300 CICINDELIDJE. 



Subfamily CICINDELIN^. 



This subfamily contains upwards of seven hundred species which 

 are distributed throughout the world, four genera being re- 

 presented in the Indian fauna ; one of these, Apieroessa, Hope, 

 contains one very remarkable species, of which no perfect example 

 exists, and which has not been found for more than a century. 



Key to the Genera. 



I. Mesosternum normal ; wings rarely 



reduced (some species of Frothy ma), 

 nearly always complete and well 

 developed. 



i. Underside entirely without pubes- 



cence* Prothyma, Hope* p. 300. 



ii. Underside with more or less pubes- 



cence. 



1. Underside practically without 



pubescence except for a distinct 

 fringe of white hairs on the 

 upper edge of the posterior coxal 

 cavities; elytra parallel-sided 

 with the apex, as a rule, con- 

 spicuously truncate obliquely. . Hkptodonta, Hope, p. 310. 



2. Underside with variable but dis- 



tinct pubescence, which is 

 sometimes very scanty, but 

 often thick or very thick and 



tomentose Cicindela, L. ; p. 314. 



II. Mesosternum with the episterna and 



epimera raised and projecting at 

 their exterior hind margin ; wings 



absent Apteroessa, Hope, p. 440. 



It is doubtful whether Prothyma and Heptodonta ought really 

 to be separated from Cicindela ; in any case there are species 

 which are now included under the latter genus which appear to 

 have as much right to be separated from it. 



Genus PROTHYMA. 



Frothyma, Hope, Col, Man. ii, 1838, p. 27. 

 Euryoda, Lacordaire, Mem. Liege, 1843, p. 107 (ex parte). 

 Jqnsenia, Chaudoir, Cat. Coll. 1865, p. 55 (ex parte). 

 Dromicidia, Chaudoir, Bull. Soc. Moscou, 1852, i, p. 21. 



Type, Cicindela quadripunctata, Fabr. 



The constitution of this genus is somewhat heterogeneous. 

 Dr. Horn includes in it upwards of fifty species from Africa, Mada- 

 gascar, India, the Malay region and China. The chief character- 

 istic is the total absence of pubescence on the underside * ; a few 



* Except in Prothyma bclloides, Horn, a species described since this table 

 was drawn up, and which ought perhaps to be referred to a separate genus.
