genera and species of Langurndce. 309 



provisionally in the present state of our knowledge. I 

 am enabled to do this through the kindness of Mr. G. 

 Lewis, who has handed over to me for the purpose his 

 collection of Languriidcs from Ceylon, nearly the whole 

 of which consists of examples of this genus. 



Motschulsky's description of the genus is as follows : 

 — " Tetramere de forme intermediaire entre Lissonius et 

 Languria. Corselet convexe anterieurement, un peu 

 retreci en arriere, angles posterieurs droits ; elytres 

 allongees, retrecies a la base et attenuees vers I'extremite, 

 striees par des points imprimes; ecusson quadrangulaire 

 et acuminee posterieurement ; antennes surpassant en 

 longeur la base du corselet, un peu moniliformes, a 

 massue des trois articles. Dernier article des palpes 

 acuminee; tarses assez larges, le troisieme bilobe." 



As a matter of fact the posterior angles of the thorax 

 are rather acute and produced, more so in the female 

 than the male ; in all probability Motschulsky formed 

 his description from the latter sex. 



Cladoxcna maculata, Mots. 



Motschulsky's description of this species enables it easily to be 

 identified: — "Elongata, sublinearis, thoracis elytrorumque basi 

 subangustatis, convexa, nitida, cupreo-aenea, elytrorum maeulis 

 utrinque in medio tribus alteraque oblonga postice pedibusque 

 rufo-testaceis, elytris distincte punctato striatis. L. li lin." It is, 

 however, incomj)lete, and is made from a small specimen : the head 

 and prothorax are strongly puuctm-ed, aeneous or metallic-blue, 

 the latter being either unicolorous or with more or less testaceous 

 margins; in the female it is convex, rather strongly rounded in 

 front and sinuate behind, with aciitely projecting angles; in the 

 male subquadrate and less convex, with posterior angles less acute ; 

 the elytra are broader at base than base of prothorax, with shoulders 

 well marked and callose, with rather strong rows of punctures ; 

 sides gradually narrowed to apex ; apices rounded and callose ; 

 aeneous, with margins and often apex, two spots on each elytron, 

 and two oblong patches near suture, yellow ; these spots are some- 

 what variable; antennte red, with abruptly three-jointed club, 

 which is often darker ; legs long, testaceous ; tarsi, and sometimes 

 femora partly, fuscous; under side reddish or reddish aeneous. 

 L. 3t — 5 mm.
