374 Recoyds of the Indian Museum. [Vol,. XXIV. 



This species seems to be one of the most widely spread, and 

 perhaps one of the commonest of the Indian Gomphines. I have 

 not seen specimens from Assam or Burma. A closely allied 

 species or race, I. fallax Selys, is known from Shanghai. 



Ictinus angulosus Selys. 

 i<3. Dum-Dum, near Calcutta, 4-vi-n (6371/20). 



Face entirely yellow save for fine black lines below the ante- 

 clypeus and above the post-clypeus. A fine yellow line on the 

 exterolateral surface of the middle pair of tibiae. The yellow 

 markings, especially on the thorax and on segment 10, have a 

 distinct red tone. Inter-alar spaces largely yellow, with a trans- 

 verse black line between the wing-bases. Otherwise the specimen 

 agrees with the description given of the type. 



I,ength of abdomen 54 + 2*25 mm., of hinder-wing, 42 mm. 



The species seems to me to be very near atrox Selys, of 

 which only the female is known. Both are rare in collections, 

 and I have not seen an example of atrox, nor the female of 

 angulosus. I suspect the two are conspecific. 



Genus Gomphidia Selys. 



Genotype : G. T-nigrum Selys. 

 Species examined : G. T-nigrum Selys. 



A genus of large and handsome insects, very similar in 

 general to Ictinus, but readily distinguished by the absence of any 

 leaf-like lateral expansions on the eighth abdominal segment. The 

 members of the genus appear to be rarer insects of rather more 

 restricted distribution than are the species of Ictinus. All are 

 peculiar to the Oriental Region, and most of them are found in 

 Malaya. G. T-nigrum is the only species recorded from within the 

 limits of the Indian Empire. The larvae breed in tanks and still 

 waters, thus differing from those of Ictinus which breed in running 

 water (Fraser). 



Gomphidia T-nigrum Selys. 



2($ <$, 2? $. Poona, May, 1917. F. C. Fraser. 

 Recorded by de Selys as coming from the ' North of India.' 

 The species, hitherto regarded as rare, is evidently fairby abun 

 dant near Poona, at any rate seasonally. 



length of hinder-wing of & 38 mm., of abdomen 50 mm. + 4 

 mm. 



Series Epigomphus (Williamson). 



Characterized by free triangles, subtriangles and supra-tri- 

 angles, and by the existence of more than two cross-nerves be- 

 tween Mx_ 3 and M 4 in the hinder-wing. These cross-nerves are 

 not widely spaced from one another as in the next series. Fork- 

 ing of M1-2 and M 3 usually unsymmetrical.
