Tabanus sulumenais, cT ? , sp. n. 



Tvpc (female) and type (nnile) from Solomon Islands, 

 Julv-Anj;n>t, IDOl) (//'.'//'. I'rof/t/a/i) . 



These .spicimens from Mr. Fro;:j;atl'.s Coll. are placed by 

 Itim under Tahaniis aniens, W'icd., which was described from 

 Java. lie states this s{)eeies is very common in tlie open 

 forest-country of the Solomon Islands, and sujjfjcsts it has a 

 wide ran«j;eovcr the Malay Archi|)ela;^o (see " ^larch Flies," 

 by W. \\ . Frojr<;att. in Science iiuih^tin, No. 3, Sept. 1911, 

 p. G). ^Viedemann's species is not known to me, but 1 do 

 not think these are specimens of it, judginj; from AViedc- 

 niann's description (see translation of the orij^inal in ' Indian 

 Kecords,' iv. no. vi. p. 224', 1911). The thorax in these is 

 not mouldy grey, the jialpi are not light brown, nor are tlie 

 breast-sides mouldy grey. On the abd(nnen there is no trace 

 of a j:olden-ycllow spot, and it cannot be described as waxy 

 yellow at si(les ; the golden-yellow i)ubescencc on it is not 

 mentioned by ^Viedenlann. \Vings are not yellowish, but 

 brownish, llalteres are black, not golden yellow. 



No species of Tabanus has been described from these 

 islands, and these specimens do not appear to be identical 

 with any species hitherto described from New Guinea or 

 adjacent islands — hence the decision to make it a new 

 species. 



A species to be recognized by the uniform oehraceous 

 tawny colouring of thorax and abdomen, and the almost 

 similar colouring of the antennje, palpi, and legs. The 

 extremely narrow forehead and frontal callus is character- 

 istic, also the slender antennrc. 



Length, ? 13 mm., (^ 12 mm. 



?. /''«ce and /o;Y7/e«^/ oehraceous tawny. Beard scanty, 

 reddish yellow. Palpi a sliade lighter in colouring, almost 

 the same width throughout, ending in a short point, with 

 a few black hairs at tip, otherwise pubescence is yellow. 

 AntetiiHC long and slender, tlie first two joints the same 

 colour as palpi, the tliinl dusky, the first division not very 

 broad, with a very small tooth, the last four divisions to- 

 gether longer than the first one. Forehead parallel, very 

 narrow, about ten times as long as it is broad ; the frontal 

 callus small and narrow, with a stout lineal extension, 

 chestnut-brown in colour. Thorax has the ground-colour
