beyond the middle, the posterior lateral angles are slightly 
prominent. The elytra are subovate, convex, setose, 
covered with oval punctures, considerably smaller than 
those of the pronotum, with two or three very slightly 
marked slender costa on each. The anterior tibiz are 
very broad, and bidentate at the tips, with two smaller 
teeth on the middle of the outer edge. 
Lissotes Howrrranus, Westw.* 
(Plate IX. fig. 7a, b, c, d.) 
Dr. Howitt having been so kind as to send me speci- 
mens of both sexes, of this very remarkable species, from 
the alps of Victoria, I am enabled to supply the omissions 
in my original description, by giving the characters of 
the female, and illustrating the parts of the mouth of both 
sexes. 
The female is as large as the male, being one inch and 
two lines long; glossy black; the head is much smaller 
than that of the male, and much narrower than the pro- 
thorax, it is strongly swollen on each side behind the 
eyes, the upper and under portions of which are entirely 
separated by the canthus (as in the male); the front of 
the head slopes down gradually, forming a large semi-

The genus Lissapterus of Deyrolle, to which this insect is assigned by 
Major Parry in his last Catalogue of the family, must be unpublished, 
since I am unable to find any such, either in his Memoir in the ‘ Ann. de 
la Soc. Ent. France,’ for 1864; or in the ‘Ann. Soe. Ent. Belge,’ for 1865, 
vol. ix. From the name, it may be inferred that, the apterous condition 
of D. Howittanus had induced its generic separation, but, both sexes 
of L. obtusatus, and as we have seen above, the male of L. Launcestoni 
(which cannot be separated from the other Australian species) are desti- 
tute of wings. A more important character, namely the unarmed condi- 
tion of the inner lobe of the maxille of both sexes of D. Howittanus, as 
well as the singular cucullated head of the male, might suffice for the 
establishment of a separate generic group, but they seem outweighed by 
the identity in the general characteristics of the species. The inner lobe 
of the maxilla is also destitute of a hook in L. crenatus (see Trans. Ent. 
Soc., n. s., vol. 3, pl. xii. £. 3b).
