COLTDIIDJE OBTAINED IN CEYLON. 131 



This little insect will be readily distinguished, so far as one sex 

 is concerned, by the unusual development of the middle and hind 

 tibiae ; the species has also the front coxae more approximate than 

 they are in the normal species of the genus. The middle tibise 

 have at the apex an acute mucro internally, while the hind tibiae 

 have an angular incrassation. 



Dikoya and on the Horton plains ; six specimens. 



Certlon qtjadeicolle, n. sp. 



Oblongum, depressum, rufo-testaceum, nitidum ; prothorace quadrate, 

 crebre sat fortiter punctato ] elytris simpliciter striatis, striis ad basin intus 

 curvatis. Long. If millina. 



Antennae short, moderately stout ; eyes small. Thorax nearly 

 as long as broad, straight at the sides, emarginate in front so that 

 the anterior angles are prominent, the surface rather coarsely 

 and moderately closely punctate. Elytra deeply striate, but tlie 

 striae not punctured, distinctly curved inwards at the base ; inter- 

 stices broad, not punctate. Under surface very little punctate. 



This species agrees with G. tibiale in the comparative slight 

 separation of the front coxae ; the curved striae exist also in C. 

 pusillum, Pasc, which species, however, has the sides of the 

 thorax rounded. 



Point de Gralle ; two examples. 



Ceetlon obientale.
