134 Mr. B. P. Uvarov's Notes on 



Since the name given to this insect by L. Bruner is not 

 pronounceable, I propose to alter it to v-plagiatus according 

 to the description of the species : " pronotiim marked on 

 the disk of the hind lobe by a v-shaped black patch the 

 apex of which points to the rear/' 



The species, which has been described from Manda 

 Island, British East Africa, seems to be very near to, if 

 not identical with, C. ferrifer Walk., differing only in the 

 peculiar mark on the pronotum which may be a result of 

 a reduction of the median fascia usual to C. ferrifer. Its 

 description and figure are, however, quite insufficient. 



The following key to the species of Caloptenopsis known 

 to me {i. e. except vitfatus, angusticeps, karschi and v- 

 plagiatus) may be useful : 



1 ^8) The lower inner spur of the hmd tibiae with the apex simply 

 recurved, without or with but short and not dense hairs. 



2. (3) Lateral keels of pronotum almost parallel, hardly divergent 



backwards; hind angle obtuse, rounded; metazona 

 scarcely longer than prozona. Fastigium between the 

 eyes distinctly broader than tlie frontal ridge between 

 antennae. Wings with the base rose. — India. 



C. glaucopsis Walk. 



3. (2) Lateral keels of pronotum strongly divergent backwards; 



hind angle straight, scarcely rounded; metazona much 

 longer than prozona. 



4. (7) Fastigium between the eyes not narrower than the frontal 



ridge at ocellum. Hind wings with the base rose. 



5. (6) Frontal ridge with the margins somewhat raised. Pro- 



notum more elongate and its lateral keels more strongly 

 divergent. Elytra extending well beyond hind knees. 

 Wings with the very base tinted with light rose. — N.E. 

 Africa C. cakaratus StS,l. 



6. (5) Frontal ridge with the margins very obtuse. Pronotum 



shorter, with the latei-al keels less strongly divergent. 

 Elytra scarcely extending beyond hind knees. Wings 

 almost wholly bright rose. — E. Africa. 



C. meruensis Sjost. 



7. (4) Vertex between the eyes narrower than the frontal ridge at 



ocellum. Hind wings with the base bluish. 



C. pallidicornis Stal. 



8. (1) The lower inner spur of the hind tibiae with the apex promi- 



nent beyond the base of the claw, in the shape of an 

 obtuse tubercle bearing dense and long hairs.
