74 Records of the Indian Museum. [Vou, 28; 
Eugavialidium saussurei, sp. nov. 
Similar to the preceding. Ferrugineous. Vertex subequal 
in width to one of the eyes, on either side dentate, barely eleva- 
ted. Dorsum of pronotum above barely rugose, coarsely granu- 
late; median carina of pronotum before the humeral angles pro- 
vided with three small tubercles and also tuberculate backward 
as far as the base of the hind process ; humeral angles very ob- 
tuse ; posterior angles of the lateral lobes of the pronotum little 
acute triangulate produced outwards, not spined ; front margin 
of pronotum on either side of the lobes bearing a small tubercle ; 
wings fully explicate reaching nearly to the apex of process ; ante- 
rior and middle femora little compressed, margins undulate ; pos- 
terior femora stout, marigns crenulate otherwise unarmed; hind 
tibial margins dentate, very moderately expanded toward the 
apices ; first articles of the hind tarsi not at all expanded, narrow, 
the first pulvillus very small, the second and third longer and 
equal in length. 
Entire length of male 20 mm.; pronotum Ig mm. ; posterior 
femora 7°5 mm. 
Habitat.—Calcutta, India. 
This species like the preceding is labelled, ‘‘ Gavialidium 
philippinum, Bol.,’’ by Saussure. It is allied to E. angulatum, 
Hanc., but differs in the tuberculate median carina of the pronotum 
and as shown in the table of species. ‘This species as well as the 
preceding somewhat resemble members of the genus Gavialidium 
in the dentate character of the vertex, but the lateral carinulae on 
each side are not elevated above the eyes.

Gavialidium crocodilus, Saussure. 
Sauss.. Ann. Soc. Ent. France, iv, p. 481, 1861; Bol., Ann. 
Soc. Ent. Belg., xxxi, p. 219, 1887; Hanc., Spol. Zeylanica, 
ii, pp. 122, 123, pl. 2, fig. 11, 1904; Hanc., Gen. Ins. Orth. 
Acrid. Tetr., pp. 22, 25, pl. 2, fig 16, 1906. 
Habitat.—Peradeniya, Ceylon; Pundaluoya, Ceylon. 
One of these examples is labelled and the species determined 
by Saussure, which helps to authenticate this species. 
In regard to the species Gavialidium alligator, Saussure (Scely- 
mena alligator), its status is in doubt. It appears to me that the 
pupa of crocodilus served as a type for Saussure’s alligator. I 
have a large series of the former species collected in Ceylon by 
Fletcher and Green, which show diverse variations, some being 
smaller than the normal size. From an examination of these speci- 
mens some of the immature pupa agree with the description of 
alligator given by Saussure. I am not sure, but the latter seems 
to be the pupa of crocodilus and therefore is synonymous.
