was not uncommon, being found chiefly at rest on fences, and 

 easily taken b}- hand without the aid of a net. Two speci- 

 mens of En'stalis vinctoniui Fabr. were captured, one of 

 them being taken from the clutches of the Asilid mentioned 

 before. Of the Hymenoptera, we might mention Stiziis 

 Jwgardii. Latr., a very fine wasp, reddish in color, with smok}' 

 wings, the tip of the abdomen black; a small species of Pom- 

 p/'his: a female example of Sfhcprofhthalmaferrug-ata Fabr., 

 which occurs also as far north as New England; and a female 

 Evania appoidigastcr Linn., a curious insect of a deep black 

 color, the small subtriangular compressed abdomen appearing 

 out of all proportion to the heavy thorax. "i 



The following interesting account of pelagic Ilemiptera is 

 quoted from an article by Mr. Wickham that appeared in 

 ••The Entomological News." February, 1894: 



On the second of Julv, \\iiile at anchor near the Sand Key Light, a few 

 Iliilobtifes ^vere seen near the ^ essel between three and four o'clock in the 

 afternoon. By getting into a boat which ^\ as l>ing alongside, no difficulty* 

 was experienced in capturing two or three that came within reach of the net. 

 The next day, while the vessel was under way with quite a pleasant breeze, 

 they Avere seen again, before seven o'clock in the morning, skimming 

 about the bows. Two or three were again taken by sitting in the chains 

 under the bow-sprit and "jabbing "at them with a ciab-net lined with bolt- 

 ing cloth, as often as one crossed our course. By eight o'clock they were 

 le.'-s numerous. ^Vith the aid of the Report, pre\iously mentioned, they 

 were determined as Ilalohatcs -viillerstorffi Frauenf. a name afterwards 

 %erilied by Mr. O. Heidemann, of Washington. 



The following day more of them were seen in I^at. 24° 24' X., Long. 70' 

 49 \V. Immediately after dinner, when the water was still, except for a 

 smooth swell, a specimen was caught in a crab-net and turned loose, with- 

 out ]>eing touched by the fingers, into a tub of salt water on the deck. The 

 insect at once commenced to scud around on the surface with movements 

 so rapid that the eve could not follow them, and any ob-ervations on the 

 mode of locomotion were out of the question. In a few minutes partial 

 exhaustion succeeded these violent exertions, and it was then seen that the 

 long middle pair of feet did nearly all the work of progression, the anterior 

 pair being carried folded up (nearly) and projecting forwards, a little to 

 each side of the head. The antenna; point forwards and outwards, form- 

 ing a V- When the bug tires, the muscles at the insertion of the legs 

 appear to weaken first, and the body is let down on to the water. It there 

 rests in very much the position shown in Mr. Walker's figure in the "Entom.
