1915.) S. MAvULIK: Cryptostomes of the Indian Museum. 375 
five species are all from the Indian region. The Indian forms 
differ from the type in the following characters :— 
(rt) The long dorsal spine of the first joint of the antenna is 
not bent forward. 
(2) 3-6 joints of the antennae are not dilated as in H. atra, L. 
(3) The tibiae are not dilated as in H. atra, L. 
The middle tibiae in the Indian forms are curved, which is not 
so in the case of H. atra, L. 
The differences of the characters between the type and the 
Indian forms, the homogeneity of those of the Indian forms, and 
the fact that H. atra, L. is found in the temperate zone, all point 
to the conclusion that the Indian forms may be separated and 
formed into a new genus. On the other hand it may be pointed 
out that a slight gradation in the characters is noticeable in the 
Indian forms. Ido not, therefore, propose to separate them at 
present, unless more material from the Indian region establishes 
this fact beyond doubt. 
Instead, for the sake of convenience, I shall characterise the 
genus as follows :— 
Antennae.—1-6 joints spiny, 3-6 may be dilated, apical 5 
joints forming a club. 
Claws.—Completely separate. 
Tibiae.—Straight, dilated or not dilated, middle tibiae may 
be curved. 
A table will distinguish the forms thus :— 
I. 3-6 joints of antennae dilated (flat- 
tened) i as Gln. 1). 
2. 3-6 joints of antennae ae dilated eS 3 
3. Antennae short, stout, Ist joint with 5 
dorsal spines .. brachycera, Gestto. 
4. Antennae long, slender, ist joint with 
less than 5 dorsal spines 5. 
5. Ist joint of antennae with 4 dorsal 
spines, 2nd joint with 2 dorsal spines stygia, Chapuis. 
6. Ist joint of antennae with less than 4 
dorsal spines 7. 
Fania joint of antennae with 3 dorsal 
spines, 2nd joint with 1 dorsal spine ramosa, Gyll. 
8. Ist joint of antennae with 2 dorsal 
spines, one very minute .. andrewest, Weise. 
Owing to the reasons stated by Weise (Deut. Ent. Zeit. 1897, 
p. 127) I do not include Motschulsky’s species ceylonica in this 
table.
