them in the middle are placed two short erect teeth. Underside of

" $ . Length 9 mm. Similar to the , but the prouotal spines 

 are like triangular short teeth ; the mesonotum in front is finely 

 rugose and in the middle, like the scutellum, studded with neat 

 rounded punctures ; the spines of the metanotum are shorter, 

 stouter, with the apex only a little bent outwards. Also the 

 spines on the node of the pedicel are somewhat shorter than in 

 the . The wings are brownish, the nervures brown." (Roger.)

. Kesembles P. arachne, Emery, in the shape and disposition 

 of the metanotal and pedicel spines, but differs from that species 

 considerably in sculpture and in the pronotal spines being stouter 

 and more erect. Black ; the head and thorax very finely and 

 delicately punctured, rugulose, opaque ; abdomen smooth, not 

 shining, with a thin covering of very fine silky yellowish pile, and 

 on the apical segments a few short erect hairs. Pronotal spines 

 stout, pointing slightly forward, upward and outward ; metanotal 

 and pedicel spines as in P. arachne. There is a distinct transverse 

 gibbosity on the thorax at the meso-metanotal suture, and the 

 abdomen is longer and more massive than in the above-named 

 species. 



Length, $ 6-7 mm. 



Hab. Tenasserim, Moulmein, Papun. 



I found this species in the forests on the Tunzalin river, near 

 Papun, fairly common, nesting like P. arachne in the hollow joints 

 of bamboos. In Mr. Wroughton's collection there are specimens 

 collected by Mr. Hodgson of the Forest Department, labelled 

 Moulmein.
