the 

 two species. The differ- 

 ence in the form of the 

 outer genital processes of 

 the ^ of the two species, 

 will be seen from the 

 ^- figures : 



(1) tilice, (2) hlandula. 

 Beaten from firs at Ringland, not uncommonly in March, but very 

 local.

NOTES ON AFRICAN IIE2IIPTERA-HETER0PTERA. 

 BY W. L. DISTANT. 



In a small collection of Hemiptera made by Mr. Simons at Liviu^- 

 stonia, Lake Nyassa, the same general absence of new species was 

 observed as is recorded by Mr. Hewitson (p. 51 ante) of the Rhopalo- 

 cera in the same collection. There seems no doubt that the East 

 African fauna undergoes little change tili the longitude of the Great
