New Malayan Rhyncliota. 389 



and widely emarginate anteriorly ; mesosternum broadly centrally 

 elevated and posteriorly broadly sinuate ; femora spined at inner 

 apical margins. 



Long. 9 • 44 mm. Exp. pronot. angl. 29 mm. 



Eab. Malacca (Brit. Mus.). 



Allied to A. atlas, Stal, but apart from the different 

 colour of body and legs it differs by the larger size, 

 straighter and more angular apex of scutellura ; fourth 

 joint of antennae distinctly longer than second — about as 

 long as second in A. atlas, mesosternal process anteriorly 

 more widely emarginate, etc. 



A second specimen is contained in my own collection 

 from the Malay Peninsula, and in this the veins to the 

 corium and the claval veins are distinctly paler in hue. 



Sanganus, gen. nov. 



Broadly subovate, abdomen apically broadly truncate ; head 

 small, about as long as broad including eyes, lateral lobes much 

 longer than central lobe, obliquely narrowing to apex ; ocelli much 

 nearer eyes than to each other ; rostrum about reaching middle of 

 mesosternum, basal joint very slightly passing base of head, apical 

 joint small and incrassate ; antennae four-jointed, fourth joint about 

 as long as second ; pronotum about twice as broad as long, the 

 lateral angles forwardly and slightly outwardly produced, posterior 

 margin subtruncate ; scutellum much broader than long, the apex 

 prominently narrowed and produced; abdomen broad, posteriorly 

 broadly truncate, connexivura exposed for about one-third of base 

 of lateral margin of hemelytra ; prosternum centrally longitudinally 

 sulcate ; mesosternum with a central flat process which for half its 

 length is centrally sulcate, metasternum with a central angulate 

 process behind the intermediate coxae, not prominently raised ; legs 

 of moderate length, femora and tibiae almost equally long, the tibiae 

 straight ; femora apically spined. 



Type, S.jenseni, Dist. 



This genus is allied to Oxylohus, Stal., and apparently 

 includes the Pycanum wcstivoodii, Voll., a species only 

 known to me by its figure. 



Sanganus Jenseni, sp. n. (Plate X, fig. 6.)
