The female diifers from that of P. longitarsis in its darker colour, 

 blackish antennae and obsoletely trans-strigose metanotum ; 

 P. interstitialis is distinct in the quit^ continuous basal nervure 

 and the lack of a raetanotal subapical carina, though similar in the 

 colour of the stigma, which is shared only \>y P. Icevis. I hesitate 

 to state too definitely thut Cameron's species is synonymous with 

 P. ocdlai'is, since that species is unknown to me ; nevertheless uo 

 doubt can remain that P. ferrugineus bears exactly the same 

 relation to P. longitarsis, Cam. {=testaceus, Grav.), that Thomson 

 describes his species as possessing to P. testaceus, Holmg., i. e., the 

 coloration is paler, the average size is smaller, the ocelli are large 

 and contiguous to the eyes with their region black, the anus is not 

 infuscate, and the mesonotum is somewhat more nitidulous. The 

 stigma, too, appears to be constantly flavous and not fulvous. I 

 iim by no means persuaded that Ivokujew is not right in regarding 

 the present as a mere weakly developed variety of P. testaceus, 

 Grav. 



Lefroy has sent nie a cocoon of this species ; it is cylindrical 

 and equally obtusely rounded at both extremities, pure glossy 

 white, not strongly shining, with a somewhat irregular black band 

 where it begins to contract around both ends and a few irregular 

 black marks on both apices (similar to that of the familiar 

 Casinaria vidua, Grav.). Its length is 11 niillim. and its breadth 

 nearly 5 millim. in the centre. To its apex is affixed an elongate 

 strand, or rather collection of threads, which are still cntirelv 

 flexible, of 33 millim. in length, and connected with the cocoon
