lateral margins of the pronotum are well developed. The metaster- 
num is not punctured in the middle. The abdominal sterna are 
also less uniformly punctured than in V. dawnae. 
The basal piece of the genital tube is furnished with an elongate 
triangular mid-ventral lamella between the lateral lobes. Each of 
these lobes is strongly concave on the inner side, and is furnished 
with a large inwardly directed ventral lamina. Together these 
structures form an imperfect sheath in which the median lobe and 
the base of the internal sac are hidden. The exposed portion of 
the latter is ribbon-like with a rounded extremity; the terminal por- 
tion, though supported by the chitin accompanying the ductus ejacu- 
latorius, is composed apart from this of a curious cellular material 
which when dry resembles dried vegetable tissue. The armature is 
confined to the region immediately preceding this terminal portion. 
Although the internal sac is permanently evaginated, as in the pre- 
ceding species, it lies with the remainder of the genital tube inside 
the internal abdominal segments when at rest. 
In other respects this species resembles H. dawnae. 
Nigidius distinctus, Parry. 
Bengal: Duars—Maindabari, Buxa Division (¢@ @ ). 
Upper Burma: N. Shan States—Hsipaw* ( ? ). 
Mr. Beeson has sent me eight males and four females of what 
I take to be Nigidius distinctus from Maindabari. In both sexes 
there is some variation in the proportion of length to breadth, and 
in the puncturing. The specimens agree as well with Fairmaire’s 
description of N. oxyotus from Tonkin (Ann. Soc. Ent. Fr. (6) VIII, 
1888, pp. 339-340) and Boileau’s description of N. biymanicus from 
Rangoon (Trans. Ent. Soc. London, 1911, pp. 446-449) as they do 
with Parry’s description and figure of N. distinctus (Trans. Ent. 
Soc. London, 1873, pp. 341-2, pl. v, fig. 7); and I am unable to 
distinguish them from the specimen from Hsipaw in the Dehra Dun 
collection. ‘fhe Hsipaw specimen is unfortunately a female, and I 
have been unable to examine the male genitalia of any Burmese 
or Malaysian specimens. Possibly they might afford distinctive 
characters as in the two species described above. 
Nigidius impressicollis, Boileau. 
Assam: Khasi Hills—Maflong, 5900 ft. (@ 2). 
Adults and larvae of this species were found by Mr. S. W. 
Kemp in damp and thoroughly soft and rotten wood. ‘The sexes 
are scarcely distinguishable externally.
