METISOLABIS. — CIENISOLABIS. 109 



Without seeing the insect it is easy to place it in its true position. 

 It differs from B. caudelU in the uniform reddish legs, in the 

 more strongly convergent keels of the mesonotura, which is thus 

 more strongly narrowed posteriorly, and in the absence of the 

 lateral fold on the third segment of the abdomen.

Colour, texture, form, and pubescence typical. Antennae with 

 15 segments, black with a pale ring before the apex ; the segments 

 rather long ; the third segment about twice as long as broad ; the 

 fourth more than half as long as the third ; the fifth quite as 

 long as the third, if not a trifle longer; almost cylindrical. 

 Mesonotum with the keels gently bowed at the shoulder and 

 gently converging posteriorly. Femora black, yellowish towards 

 the apex ; tibiae brownish yellow, tarsi pale. Abdomen typical, 

 third and fourth segments with lateral tubercles. Forceps stout 

 at base, rapidly tapering, gently arched, not contiguous in the S , 

 contiguous in the 2 .

Type in the author's collection. 



Apparently common in Further India. This species was con- 

 fused by de Bormans with B. punctata, Dubr., from Java, but 

 that species has no keels on the pronotum and falls into Leptiso- 

 labis, Verh. 



Genus CTENISOLABIS, Verh.

Type, Ct. togoensis, Verh. 



This genus agrees with Metisolabis in the form of the eyes and 

 keeled mesonotum, but differs in the short, almost globular, 

 antennal segments. With Nannisolahis it agrees in the form of 

 the antennae, but has a keeled mesonotum and lateral eyes. 



Range. Three species are at present placed in this genus ; one, 

 the type, Ct. togoensis, Verh., is African ; the other, Ct. nigra, Scudd., 

 occurs in South America ; the third in Ceylon.
