LEMA. 29 



long, nearly black, the third joint one half as long as the fourth, 

 all the joints thickened but elongate. Thorax slightly longer than 

 broad, concave at the middle of the sides if looked at from above ; 

 lateral cavities deep with the usual ridge above, basal sulcus only 

 indicated at the sides ; the disc impunctate with a small fovea near 

 the base, anterior angles obsolete. Elytra dark brown, closely 

 impressed with large and deep foveolate punctures, the interstices 

 transversely convex, the punctures absent on the apical third 

 portion where the interstices are strongly longitudinally costate. 

 Body beneath and the legs nearly black. 



Length 10 mm. 



Hah. Burma : Pegu. Type in Brit. Mus. 



A large and very distinct species, with more strongly punctured 

 elytra than any of its congeners and the sculpturing altogether 

 different ; also the shape of the thorax. 



49. Lema subtuberculata, sp. n. 



Entirely fulvous. 



Head constricted behind the eyes, neck long ; intraocular space 

 strongly bituberculate ; antennae fulvous, the third joint much 

 shorter than the fourth, the following joints elongate and slender. 

 Thorax with the anterior portion rather strongly obliquely widened, 

 the lateral constrictions form a deep cavity with the usual ridge 

 above, the surface with a very small tubercle at each side close to 

 the anterior margin followed by a short elongate fovea, the rest of 

 the surface impunctate ; the basal sulcus deep and placed at some 

 distance from the base. Scutellum rather small, subquadrate. 

 Elytra with a shallow basal depression, the punctures very fine 

 except on the basal portion, the first sutural row simple, the inter- 

 stices at the sides feebly and broadly raised. Below and the legs 

 fulvous, not pubescent. 



Length 9 mm. 



Hob. Assam : Patkai Mts. Type in Brit. Mus. 



Whether the peculiar structure of the thorax is aberrational or 

 not it is impossible to say, as only a single specimen is before me ; 

 this coupled with the elongate neck should prevent its being 

 confounded with any other species. 



50. Lema palpalis, Lacord. Mon. Phytoph. i, 1845, p. 315. 



Entirely pale flavous. 



Head raised between the eyes, the elevation divided by a groove ; 

 last joint of palpi strongly swollen; antennae filiform, flavous, 

 third joint half length of fourth, fourth and the following joints 

 equal. Thorax subquadrate, impunctate ; lateral constriction very 

 deep, separated from the basal sulcus by a distinct perpendicular 

 ridge, anterior portion rather strongly widened, the angles some- 

 what prominent but not tuberculate. Elytra with feeble basal 

 depression, the punctures strong within the latter, rest of surface
