OBSERVATIONS, ETC. 43 



delicately punctured on the head and thorax, and is shining, 

 and covered with a fine glittering silky pubescence ; Dr. 

 Roger says the maxillary palpi are one-jointed, in P. con- 

 tracta they consist of two joints. 



Aporus unicolor (Fam. Pompilidce). A specimen of 

 the female, of this extremely rare species, was taken in 

 x\ugust, by Mr. B, Newcomb at Dartford in Kent. 



Miscoplius 7naritimiis (Fam. Larridce). I captured a 

 female of this rare insect at Deal in August last. 



Cerceris lahiata (Fam. Philanthidas). Taken at Dart- 

 ford by Mr. B. Newcomb, who observed that it stored up 

 various species of CurculioJiidce for the food of its larvsB. 



Cerceris emarfjinata. In my remarks upon the species of 

 this genus, in the monograph of the fossorial Hymeno-ptera, 

 page 189, I remarked, " Five species have been discovered 

 in this country, and a sixth may probably be added, the 

 Philanthus emarginatus of Panzer ; four specimens are in 

 the collection of British Hymenoptera in the British 

 Museum, but there is a want of certainty as to the locality 

 from whence they came." Since the publication of these 

 remarks, I have discovered,*in a register in the Museum, a 

 list of insects captured in Devonshire by Dr. Leach, and pre- 

 sented by him to the national collection ; these insects have 

 numbers attached which ag-ree with those of the reo^ister; this 

 circumstance would alone appear sufficient to warrant their 

 introduction into the British list, but all doubt of the propriety 

 of such a step, is removed by the fact of my having captured 

 a female in August last, at Kingsdown near Deal. 



Prosopis variegatus (Fam. Andrenidce). Having recently 

 received males of this species from Dr. Sichel, of Paris, 

 that sex having been only recently discovered, it has been 

 thought desirable to give some illustrations of the differences
