on each ride at the constriction; disk with a longitudinal mesial 

 impression. Bontellum narrowed towards the apex. Elytra long, 

 much enlarged posteriorly; each elytron with four oostee, the Inter- 

 sticcs Bnely and thickly punctured, and with indications of reticu- 

 lation here and there.

Section I. Maxillary palpi very short, thick, compact, the 

 apical joint nearly (/lobular.

Closely allied to C. Scutellaria, Er., but relatively broader ; thorax 

 broader, with a deep mesial impression, broader in the middle ; there 

 is a deep round fovea at the anterior angle, and a deep impression 

 within the posterior angle, the part between the anterior fovea and 

 the posterior impression raised, so that the impressions are not con- 

 fluent as in scutcllaris. The antenna} are broader than in scutettaris, 

 in which the fourth joint is twice as long as broad, whereas in 

 basalis it is not more than one third longer than broad. 



Section II. Maxillary palpi less compactly jointed, the apical joint 



not globular. 



Calochromus melanurus. 



(Plate I. fig. 5.) 



Waterh., Cistula Ent., ii. 1877, p. 196. 



Cyaneo-niger, nitidulus, brevissime pubescens ; thorace medio 

 canaliculato, ad angulos anticos impresso, intra angulos posticos 

 fovea rotundata impresso, basi marginato ; elytris ferrugineo-flavis, 

 dense pubescentibus, prope suturam striatis, interstitiis convexi- 

 usculis, apice nigro. Long. 4|-7| lin. 



Hub. Penang, Java, Sumatra. 



Forehead between the eyes very prominent. Antennas as long 

 as the elytra, the two basal joints shining, the rest finely punctulate. 

 Thorax very delicately and closely punctured, scarcely pubescent ; 

 disk with a fiue mesial line, more deeply impressed behind, there is 

 also a deep impression at each anterior angle ; the posterior angles 

 are rather inflated, and within them there is a deep impression. The 

 elytra are rusty yellow, dull, and pubescent, bluish black at the apex.
