elytris infra basin leviter transversim excavatis, utrisque plaga basali 



subquadrata, ad suturam et ad inarginem abbreviata alteraque pone 



medium subrotundata, nigris. Long. 3 lin. 

 Mas. Antennarum artieulis tertio, quarto quintoque compressis et dila- 



tatis ; abdominis segmento anali trilobato, lobo intermedio oblongo, 



profunde coneavo. 

 Sab. New Guinea, Dorey ; Bouru (Wallace). 

 Vertex with two large black patches, divided in the median line 

 by a flavous line ; antennae with the third, fourth, and fifth joints 

 compressed and dilated in the ; the third twice as long as 

 broad, narrowly cuneiform, the fourth shorter and more strongly 

 dilated than the third, trigonate, its antero-external angle pro- 

 duced, very acute ; the fifth still shorter than the fourth, subtri- 

 gonate. Thorax about one half as broad again as long; sides 

 sinuate, subparallel, slightly produced just beyond the middle, 

 thence obliquely converging towards the apex ; disk impressed 

 across the middle with a deep sulcation. Elytra faintly excavated 

 below the basilar space, nitidous. 



The (5 oi A. occipitalis differs from the same sex of ^./"nm- 

 dulenta, Jac, in the absence of the frontal tubercles, and in 

 the different length and shape of the dilated joints of the 

 antennae, also in the black patches on the vertex, and in the 

 black breast and abdomen. The females of both species are 

 unknown to me.
