ZOOLOGY OF FERIS^ANDO NOEONHA. 543 



with tawny, and with more mimeroixs punctures than in 

 -ff. IcBvipyga ; the punctures o£ the mesothorax and the lower 

 part of the metathorax larger; the channel of the metathorax 

 narrower ; antennre black above, ferruginous below ; cheeks 

 bronzed. 



Closely allied to H. Irevipygn, but diifers " in colour and 

 punctuation. Appears to be a very common species. 



32. Haltctus ateipyga, u. sp. 

 S $ . Long. corp. 5 millim. 



Head and thorax clothed with whitish hairs, green, very finely 

 punctured ; head much bronzed ; clypeus rather short, the tip 

 black; metanotum longitudinally striated in front; abdomen 

 bronzy black, more violet in the incisions ; antennae black, ferru- 

 ginous beneath ; head and thorax dull bronzy green beneath ; 

 abdomen beneath shading more into ferruginous brown ; wings 

 hyaline, with brown nervures ; tegulae pitchy ; legs ferruginous, 

 the femora, and sometimes more or less of the tibiae, blackish. 



A small species, not closely allied to any other, and easily 

 recognizable by the strong bronzy colouring of the back of the 

 head. 



These Halicti were taken in the flowers of the Melons and the 

 OxnUs, and play an important part in the fertilization of the 

 flowers in the island. 



33. Taeitcus Hanno, Stoll. 



PapiHo Hanno, Stoll, Suppl. Cram. pi. xxxix. ff. 2, 2 B (1790). 



Rusticus adolescens Hanno, Hubn. Samml. ex. Schmett. i. 



Many specimens, taken between July 25 and August 31. 



The Brazilian form of this widely distributed and variable 

 species. It is generally larger than the more northern form of 

 the species, and stands in the British-Museum collection under 

 the MS. name of T. monops, Zell. The specimens expand from 

 17^ to 23 millim. 



This little Blue was very common on Eat and Main islands. 

 The CafacJiri/sops trifracta, Butl., said to have been caught on 

 Eat Island by the ' Challenger ' Expedition, we did not meet with ; 

 and it seems possible that there was some mistake in the labelling 

 of this specimen, as the genus is only known from the East 

 Indies.
