FUETHER NOTES ON THE LONCHAEIDAE (DIPT.), WITH DESCRIPTION 

 OF NEW SPECIES FROM AFRICA AND ASIA. 

 By Prof. M. Bezzi, 

 Turin, Italy. 



Having received from the Imperial Bureau of Entomology more material of the 

 family Lonchaeidae, I am in a position to give the following additional notes to 

 my previous paper* on the Ethiopian species. 



I think moreover it will be useful to offer a view of the Asiatic and Australian 

 species at present known, as it seems that some of these flies (chiefly those of economic 

 importance) are widely spread over the tropical countries of the Old World. Thus 

 I have now found that the African plumosissima lives also in the Philippine Islands ; 

 and that the Oriental citricola is to be found also in Australia. The wide range of 

 aurea (splendida) is already known. 



The Subgenera of the Genus Lonchaea, s.l. 

 In my previous paper (pp. 253-254) I have already shown that the genus 

 Lonchaea may be divided into three natural groups, which are weU characterised 

 structurally and ethologically. These groups may be considered at present as 

 subgenera, but further studies will probably show their generic rank. 



For the first group (type chorea, Fabr. ) and the second group (type lasiophthalma, 

 Macq.) there are already the names Lonchaea, s. str., and Dasyops, Rond. I will 

 propose here the name Carpolonchaea, subgen. no v., for the mainly tropical species 

 of the third group with feathered arista and with two sternopleural bristles (type 

 plumossissima, Bezzi). The proposed name indicates the carpophilous habits of 

 these species. 



A new subgenus is probably to be erected for the reception of the somewhat 

 aberrant Lonchaea aurea {splendida), which has a rather isolated position in the 

 genus Lonchaea, s. str., on account of the different form of the head, the peculiar 

 venation of the wings, the metallic colour of the body and the habits of the larva. 

 The name Lamprolonchaea, subgen. nov., (type aurea = splendida) is proposed 

 here for it. 



The Ethiopian Species. 

 In my previous paper 8 Ethiopian species of the genus Lonchaea were distinguished ; 

 as I have now received 5 other species, thus bringing the total number to 13, the 

 following new table of distinctions is necessary : — 

 1(4). Antennae very short, widely separated at base, inserted a little below the 

 middle of the eyes, with bare arista ; eyes hairy ; head considerably 

 broader than the thorax, with a very broad frons in the female, and with 

 short and thin macrochaetae ; lunula very broad, open and roughly hairy ; 

 cheeks and jowls broad ; sternopleurae with a single strong macrochaeta ; 

 mesopleurae with anterior macrochaetae not developed ; wings shorter 

 than the body, with the second costal cell not dilated outwardly, and with 

 the sixth longitudinal vein destitute of spurious continuation (subgen. 

 Dasyops, Rond.).
