Oxybelus mucronatus. — Several $ and one ? on thistles, Euphorbia, &c, c 

 the Sandhills to the West. 



Oxybelus mandibular is. — One $ in the same locality as the last. This is tl 

 first recorded capture of the ? in England. Mr. Bridgman, Mr. Dale, and myself 1 

 have all taken the $ . 



Prosopis dilatata. — This rare species was not uncommon on Euphorbia flowers 

 on the Sandhills to the West. The ? was much more abundant than the <$ , I 

 expect I was too late for the latter sex. 



JEpeolus productus, Thorns. — I took one ? of this addition to our British 

 fauna on the Sandhills to the West of the Island. On getting home I find I have 

 two £ and one $ of the same species from Littlehampton, taken in a very similar 

 sandy locality. It is rather larger than variegalus, and has the labrum in front 

 sharply bidentate, and the tubercles on its disc nearer the middle than in that 

 species. It also has two distinct round spots on each side of the second, third, and 

 fourth abdominal segments. I hope to describe this species more fully in a coming 

 number with several other new species that I have to bring forward. 



After leaving Hayling Island I went to Bournemouth for a fortnight, but did 

 not succeed in capturing any of the great rarities for which the place is celebrated. 

 Everything seemed very much parched up, and Hymenoptera were 'certainly scarce 

 in places were one would have thought that they would have abounded. I do not 

 remember ever seeing localities so promising and which yielded so little when 

 worked. The following are amongst my best captures : — 



Mutilla europoea. — One o" and a few $ , the <? taken basking in the sun on 

 a bramble leaf about 9 a.m. 31. rufipes. — One ? . 



Pompilus chalybeatus, $ and $ ; several. 



Harpactus tumidus. 



Oxybelus mandibular is, $ . — On the Sandy Cliffs near Boscombe. 



Eumenes coarctatus, off Rubus. 



Andrena pilipes, $ $? , A. austriaca, $ , A. decorata, ? , off Rubus. A. 

 nigriceps, ? , A. tridentata, $ , off Senecio. A. fidvescens, ? , off Crepis. A. 

 argentata, $ , abundant, skimming over the ground in Alum Chine, but I could 

 neither find the ^ nor the parasitic Nomada bavcata — I presume that I was too 

 early in the year for the former. 



Halictus prasinus. — Several $ on Erica, but I was too early for the 3 . 



Dasypoda hirtipes, S 9 • — Pretty common. 



Cilissa tricincta, $ $ . — Pretty common. 



Rombus Schrimshiranus, ? $ . — Occasionally on the heaths and in the chines, 

 but I was unable to get the $ . — Edwabd Saundees, Holmesdale, Upper Tooting : 

 August 11th, 1881. 



A brief notice of Carl Ludivig JDoleschall, the Dipterologist. — My interest in 

 the author of the " Bijdrage tot de Kennis der dipterologische Fauna van Neder- 

 landsch Indie " was aroused by my studies of the fauna of the Malay Archipelago ; 

 however, all that I knew r , until recently, about the circumstances of Doleschall's life 

 was derived from the following sources : 



1. The brief datum in Hagen's Bibliotheca : " Died 1859, in Amboina, Physi- 

 cian in Java." 2. Two short paragraphs in A. R. Wallace's Malay Archipelago
