and yellowish hyaline wings. The other, Lonchaea aurea, in spite of its short 

 description, is at once recognisable as the widely spread Lonchaea splendida, Loew. 

 The third species of the family was described from West Africa, Assinia, by Bigot 

 under the name of Palloptera pantherina (Bull. Soc. Ent., France, Ix, 1891, p. 382) ; but 

 as the genus Palloptera is exclusively palearctic and nearctic the species was wrongly 

 assigned to it. Bigot was himself in doubt about its systematic position ; and 

 the insect is actually an Ortalid, recognisable by its peculiar body and wing-pattern, 

 and now known as Simomesia pantherina, Big. 



More recently Mr. C. G. Lamb, in dealing with the rich material collected by the 

 Percy Sladen Trust Expedition to the Indian Ocean in 1905, under the leadership 

 of Prof. J. Stanley Gardiner, has notably increased our knowledge of the genus 

 LoncJiaea. In his work, published in 1912, there are four species. The first is the 

 well known L. splendida, which however must be called aurea, Macq. The second 

 is described as new under the name of L. plumata, but is evidently the same as the 

 Oriental L. excisa, Kertesz (1901). The third is described under the name of 

 L. longicomis ; but as there is already another species of the same name described 

 from the West Indies by Prof. Williston (Trans. Ent. Soc. Lond., 1896, d. 378), and 

 recorded also from Porto Rico by Coquillett, a new name is necessary for it. The 

 fourth is described as L. vibrissifer. 



Finally, I have myself in a note in my second paper on the Ceratitis bred in Africa 

 by Prof. Silvestri (Boll. Lab. Zool. Portici, vii, 1913, p. 21) recorded a species from 

 West Africa under the name of L. glaberrima, Wied. 



I have now before me five Ethiopian species of Lonchaea, two of which are to be 

 described here as new ; and adding those recorded by other authors, I propose the 

 following table of distinction : — 



1(2). 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 ; antennae very short, widely separated 

 at base, with bare arista ; cheeks and jowls broad ; only one strong 

 sternopleural macrochaeta present . . . . . . . . mochii, sp. n. 



2(1). Eyes bare ; head not or only a little broader than the thorax, with less widened 

 frons in the female and with well developed macrochaetae ; lunula small, 

 usually less visible and less or not hairy ; antennae usually longer and 

 closer together at base ; cheeks and jowls narrow. 

 3(10). Arista bare or only microscopically pubescent ; (all the species here 

 distinguished have moreover the tarsi with yellow base and the squamulae 

 white and with pale cilia). 

 4(7). Antennae short, extending only a little below the middle of the face ; jowls 



rather broad. 

 5(6). Vibrissae not longer than usual ; wings yellowish hyaline . . claripennis, Macq. 

 6(5). Vibrissae very long ; wings brownish . . . . . . vibrissifer, Lamb. 



7(4). Antennae long, extending much below the middle of the face ; jowls narrow. 

 8(9). Entire body, except head, of a very glistening green, more or less golden ; 

 third antennal joint not reaching the mouth-border ; only one sternopleural 

 macrochaeta . . . . . . . . . . . . aurea, Macq.
