PLAGIOLEPIS. 323 



from the side the thorax is more level above, the meso-metanotal 

 emargination not being so broad or deep. 



Length, 2-5-4 mm. 



Hob. Spread throughout the whole of Burma and Tenasserim, 

 and extending into Siam ( Watson, Allan, Thompson).

. Brownish yellow, with a brown shade on the head and 

 posterior portion of the abdomen; moderately smooth and shining, 

 with minute, somewhat sparse punctures, most distinct on the head 

 and abdomen ; pilosity short, sparse and scattered ; pubescence fine, 

 thin, white in colour, moderately dense on the head, antennae, 

 legs and abdomen. Head without the mandibles nearly square, 

 very convex in front, transverse posteriorly ; mandibles triangular, 

 the masticatory margin dentate, straight ; clypeus comparatively 

 large, strongly convex, and not carinate ; antenn slender, the 

 scape barely extending beyond the top of the head. Thorax 

 narrower than the head ; the pronotum convex and rounded in 

 front, but somewhat depressed as compared with P. rothneyi, 

 P. wroughtoni and other species ; the meso-metanotal emargination 

 distinct, the metanotum about as broad as the prouotum, its basal 

 portion very short, much shorter than its oblique apical portion. 

 Node of the pedicel low, somewhat thick at base, rounded above ; 

 abdomen comparatively broad, oval, gibbous anteriorly. 



" $ . Very narrow, abdomen elongate. Eesembles the > but 

 the pubescence is thicker and more abundant. The head and 

 thorax are of a brownish or reddish yellow. Abdomen entirely 

 brownish or of a yellowish brown. Thorax strongly depressed 

 above. Node of the pedicel very low, strongly inclined to the 

 front; wings wanting." (Forel.) 



Length, g 1-1-5 ; $ 2-5-3 mm. 



Hab. Western India ( Wroughton). Found also in Madagascar.

. Yellow, the head shading to light or sometimes to dark 

 brown ; head, thorax and abdomen smooth and shining ; pilosity 

 very sparse, almost entirely absent. Head as in P. evigua, but much 

 broader posteriorly and proportionately more narrowed anteriorly. 

 Thorax longer, the metanotum transversely concave down the 

 middle. For the rest like P. exiyua, but larger and proportionately 

 more slenderly built. 



Length-, $ barely 2 mm. 



Hab. Sikhim (Moller), Bengal (Itothney). 



I am not very certain whether one rather damaged specimen 

 received from Mr. Moller is this species. Dr. Forel's short 

 description agrees fairly well with the Sikhim specimen, only the 

 latter seems smaller, scarcely 2 mm. long.
