86 ON THE SYNONYMY OF THE PERLITES. 



Sp. 6. Isog. Dryrno. Caput testaceum, clypeo maculaque quadrata pos- 

 tica fuscis ; prothorax fuscus maculis duabus magnis lsete testaceis 

 signatus ; cetera fusca, femoribus basi pallidioribus. (Corp. long. A 

 unc. alar, dilat. 1.3 unc.) 



The head is testaceous, the clypeus dark brown, and on the crown of the 

 head adjoining the prothorax is a quadrate brown mark, from each of the 

 anterior angles of which a brown line passes to the root of the antenna : the 

 prothorax is dark brown, and adorned with two bright testaceous spots, which 

 are separated only by a very narrow, median, longitudinal, brown line, the 

 anterior portion of the prothorax is testaceous ; the other parts of the body 

 are dark brown ; the legs are of the same colour, with the basal portion of 

 femora paler : the wings are slightly suffused with brown, all the nervures 

 of the fore wings and the apical ones of the hind wings are dark brown. 



Inhabits Georgia. There are two specimens in the cabinet 

 of the British Museum. 



Sp. 7. Isog. Clio. Caput fuscum, lateribus circa oculos flavidis ; protho- 

 rax fuscus, linea mediana longitudinali flavida ; abdomen testaceum ; 

 antenna?, meso- et metathorax pedesque fusco. (Corp. long. .25 unc. 

 alar, dilat. 1.1 unc.) 



Head dark brown with lateral yellow marks surrounding the eyes, pro- 

 thorax dark brown, with a median longitudinal yellow line : abdomen rufo- 

 testaceous: antenna, meso- and metathorax, legs and caudal setae brown; the 

 fore wings and the costal portion of the hind wings are tinged with brown, 

 and have darker nervures. 



Inhabits Georgia. There are two specimens in the cabinet 

 of the British Museum. 



Genus V. — Chloroperla, Newman. 



In this genus the habit is still more slender, the wings still 

 more ample : the wing-nervures are much reduced in number 



*Species aberrantes. 



These have usually eleven nervures reaching the margin of 

 the forewing below the subcostal nervure. 



Sp. 1. Chlo. Spio. Testacea fere unicolor: ocelli duo fusco-nigri, oculi 

 magni, nigri ; caput prothorace latius : pedes incrassati : alae subob- 

 scurse iridescentes. (Corp. long. .35 unc. alar, dilat. 1.1 unc.) 



Colour a uniform and obscure but pale testaceous: the ocelli are two only 

 and of a dark brown colour; the eyes are black and very large, making the 

 head considerably broader than the prothorax : the yyrothorax is somewhat 

 quadrate, but broader than long, and broader anteriorly than posteriorly ; 

 its disk is wrinkled longitudinally : the wings are rather obscure, and obvi- 

 ously iridescent ; the legs are very stout, more so than is usual in this genus ; 

 the tibia are attenuated at both extremities, more particularly the apical ; 

 the tarsi are extremely small. 



Inhabits Sierra Leone. A single specimen is in the cabi- 

 net of the British Museum.
