20 Mr. Gilbert J. Arrow's Contrihidion to ike 



Euniorphus helaeus, sp. n. 



Brunneo-niger, nitidns, singulo elytio bimaculato, maculis sa-t 

 parvis, flavis, rotundatis, anteriori ad huuieros haud attingenti; 

 prothorace lato, lateribiis valde bisinuatis, angulis posticis acutis; 

 elytris convexis, laevibus, haud costatis aut perspicue punctatis, 

 marginibus latissimis, apicibus acutis, haud productis; tibiis 4 

 posterioribus aicuatis : 



^, prothorace basi latissuiio, auguUs posticis acute productis et 

 curvatis; elytris conjunctim circularibus ; tibia antica ante apicem 

 fortiter si)inosa et emarginata, posterioribus 4 valde arcuatis et 

 intus dense hirsutis. 



Long. 16 mm.; lat. max. 11-5 mm. 



Hah. Sumatra : Me rang {Dohetiy). 



This very distinct species is related to E. turritus Gerst., 

 to which it is similar in size and coloration, but the ground- 

 colour is rather darker and scarcely at all metallic. The 

 elytral margins are even wider than in that species and a 

 little more curved upwards, the discoidal part is regularly 

 convex, without median elevation or lateral costae, and the 

 yellow spots are less raised. In the male the tibiae are 

 stouter and their inner edge (in the front tibiae as well 

 as the rest) is closely fringed with rather long hairs. The 

 spine upon the front tibia is stout, clothed with hair, 

 placed nearer the extremity than in E. iurritus, and followed 

 by a deep abrupt excision. 



Two males and three females were taken by Doherty. 



Eumorphus fraternus, sp. n. 



E. helaeo valde affinis sed paulo magis attenuatus, elytrorum 

 marginibus postice productis, apicibus acuminatis, contiguis : 



(^, elytris conjunctim ovalibus, lateraKter paulo minus latis, 

 tibiis omnibus ciliatis, antica torta atque fortiter spinosa. 



Long. 13-14-5 mm. ; lat. max. 7-9 mm. 



Hah. Malay Peninsula : Perak {Doherty). 



Six specimens were contained, hke those of the three 

 preceding species, in the Fry Collection. 



E. fraternus closely resembles E. helaeus, but the elytral 

 margin is a httle narrower at the side and a Httle wider 

 at the apex, with the extreme angles acutely produced 

 and convergent. The front tibia of the male is a httle 

 less pubescent at the inner edge and the apical excision
