 L. 4j-o mill. 



Oblong, rcddisli testaceous, with grey pubescence ; the 

 head, rostrum somewhat produced and truncate anteriorly ; 

 the thorax, anterior process wider in the female than in the 

 male, edges crenulate ; the elytra paler in colour than the 

 thorax, with somewhat variable dark markings. Thesutural 

 marking terminates before the apex at about two thirds of the 

 elytral length, and in the region of the scutellum it widens 

 out to half the width of the win^-case, on each side below 

 the humeral angle is a marginal detached infuscate spot, and 

 before the apex is a second and larger spot, which is usually 

 rather circular in outline, but sometimes it is confluent with 

 the sutural marking. Tiiere is a variety in which all the 

 dark markings extend and join. In the female the apices of 

 the elytra are rounded off; in the male they are truncate 

 near the suture and feebly acuminate near the middle. 

 The antennae and legs are wholly reddish testaceous. 



The general colour of this species resembles that in N. elon- 

 gatus, Lef., hinotatus, Gebl., and trinotatiis, Pic. ; the elytra 

 are less elongate and less parallel than those of trinotatus, the 

 species to which it is, on the whole, most similar.

Dusky brown ; antennrc, palpi, legs, and thoracic protu- 

 berance somewhat lighter in colour, thickly clothed with a 

 minute silken whitish ])ubescence. This species is somewhat 

 smaller than M. tenuipes^ Champ., with tlie thoracic protu- 

 berance less widened at the base, and the antenna3 are slightly 

 shorter taking them joint by joint ; the legs, and especially 

 the tarsi, are markedly shorter, but, except in colour, in other 

 respects they are closely similar. Both these si)ecies resemble 

 superticially Ilypaspistes armatus^ Waterh. (rigured in this 

 Magazine in 1S86, vol. xvii. p. 39), in the length of the 

 antenna? and tarsi, and I possess a third species from Ceylon 

 which also agrees with it. In M. minimus^ Mars., the legs 

 aiul tarsi are much shorter and the antcnnie also have the last 

 five joints shorter and relatively thicker.
