the descending portion only being furnislied with small scat-

40G, C. incisus, n. sp. Praecedenti affini3, sed excavatione abrupte limi- 

 tata, in medio transversim interrupta, parte anteriori augusta, linea lon- 

 gitudinali divisa, parte posteriori triangulari et oblique sulcata, utrinque 

 fere impunctata; lateribus extus grosse punctatis; elytra punctis in sulcis 

 majusculis quadratis; tibiae anticae intus barbatse, baud sulcatae. Long. 

 5-7 mm. 



Hab. Celebes, Beccari; Andai, L. 31. D'Albertis. 



At first sight this species seems almost identical with the above 

 but the remarkable sculpture of the prothorax at once distin- 

 guishes it. What appears to be the other sex ( c/"?) is much nar- 

 rower and smaller.

The amount of rufous at the base of the elytra is variable. 



409. C. Albertisii, n. sp. Prrecedenti alfinis sed minor et manifeste an- 

 gustior, prothorax margine basali integer, et raagis sed irregulariter punc- 

 tatus; elytra rufescentes ad suturam et versus apicem gradatim infuscata, 

 et minus grosse punctata, etc. Long. 3-4 mm. 



Hab. Somerset, L. M. D'Albertis. 



A smaller and proportionally narrower form than C. basalis. 

 In some examples the rostrum is smooth, finely and sparsely 

 punctured, in others it is so closely and coarsely punctured as 

 to give it a rough appearance. The difference is evidently sexual 

 and must be taken into account when only one specimen is 

 available.
