290 Mr Snell, The Natural History of the Island of Rodrigues 



demonstrated the differences between the male P. macaensis and 

 male P. hebraeus. (See Ent. Mo. Mag. (2), vol. xii, 1901, p. 264.) 

 P. macaensis is known also from Seychelles, Amirantes, Chagos 

 (Salomon Islands, Diego Garcia), and Mauritius. 



Scolia (Dielis) grandidieri, Sauss. I am indebted to Mr Rowland 

 E. Turner of the British Museum of Natural History for the 

 identification of this species. He states that the specimens under 

 review are of "a form of D. grandidieri, Sauss. from Madagascar, 

 with a few more punctures on the abdomen than in that 

 species." 



Ampulex compressa, Fab., not previously recorded from 

 Rodrigues. Common from Eastern Europe to China, and also in 

 Africa. 



Passaloecus (Polemistus) macilentus, Sauss. Mr R. E. Turner has 

 kindly identified this species for me. He states (in litt.) that "Mr 

 Morice considers that Philoctetes coriaceus, Dahlb. is probably 

 parasitic on this, as species of Passaloecus are often attacked by 

 small Chrysids." The species was described from Madagascar. 



Sceliphron hengalense, Dahlb. ( = Peolpaeus convexus, Sm.). 

 Mr Turner has confirmed my identification of this species. He 

 adds: "This is probably an imported species, as species of the 

 genus build mud nests on ships and are carried in that way from 

 place to place." 



Trypoxylon errans, Sauss. Not previously recorded from 

 Rodrigues. Found also in Mauritius and the Seychelles. 



There are approximately 750 specimens of Coleoptera, of pos- 

 sibly 100 species; 640 specimens of Diptera, of at least seventy 

 species; and 360 specimens of Hemiptera, of some forty-five 

 species. These have not yet been critically examined. 



In the Lepidoptera, seven species of Butterflies were collected 

 by Mr Grulliver on the Transit of Venus Expedition. Of these one 

 species is not represented in Mr Snell's collection, viz. Hesperia 

 forestan, Cr. The list of Butterflies is as follows : 



'^Melanitis leda, Linn. '\*Zizera lysimon, Hiibn, 



*Danais chrysippus, Linn. "f^Polyommatus boeticus, Linn. 



Precis rhadama, Boisd. *Tarucus telicanus, Lang. 



*Hypolimnas misippus, Linn. Parnara borbonica, Boisd. 

 "f^Atella phalantha, Drury 



Among the Moths (Heterocera), exclusive of the Pyralidae, 

 Tortricidae, and Tineidae, though Gulliver's collection contained 

 only twelve species, five of these were species not represented in 

 Mr Snell's collection, Mr Snell obtained three species of Sphingidae, 



* Of wide distribution.
