110 LABIID^. 



61. Ctenisolabis fletcheri, sp. u. (Fig. 79.) 



Small, black, puuctulate. Aiitennse with 13 segments, all short 

 after the first ; third about as long as broad, fourth and fifth 

 globular, the others slightly lengthening, but the apical seg- 

 ment is only a little longer than broad ; from the third towards 

 the apex all the segments become gradually thicker. Head 

 typical : the eyes large and prominent, but not reaching so near to 

 the posterior margin of the head as in some species. Pronotum 

 wider than the head and still wider posteriorly, distinctly longer 

 than broad, with a distinct neck in front, which carries the head. 

 Mesonotum ample, the keels distinct but blunt, bowed outwards 

 at first and arched gradually inwards, dying out just before 

 reaching the posterior margin. Metanotum ver}^ ample and very 

 strongly sinuate. Legs typical. Femora black, tipped with 

 reddish, tibiae and tarsi reddisli. Abdomen typical; tubercles 

 on third and fourth segments not very distinct, smooth spot on 

 fifth segment distinct. Last dorsal segment gently sinuate. 

 Penultimate ventral segment very ample, rounded. Forceps con- 

 tiguous, simple, overlapping. 



Length of body 10 mm.

The keels of the mesonotum are very blunt and thus represent 

 a passage to Leptisolahis. 



It may be distinguished by its generic characters from the only 

 species with which it is Hkely to be confused. 



Family IV. LABIID.E. 



This family contains a number of heterogeneous forms, and is 

 in great need of revision.^ A considerable number of species are 

 known, but relatively few are recorded from India, representing 

 five genera. 



The discrimination between the smaller forms of Spongiplwra 

 and larger ferms of Labia is rather subtle, and the generic 

 characters must be examined with care. 



Only one subfamily, the Labiince, is known to be represented 

 in India ; but it is quite probable that sonie member of the 

 Nesoyastrince may be discovered, probably towards the eastern 

 bounds of the area. 



^ For this reason, the generic definitions in tliis family must be regarded as 

 purely provisional.
