Longicornia Malayana. 561 



gradually shading into black posteriorly; a grayish pu- 

 bescence behind the eyes; prothorax a little gibbous 

 anteriorly, its median lobe strongly marked ; scutellum 

 triangular; elytra sloped at the shoulders, parallel at the 

 sides, apices very slightly emarginate ; body beneath and 

 legs black, throat, coxas, and femora, at the base yellowish- 

 white ; posterior tarsi brownish, much longer than their 

 tibias ; antennae somewhat cylindrical, the joints slightly 

 dilated at their apices. 

 Length 4 lines. 



DEJANIKINiE. 



A very distinct genus, without any very obvious 

 affinities, is the sole exponent of this subfamily. M. 

 Lacordaire compares it in habit to CaUichroma. 



Genus. 

 Dejanira, Thoms. 



Dejanira. 



Dejanira) J. Thomson, Syst. Ceramb. p. 134; Lacordaire, 

 Gen. viii. 460. 



Caput subverticale, antice breve, postice constrictum. 



Oculi magni, prominentes, supra valde emarginati. 



Anteniice setaceae, corpore longiores ( c? ) , vel multo 



breviores ( ? ) ; scapo subconico, arcuato ; articulo 



tertio breviusculo, 4-10 gradatim longioribus { $) 



vel brevioribus ( ? ) . Prothorax subelongatus, late- 



raliter spinosus, disco insequalis. Elytra postice 



angustiora. Pedes modice elongati; femora sub- 



linearia; tarsi haud elongati; coxce anticse subtrans- 



versse. Prostermim postice verticale. 



A second species which I have added to this genus is so 



far aberrant as to cause M. Lacordaire to divide Dejanira 



into two sections, the first or typical form {D. quadri- 



punctata), the only one we have to deal with here, being 



distinguished by its elytra rounded at the apex and its 



sutural angle spined, the posterior femora with two teeth 



at the apex, and the mesostemum and presternum tuber- 



culate. These characters are absent in D. biajnculata. 



Dejanira quadripunctata . 



J. Thomson, Syst. Ceramb. p. 134. 



D. rufo-ochracea ; elytris apice rotundatis, sutura spino- 

 sa, et singulis maculis duabus parvis albis ornatis.
