the Species of Calascopus. 457 



be new, although I cannot finally determine this point until 1 am 

 certain of the characters of the species described by Schmidt 

 Gobel in his Birman Fauna. 



1. Catascopus Schaum'ii, W. W. S. (PI. XVI I. fig. 3.) 



Above, shining, brilliant, metallic blue-green, the elytra crossed 

 a little below the centre with a broad, ill-defined, dark-purple 

 band ; underside of body dark purplish-green. 



Head broad, slightly contracted towards the thorax, with two 

 deep, longitudinal foveas between the eyes ; the upper surface 

 rounded and minutely pimctured. Antennae rather short, robust, 

 dark bronzy-purple, as well as the parts of the mouth. 



Thorax rather broader than long, wider than the head, much 

 contracted posteriorly, the lateral margins narrowly margined and 

 rounded, the anterior margin very slightly emarginate, the pos- 

 terior margin sh'ghtly sinuate, and the hinder angles sharply 

 pointed, with the upper surface very finely striate transversely, 

 and having a deep transverse depression a little behind the anterior 

 margin, and a central longitudinal furrow, commencing at the 

 transverse depression and reaching nearly to the hinder margin. 



Elytra broader than the thorax, half as long again as broad ; 

 the shoulders prominent and slightly rounded, the lateral margins 

 nearly straight and parallel, rounded posteriorly, with a deep 

 emargination at the apex of each elytron, the commencement of 

 the emargination having a sharp, broad tooth, and there being two 

 small teeth at the termination; the surface of each elytron with 

 eight deep striae more or less punctate, and the interstices nearly 

 smooth. 



Legs robust and rather long. Tarsi ferruginous-brown. 



Length -j8jy inch. 



Hab. Sarawack. Wallace. 



This is the largest species of Catascopus with which I am ac- 

 quainted, and at the same time the most brilliant and rich in its 

 colours. The size, and the broad purple band across the elytra, 

 easily distinguish it as a species. In position it seems to ap- 

 proach to C. Withillii of Hope, which is found on the continent of 

 India. I have named it after Dr. Schaum, so well known for his 

 extensive and accurate knowledge of Entomology, and especially 

 for his acquaintance with the family of insects to which Catascopus 

 belongs. I am much indebted to him for aiding me in determining 

 the species described in this paper.
