226 Mr. G. C. Champion on the Heteromerous Goleoptera 
Taxes^ n. gen. 
Apical joint of the maxillary palpi stout, triangular, its apical 
and outer sides about equal in length ; mandibles bifid at the tip ; 
antennae slender, short, joint 3 twice as long as 2 and shorter than 
4, the following joints gradually decreasing in length and increasing 
in width, 11 bluntly rounded at the tip ; head short and broad ; 
eyes very widely separated, coarsely granulated ; prothorax strongly 
transverse, bisinuate at the base, with distinct basal foveas ; scu- 
tellum strongly transverse, triangular ; elytra three times the 
length of, and at the sides forming almost a continuous outline 
with, the prothorax ; metasternum short ; legs short and slender ; 
the penultimate joint of the tarsi feebly or obsoletely lamellate 
beneath ; claws pectinate ; body oblong-oval, clothed with very fine 
sericeous pubescence, winged. 
This genus is not very closely allied to any other 
Cistelid known to me. It approaches Hymenorus, Muls., 
and Nocavy Blackb. The legs and antennae are very 
short, and the penultimate joint of the tarsi is obsoletely 
or feebly lamellate beneath. The two species referred 
to it have somewhat the facies of a small Alphitohius, 
I am unable to detect any external sexual characters. 
Taxes depressus, n. sp. (Plate VI., fig. 3.) 
Oblong-oval, depressed, shining, pitchy -black, partly ferruginous 
beneath ; the legs and antennae piceous or pitchy-brown, the basal 
joints of the latter sometimes ferruginous, the knees and the tarsi 
testaceous ; above and beneath rather sparsely clothed with a short 
fine griseous pubescence ; the entire upper surface very closely, 
finely punctate, the punctures more crowded upon the head than 
elsewhere, the lower surface more sparsely punctured, the propleurae 
rugosely punctured. Antennae about reaching the humeri, the 
apical three joints as broad as long. Prothorax convex, at the base 
more than twice as broad as long, very much wider at the base than 
at the apex ; the sides strongly rounded from the middle forwards, 
almost parallel behind ; the hind angles rectangular. Elytra about 
three and one-fourth times the length of the prothorax, depressed ; 
the sides subparallel to the middle, and thence arcuately converging 
to the apex ; finely punctate-striate, the punctures closely placed 
and distinctly coarser than those of the interstices, the latter 
flat on the disc and convex at the sides and apex. Penultimate 
joint of the tarsi very narrowly and obsoletely lamellate beneath. 
Length breadth l|-2 mm.
