DIPTEROUS FAMILY PAKTOPHTHALMID^, 577 



face as being " very broad and very greatly widened in front " ; 

 a comparison, however, of the British Museum specimen with 

 examples of other species shows that the $ of P. chuni is in no 

 way abnormal in this respect. Secondly, both in the diagnostic 

 table on p. 102 {loc. cit.) and in the detailed description on the 

 following page, Enderlein speaks of a single, relatively narrow 

 thoracic stripe. On the other hand, in actual fact, not only does 

 the dorsum of the thorax exhibit the three dark tlioracic stripes 

 so constantly seen in representatives of the family Pantoph- 

 thalmidaj, but, even regarding the thoracic markings as con- 

 sisting of a single stripe, bearing on its surface a pair of paler, 

 admedian stripes, the measurements given by Enderlein himself, 

 which agree in detail with the corresponding measurements taken 

 from the British Museum specimen, show that as a characterization 

 "relatively narrow" is entirely unwarranted. 



Pantophthalmus conspicabilis, sp. n. (Text-fig. 5.) 



2 • — Length (one specimen), including ovipositor and facial 

 beak, 42 mm. ; width of head 10'5 mm. ; width of front at vertex 

 1-8 mm. (immediately above base of antennae just under 2 mm.); 

 lengtli of facial beak just under 3 mm.; greatest width of 

 abdomen (across third tergite) just under 16 mm. ; length of wing 

 31'5 mm. 



In 5 sex, at least as represented hy typical specimen, a grey and 

 black species, loith prominent, sharp-pointed facial beak ; almost 

 parallel-sided front; conspicuously striped thorax; blunt-edged 

 abdomen, which on dorsal surface, on each lateral border, hears ttoo 

 co7ispicuo'us silvery-white spots and a fringe of short hair ; icings 

 marbled ivith sejna and light hihff, somewhat resembling those of 

 Pantophthalmus (Acanthomera) chuni Enderl., Imt differing in 

 details of pattern ; and with hind femora incrassate toioards tips, 

 and bearing a small spine on under surface and a large terminal 

 spine. 



Head: face and jowls sepia-coloured or mummy-brown, inner 

 margin of each eye bounding face with a narrow, smoke-grey, 

 pollinose edging, which above sends ofTan extension to meet base 

 of facial beak, while below a similar but silvery-grey extension 

 connects pollinose edging of eye with buccal cavity ; facial beak 

 long and sharp-pointed, its expanded basal portion dark brown 

 above, russet-brown on sides below, the shining tip blackish- 

 brown ; front (frons) of moderate width, and only very slightly 

 broader at its anterior extremity than at vertex ; front and 

 occiput, including posterior orbits, uniformly olive-bufF or pale 

 olive-buff pollinose, except that the conspicuous ocellar tubercle, 

 Avhich is distinctly separated from vertical margin of occiput, 

 is mummy-brown, and that in certain aspects, at least in 

 t^'pical specimen, behind ocellar tubercle, on vertical margin 

 of occiput, and also on central anterior portion of front, 

 above base of antennoB, ground-colour shows through pollinose
