24 Records of the Indian Museum. [Vol. XIY, 



I think I have identified this species correctly. The description 

 given by Distant is very meagre. Douglas and Scott in their " British 

 Hemiptera '' have, however, given a more detailed description with which 

 the specimens agree fairly well. 



The only other example in the collection of the Zoological Survey 

 has abbreviated elytra ; it was taken in Palestine and was determined 

 by Horvath. 



Gerris spinolae, Leth. and Sev. 



Of this very abundant species only a few specimens were obtained, 

 viz., two specimens from a swamp at the head of the Inle Lake, Yawnghwe 

 State, 20-ii-1917 ; two from the canal at Than-taung, Yawnghwe 

 State, 28-ii-1917, and eight from the Inle Lake, Yawnghwe State, 

 3,000 ft., 18— 28-ii-1917. 



Ptilomera laticaudata (Hardw.) 



Ptilomera laticaudata. Distant, Faun. Brit. I ml., Rhyn. II, p. 185. 



Six specimens from Taung-gya Valley, Yawnghwe State, ca. 3,500 

 ft., 2-iii-1917 ; two specimens from Than-taung, Yawnghwe State, 

 ca. 3,000 ft., 28-ii-1917. " Not uncommon on jungle streams in 

 Burma, the Malay Peninsula and Siam ; markedly gregarious. N. A.'*

(Plate VIIL, fig. 3.) 



Described from one pinned and several alcohol specimens from the 

 Taung-gya Valley, Yawnghwe State, ca. 3,500 ft., 2-iii-19l7. 



Ochraceous with numerous black markings which are sometimes 

 more or less reduced or almost absent. Most of these markings are 

 densely covered with fine greenish pubescence. Head with the apex 

 black (seen from beneath), with a silvery white pubescent s|)ot on each 

 side ; a large V-shaped mark on disk of vertex, a small marginal spot 

 on each side before eyes and a slightly curved fascia on the posterior 

 area near the inner margin of each eye, black. 



Pronotum with four black spots or marks ; two discal, which are 

 largest and converge on the anterior margin, and two smaller, lateral, 

 submarginal, touching the anterior margin. 



Mesonotum very large, more than twice as long as the pronotum. 

 A large harp-shaped mark on disk, anteriorly clothed with greenish 

 and posteriorly with bluish-grey pubescence ; on each side of this is a 

 lateral curved fine extending from the anterior margin to about the 

 middle of disk, a short broad band connects this with another curved 

 line, the inner part of which extends to the base of the mesonotum, 

 with the outer portion reaching the region of the intermediate acetabula. 

 Abdomen blackish above, the three apical segments medially ochraceous. 

 Connexivum marked with ochraceous. 



Antennae piceous, basal joint ochraceous. Legs ochraceous, tarsi 

 black.
