AND SPECIES UP GALERUCINIE. 
185 
elytris infra basin leviter transversim excavatis, utrisque plaga basali 
subquadrata, ad snturam et ad marginem abbreviata alteraque pone 
medium subrotundata, nigris. Long. 3 lin. 
Mas. Antennarum articulis tertio, quarto quintoque compressis et diia- 
tatis ; abdominis segmento anali trilobato, lobo intermedio oblongo, 
profunde concavo. 
Ilab. 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 S ; 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 of A. occipitalis differs from the same sex of A. frau- 
didenta , 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. 
14. Aulacophora l^evifrons. Auguste oblonga, postice ampliata, 
rufo-fulva, nitida, antennis flavis, tibiis (basi exceptis) tarsisque piceis 
aut nigro-piceis, elytris teuuiter punctatis, nigris ; thorace vix pone 
medium transversim sulcato, sulco profunde impresso, paullo infra 
marginem lateralem abbreviato. Long. 3 lin. 
Mas. Capitis vertice non tuberculato ; antennarum articulis tertio, quarto 
quintoque incrassatis et ampliatis, difformibus. 
Fern. Antennis filiformibus, abdominis segmento anali apice obtuse 
truncato. 
Var. A, 5- Tibiis tarsisque rufo-fulvis. 
Hab. Java; Singapore (Wallace). 
Vertex and front smooth, not tuberculate, the latter impressed 
just above the encarpae with a deep fovea; antennae in the <$ with 
the basal joint slightly thickened, subclavate, the third joint slightly 
thickened, obconic ; the fourth equal in length to the preceding 
one, rather strongly thickened, slightly compressed, noduiiform.
