266 Mr. G. C. Champion on the Heteromerous Goleoptera 
patch on each elytron. The species approaches 
Laferte's fourth division of the genus, the thorax 
being grooved at the sides behind. 
MicrantMcus, n. gen. 
Elytra connate, abbreviated, leaving a considerable portion of the 
abdomen exposed ; body apterous, very depressed ; the other cha- 
racters as in Anthicus. 
The single minute species from North- West Australia 
referred to this genus seems to me to be best separated 
from Anthicus. The insect resembles a very small 
Dro mills. 
Micranthicus hrachypteruSj n. sp. (Plate VI., fig. 16.) 
Moderately elongate, subparallel, very depressed, shining, gla- 
brous ; pallid testaceous, the eyes black ; the elytra with a large 
triangular scutellar patch, connected behind with a broad median 
fascia, and the apex, brownish (these markings leaving a large 
subtriangular humeral patch and a post-median fascia pale testa- 
ceous). Head moderately large, somewhat orbicular, rather convex, 
very sparsely, minutely punctate, rounded at the sides behind the 
eyes, the latter large and very coarsely granulated ; antennae very 
slender, rather short, the joints moniliform, 11 ovate. Prothorax 
slightly longer than broad, a little narrower than the head, cordate, 
transversely convex in front, flattened on the disc behind, sparsely, 
minutely punctate. Elytra about two and one-third times the 
length, and rather more than one and a-half times the width, of the 
prothorax, subparallel, truncate in front, obliquely truncate behind, 
flat, thickly, minutely punctate. Legs moderately elongate, the 
tibiae and tarsi very slender. Length (to the apex of the elytra) 2, 
breadth 4 mm. 
Hah, N. W. Australia — Adelaide River. 
Two specimens, and others also sent to the British 
Museum. I am unable to detect any external sexual 
distinctions.

MORDELLA. 
Mordella, Linnaeus, Syst. Nat., 10th edit., i., p. 420 
(1758); Lacordaire, Gen. Col., v., p. 609. 
Judging from Mr. Walker^s captures, this genus must 
be represented by many species in Tasmania.
