Heinelvtra dull fuscous black with numerous greyish- white spots : a 

 very large spot interrupted with fuscous occupies nearly the whole of the 

 clavus ; corium with a small and a large basal marginal spot ; a large, 

 centrally infuscate spot near inner margin, a smaller one near outer 

 margin : an elongate irregular subapical membranal spot, and a smaller 

 elongate spot at inner angle. Body beneath black. Legs hairy, brownish 

 ochraceous, darker towards the apices of the femora, tibiae and tarsi. 



Length 1-9—2 millim. 



In addition to the Shan specimens I have examined a number ob- 

 tained bv Dr. Gravely on the road from Thingannyinaung to Myawadi. 

 Tenasserim, ca. 900 ft., 24— 26-xi-19U. 



Type No. 7106/H. I. in the collection of the Zoological Survey of 

 India.

There seems to be some doubt about the identity of this species. 

 The genus was orginally described from an apterous form by Fieber, 

 in a very vague manner. Later on Kirkaldy defined it more fully and 

 made P. breddini, a Javanese species, the type of the genus, the descrip- 

 tion being taken from an apterous form also. Bergroth described a 

 macropterous form and placed it in this species. The only Burmese 

 form as yet recorded, P. rufus, Distant, was described from an apterous 

 insect. Dr. N. Annandale,^ however, described a winged form from a 

 small tributary of the Rangoon River, Burma, as that of P. rufus. 

 The specimens from the Shan States, which are all winged, agree with 

 the one described by Dr. Annandale as well as with Bergroth's de- 

 scription of P. breddini from Java, and apterous specimens from Sukli, 

 east side of the Dawna hills, ca. 2,100 ft., Burma, agree with apterous 

 specimens in the collection identified by Distant. Among those from 

 Sukli there are also some winged forms which are exactly similar to the 

 Shan ones. It seems probable that these all belong to one species, and 

 as P. breddini was described before P. rufus, the Shan specimens must 

 be placed under the former name. 



A number of adult specimens were obtained from a small pool in 

 the bed of a dry stream at He-Ho, ca. .3,800 ft., Yawnghwe State, 

 7 — 9-iii-1917 ; three specimens in the Taung-gya Valley, cor. 3,500 ft., 

 2-iii-1917, and six from Fort Stedman, ca. 3,500 ft., Yawnghwe State, 

 3-iii-1917. The species is common on small pools in streamlets in 

 the State of Yawnghwe and also in the Dawna hills. The genus appears 

 to be practically confined to a habitat of this kind.
