with the length of the tibiae ; the tarsi, too, in tincta are distinctly 

 spined, which is not the case with P. malayana. 



Head opaque ; the cheeks and clypeus covered with silvery pubes- 

 cence, the front and vertex sparsely covered with longish pale hair ; 

 the apex of the clypeus rounded, the sides at the base not sharply 

 oblique ; the palpi testaceous ; the hinder ocelli are separated from 

 the eyes by a distinctly greater distance than they are from each other. 

 Thorax thickly covered with a silvery pile; the scutellumand median 

 segment more sparsely with fuscous hair. The median segment 

 has a gradually rounded slope, is closely obscurely transversely 

 striated in the middle ; the oblique furrow ou the mesopleurae is 

 narrow but distinct ; its lower part at the base is depressed, clearly 

 separated from the rest, and more strongly punctured. Legs 

 pruinose, the four anterior femora more or less obscure reddish 

 beneath, the hinder femora bright ferruginous, except at the 

 extreme apex ; the hinder tarsi are much longer than the tibiae, 

 which are almost spineless. Wings clear hyaline ; the stigma 

 fuscous ; the nervures darker ; the 2nd cubital cellule at the top 

 and bottom is distinctly, but not much, shorter than the third ; 

 the first and second transverse cubital nervures are roundly curved, 

 the first is distinetl}^, the second scarcely oblique; the first reemTent 

 nervure is received in the middle, the second distinctly in front of 

 the middle of the cellule ; in the hind wings the transverse anal 

 nervure is received distinctly in front of the cubital. Abdomen 

 pruinose, shining ; the segments are testaceous at the apex.]

Antennae densely pruinose, like the body. The eyes distinctly 

 converge above, where they are separated by nearly the length of 

 the 3rd antennal joint ; the hinder ocelli are separated from each 

 other by the same distance as they are from the eyes ; the front 



thickly coyered with silvery pubescence. Mesonotum closely punctured, the 

 middle in front slightly raised ; from the base of the tegulis runs an oblique 

 narrow furrow. The postscutellar region is closely and finely, at the base 

 towards the apes more strongly transversely striated. Median segment with a 

 gradually rounded slope ; opaque, finely transversely granular ; the middle and 

 apex thickly covered with long white hair. The middle of the propleura raised ; 

 the lower part triangularly depressed ; the mesopleuras granular, opaque ; the 

 apex on the lower part and the sternum thickly covered with long white hair ; 

 the base of the metapleurce obscurely obliquely striated. Legs longish ; the 

 apex of the fore femora, tlie fore tibias, and the greater part of the tarsi, the 

 apical two-thirds of the middle femora except at the extreme apex, the middle 

 tibiie except behind, the hinder femora except at the base, and to a less extent 

 at the apex, red. Wings hyaline, but with a uniform fuscous tinge ; the 2ud 

 and 3rd cubital cellules are subequal at the base and apex above and beneath ; 

 the first recurrent nervure is received near tlie middle, the second shortly before 

 the basal third of the cellule. Abdomen pruinose ; the apical segment above 

 white, fuscous at the apex.]
