more in series. The terminal joint is about equal to the ninth 

 in width, is evenly rounded, and slightly longer than broad. 



The right mandible is terminated by a single large pointed 

 tooth, with a slightly smaller tooth above and a little behind it. 

 The mandible-sac fills the space between these teeth and the broad 

 molar tooth. The left mandible is stout, and horizontally cleft at 

 the tip ; the lower external margin of the dorsal of the two teeth 

 so formed is finely and evenly serrate. There is a mandible-sac 

 and a large molar tooth. 



Dysantes elongatus, Redt. 



Hitherto recorded only from Java. A specimen was obtained 

 at SukU on the eastern side of the Dawna Hills (Tenasserim), 

 at an altitude of about 2000 feet. 



Platydema aurimaculata, n. sp. 

 (Plate xliif, fig. 3.) 



Kobo, 4000 ft., Abor Country, 30-xi-ir. A number of speci- 

 mens found in Poly poms. 



A convex elyptical, smoothly shining insect whose black 

 colour is varied with orange on the elytra. Length 3"8-4*5 mm. 



The head is rather sparsely punctured, transversely grooved 

 between the inner angles of the eyes, black behind this, black 

 fading to reddish-brown in front. The anterior margin of the 

 clypeus is straight or lightly concave, making a widely rounded 

 angle with the anterior margin of the canthus on each side. The 

 labrum is reddish-brown, with a number of short hairs in front. 

 In males a dorso-ventrally depressed horn of variable size pro- 

 jects from the middle line between the posterior margins of the 

 eyes. It is black at the base, but when well developed is red- 

 dish at the tip. 



The pronotum is black, occasionally tinged with reddish-brown ; 

 it is punctured like the head. 



The scutellum is small ; it is black or reddish. The elytra are 

 black with four irregular patches of orange, they are marked with 

 eight complete longitudinal rows of fine punctures (excluding the 

 marginal groove), and a short additional one near the scutellum. 



The under side of the head is black, that of the rest of the 

 body reddish-brown; the former is somewhat coarsely roughened, 

 the latter somewhat more finely punctured. The prosternum and 

 metasternum are not grooved or keeled in the middle line. The 

 mcsosternum is hidden. 



The antennae are 11- jointed. The first joint is longer and 

 stouter than the second ; the third is also longer than the second, 

 and is slightly thickened distally, but it is much smaller than the 

 first. The remaining joints are uniformly thicker than the third 

 but are of about the same length, except the last which is about 

 twice as long.
