Since writing the above I have been much grieved to hear of 

 the rather sudden and unexpected death of Professor Blyth, who 

 had broken his leg shortly before we reached Christiania, but 

 was said to be rapidly recovering. — E. S. S.

Florida. — P. schwarzii was described from a large female 

 taken by Mr. Schwarz ; but I have several examples from Mr. 

 Robertson, indicating that the insect varies in size. Mr. 

 Robertson kindly sends me also the male, which is a remark- 

 able insect ; the face-marks are cream-colour, the lateral marks 

 long and narrow, pointed at each end, the inner side squarely 

 truncate a little above the level of the top of the clypeus, the 

 further projection along the orbital margin being narrow. The 

 upper margin of the clypeus is broadly black, and there is a 

 short black median downward projection, and long narrow 

 lateral black stripes, separating the light colour of the clypeus 

 from the lateral marks. There is no supra-clypeal mark. The 

 first abdominal segment is smooth, practically impunctate. The 

 punctuation of the thorax is fine and close, not coarse as in 

 conflaens. Antennae, hind border of prothorax (except spot on 

 tubercles) and tegulse wholly dark. Wings strongly infuscated as 

 in the female. 



In lacking a supra-clypeal mark in the male, this is like neva- 

 densis, but in all other respects that is a totally different insect. 

 It had been formerly questioned whether it might be confluens or 

 elliptica, but it is in fact wholly distinct from either of them. 



I have before me also types of P.floridana, Rob., and P.Jiam- 

 mipes, Rob., both from Florida. 



Louisiana. —In Coll. Am. Ent. Soc. is a small male, which I 

 can only refer to modesta, though one would not look for that 

 species so far south. It is not in the best condition, but it seems 

 to present no good distinctive features. 



Texas. — Three specimens are in Coll Am. Ent. Soc, two in 

 U. S. N. M. Of the former, a male is to be referred to citrinifrons,
