CLA.MBID.E. — LEPTIJf'IDJE. 



85 



and Choleva are each represented in India by one or two species, 

 and possibly examples of the Liodexoe, etc., may be discovered, 

 but no one as yet appears to have worked at the group, so far as 

 the Indian fauna is concerned. 



The SphvEritldyE and Clambidte have been classed with the 

 vSiLPHiDiE, but through the wing venation the former family 

 approaches rather to the Nitldulid.e, and the ciliation of the 

 margin of the wings appears to separate the latter. 



The subfamilies may be distinguished as follows : — ■ 



I. Anterior coxal cavities closed behind. 



1. Episterna of mesosternum rather large and sub- 



quadrate ; trochantins of anterior coxa3 small, 



nearly or entirely covered Cholevinje. 



2. Episterna of mesosternum small and linear ; 



trochantins of anterior coxae larger and free . . Liobin.e. 



II. Anterior coxal cavities open behind Silphiisle 



Family 16. CLAMBIDJE. 



Minute, very convex, more or less hemispherical insects; head 

 very large, as large as, or larger than, the pronotum when exserted ; 

 antenna} 10- or S-jointed with a 2-jointed club ; max dice with two 

 narrow and rather long lobes; elytra without epipleurce ; wings in 

 part -finely ciliate on their edge; posterior coxce laminate; tarsi 

 4 : jointed ; abdomen with jive, six, or seven free segments. 



The species of this family are closely related to the Silphid.e 

 on the one hand, especially to Agathidium, and they have the 

 power of rolling themselves up like the members of the latter 

 genus ; they also have affinities towards the Trichopterygid.e 

 and SphyEriidyE. The species are found under decaying bark, in 

 decaying vegetable refuse, and in hotbeds, etc. 



The larva of Calypiomerus has been described by Perris (Ann. 

 Soc. Erik France, 1852, pp. 574-577, pi. xiv, figs. 1-7); it is 

 2 mm. in length, elongate, and differs from the larvae of some of 

 its allies in being considerably narrowed in front and behind, with 

 the greatest breadth at the metathoracic segment. 



The species are almost entirely confined to Europe and North 

 America; one species of Clambus has been described from Ceylon, 

 and one from the Canary Islands. 



[Family 17. LEPTINID.F ] 



Mentum transverse with, the posterior angles more or less prolonged; 

 labrum very short; antennce long, filiform ; anterior coxce small; 

 metasternum very short; eyes entirely wanting or almost obsolete; 

 tarsi five-jointed ; size small.
