form of the species. As the Bornean specimens, however, 

 are not constant in that respect, the length of the pronotal 

 angles in this species may be regarded as of a varietal 

 character. 



Tessaratoma absimilisy sp. n. 



Head, pronotum, scutellum, body beneath, and legs 

 greenish ochraceous ; corium brownish ochraceous ; mem- 

 brane cupreous; antenna ochraceous, second joint slightly 

 longer than either third or fourth joints, which are subequal 

 in length. Sternal keel reaching the anterior cox^e and 

 olivaceous in hue. Pronotum with the lateral margin oblique, 

 not dilated, and only very slightly convex. Body slender.

/- 



Pygoplatys tauriformis, sp. n. 



Pale olivaceous, obscurely punctate ; pronotal angles 

 strongly produced in long anteriorly curved spines, marked 

 with very coarse black punctures and with their apices sub- 

 acute and slightly recurved. Antennaa castaneous, the apical 

 joint (excluding apex) fuscous. Eyes, apices of the tibia?., 

 the tarsi, and lateral and apical margins of the abdomen 

 (narrowly) black, the last also spotted with ochraceous. 



Long. 21 millim. ; exp. pronot. angl. 20 millim. 



Hah. Tenasserim valley ; Myitta. 



Allied to P. trucidus, Walk., but with the pronotal angles 

 much more produced and curved outwardly. 



t- Pygoplatys lunatus^ sp. n.

 area profoundly and longitudinally sulcated. Corium very 

 finely and thickly punctate. Membrane cupreous. Abdo- 

 minal spiracles fuscous. Antennae pale fuscous, with the apical 

 joint ochraceous. 



Long. 20-23 millim. ; lat. pronot. angl. 16-17 millim.
