Seven 9; c? unknown. Tarsi as in ferruginea. Differs from C. undata, Pictet, 

 in the setie no*, being annulated, in the costal margin being umber brown, not 

 fuscous, and in there being no fuscous cloud on the disk and posterior margin 

 of the front wing. 



Cloe tjnicolcr? Hagen. ^ Obscure piceous. Eyes shrivelled, but appa- 

 rently double; seta of anteurue fuscous. Abdominal seta pale, cloudy at tip. 

 Legs all pale yellowish ; tips of tarsi cloudy. Wings hyaline, veiu3 moderate, 

 cross-veins Sne, the former sometimes sligbtly dusky, the latter hyaline ; iso- 

 lated veinlets in pairs. In the hind wings the space between the two veins is 

 subopaque, and thf:re are no cross-veins. 



On the vertex 9 there is a longitudinal dilated stria; the abdomen is bright 

 ferruginous, with the incisures in the living insect pale, and a pale, lateral spot 

 on each segment. 



Length tf 2 J mill; 9 5 mill. Alar exp. $ 9 mill; 9 1213 mill. Seta $ 

 5 mill; 9 6 mill- One (J 1 , three 9- The diagnosis oiunkolor, Hagen, is very 

 brief. 



Cloe vicina? Hagen. $ Piceous. Eyes in the living insec 1 , as in C. ferrugi- 

 nea, but the lower eye is not attached laterally to the upper eye, a3 in all other 

 species with double eyes known to me, but at its posterior corner; seta of 

 antenna; fuscous, pale at tip. Joints of abdomen whitish hyaline, with a 

 lateral dot on each, except the four last, which -are piceous; venter pale hya- 

 line, the four last joints opaque whitish ; seta? whitish, the incisures often 

 fuscous towards the base. Legs pale, except the anterior femur, which is some- 

 times pale ferruginous ; tips of tarsi cloudy. Wings hyaline iridescent ; veina 

 moderate, cross-veins very fine, all hyaline; isolated veinlets in pairs. In the 

 hind wings the space between the two veins is subopaque, and there are no 

 cross-veins. 



The 9 differs in the head, thorax, sternum and abdomen being ferrugino- 

 piceous, sometimes ferruginous ; the venter is reddish white. The anterior fe- 

 mur is always immaculate.

 mill. Seta ^ H 10 mill. ; $> 5 9 mill. Seven tf, sixteen 9 Very near po- 

 sticata, Say, butdiffers in size, and in the wings not being white. 



What, I have no doubt, is the subimago of the above, (see below apud. C. 

 dubia,) differs in the colors being obscurer, and the (J 1 abdomen dull-whitish- 

 hyaline at base, sometimes obscure greenish. Tarsi sometimes dusky. Wings 

 fumose, the veins rather coarse and dusky, the cross-veins the color of the wing. 

 The cilia are close-set. and about one-half millimetre long. At first sight very 

 like B. debihs, subimago. 



Length $ 3 3J mill.; 9 3,} mill. Alar exp. tf 11 mill.; 9 8^14 mill. 

 Seta tf 5 mill. ; 9 4 mill. The $ 9 anterior tarsi are short and subequal. Two 

 tf, three 9. 



\\Cloc Subgenus C. Two wings; cross veins sparse, about 14 18 in 

 number. 



Cloe dubia, n. sp.? Differs from the preceding in size, and in the total ab- 

 sence of hind wings. The lateral abdominal dots <$ have generally a hyaline 

 centre, and the $ eyes are normal. 



The 9 differs from the 9 f vidua in the head, thorax, sternum and abdo- 

 men being pale ferruginous, the head and abdomen occasionally obfuscated. 

 The venter is pale yellowish or greenish ; and the anterior femora are always 

 more or less ferruginous.

The subimago, from which I have bred numerous imagos, differs from the 

 imago precisely as that of the preceding. The dimensions are similar to those 

 of the imago. Nine $, ten $ As Dr. Hagen has not stated whether his vi-
