356 DESCRIPTIOXS OP NEW SPECIES OF AUSTRALIAN COLKOPTERA, 



abdomen is paler) ; the head is moderately infuscated on the basal half and paler 

 in front, but the shades of colour are not sharply defined; the antennae are 

 almost uniformly infuscated throughout. One female has the head uniformly in- 

 fuscated, but otherwise its colours are as those of the type; a second female has 

 the head entirely pale, and elytra much less deeply infuscated. Regarding the 

 head as pale the species, in my table, would be associated with H. anticus and 

 H. geniculatus, which have sides of prothorax very different and much smaller 

 eyes; regarding the head as dark it would go with the allies of H. pusilluSj from 

 aU of which it is at once distinguished by the very large eyes; thus on the male 

 of G. pusillus the combined width of both eyes is less than half the width of the 

 intervening space, on the present species each eye is more than half the width of 

 that space, and its length is about equal to the combined lengths of the second 

 and third joints of antennae; the sides of the prothorax are much as in H. denti- 

 collis and //. angustus, whose eyes are much smaller. 



HyPATTALUS CRIBRIPENNIS, n. Sp. 



c?. Black; labrum, prothorax, parts of under surface of three basal joints 

 of antennae, and trochanters flavous. Moderately clothed with short, erect, dark 

 hairs, and with sparse, ashen pubescence. 



Head gently convex, slightly depressed in front. Antennae rather long, 

 third to tenth joints obtusely serrated, seventh joint slightly longer than the 

 adjacent ones, and about equal to eleventh. Prothorax widely transverse, sides 

 widely rounded and with the base obliquely margined, a shallow depression near 

 base, and a still more feeble one near apex; with a few scattered punctures. 

 Elytra parallel-sided to near apex, sides and suture slightly thickened, the api'X 

 more distinctly so; with crowded, sharply defined punctures, a few of which are 

 confluent. Legs moderately long. Length (d", ?), 5-5.75 mm. 



2. Differs in ha\'ing the head smaller, with two feeble foveae in front, eyes 

 smaller and less prominent, antennae shorter and less strongly serrated, apical 

 joint of palpi smaller, apex of elytra scarcely thickened, legs somewhat shorter, 

 and clothing of upper surface sparser. 



Hab. — Tasmania: Waratah (A. M. Lea). 



At first glance much like many species of Ueteromastix but with exsertile 

 vesicles. In my table (I.e., p. 169) would be placed with H. abdnmitialis, which 

 is a much smaller species, with blue elytra, etc.; //. longicornis lias bluish elytra 

 and much longer and less strongly serrated antennae; the female in general ap- 

 pearance is somewhat like a large female of //. triangidiferu^, but the antennae 

 are less strongly serrated, and more of the head is dark. A female, from Mount 

 Wellington, probably belongs to this species, but has the frontal foveae more 

 conspicuous, and elytra with a faint purplish gloss. 



Htpattalus apiciventris, n. sp. 



c?. Black ; nuizzle, parts of four or five basal joints of antennae, basal 

 joints of palpi, prothorax, and base of femora flavous. Witli spai-se and 

 minute, ashen pubescence. 



Head moderately convex between eyes, slightly irregularly concave in 

 front ; with small, scattered punctures, becoming denser at base. Antennae 

 moderately long and feebly serrated, second joint small, third and fourth not 

 much larger. Protlwrax strongly transverse, base finely margined, basal half
