S. Catascopus rugicollis, W. W. S. (PI. XVIII. fig. 6.) 



Colour dark bronzy-green, with the thorax slightly suffused 

 with copper colour, and having the parts of the mouth, antennae, 

 legs and underside of the body shining purplish-black. 



The head is elongate, somewhat constricted behind, with the 

 upper surface shining, minutely rugoso-punctate, and with two 

 rougli, shallow depressions in front, nearly in a line with the base 

 of the antennae, from which proceed narrow, line-like depressions, 

 running close to and nearly encircling the eyes. Antennae stout, 

 and rather short. Eyes prominent. 



The thorax is transverse quadrato-cordiform, with the anterior 

 and posterior margins straight; the angles prominent, the sides nar- 

 rowly margined, and curving inwards towards the base. The upper 

 surface is deeply and transversely striate, with a well-marked 

 central longitudinal depression running from the base to near the 

 anterior margin, where it branches right and left, and passes on 

 to the anterior margin, enclosing a smooth, broadly triangular area. 



The elytra are considerably wider than the thorax, once and a 

 half as long as broad, with the sides nearly parallel and slightly 

 emarginate a little behind the shoulders, which are somewhat pro- 

 minent and rounded. Each elytron is produced into an acute, 

 somewhat diverging spine, the apex being rounded and slightly 

 emarginate before the spine is reached. The upper surface of 

 the elytra is smooth and shining ; each elytron with nine, nearly 

 equally spaced, longitudinal, slightly punctate, shallow striae. 



The underside of the body is smooth and shining. 



Legs moderate in length. 



Length -j-4j inch. 



From Macassar. In Mr. Wallace's collection. 



This species is near C. aculeatus, Chaud., but may at once be 

 distinguished by the shape and sculpture of the thorax. 



4. Catascopus punctipennis, W. W. S. (PI. XVIII. fig. 4.) 



The colour is rich, shining, brassy-green, with the parts of the 

 mouth, antennae, underside of the body and tarsi purplish-black. 



The head is elongate, constricted behind the eyes, with the 

 upper surface longitudinally, but irregularly, striate, and much 

 more deeply so in front, where it is very rugose. The eyes are 

 rather small and prominent. 



The thorax is rather longer than broad, quadrato-cordate, about 

 as broad as the head, with the anterior angles rounded, the hinder 

 angles prominent, the sides narrowly margined, the anterior margin 

 straight, and the posterior slightly rounded. The upper surface
