A New Genus and Species of T<ii/i/<lcri<l<tf'. 



angle moderately prominent. Male hypopygium with the pleurites 

 very slender, greatly elongated, gradually narrowed to the tips, each 

 bearing a single very elongate, cylindrical appendage that is provided 

 with a series of about 30 slender spines and numerous erect setae 

 along its inner margin, at the apex with two elongate bristles. 



Genotype, Peringueyomyina banmrdi, sp. n. (Southern Ethiopian 

 region). 



This new group is easily separated from the related genera of the 

 Tanyderidae by the elongate rostrum and by the structure of the 

 antennae and male hypopygium. The genus Macrochile, Loew (fossil 

 in Baltic amber), has the rostrum longer than the head, but the large 

 and conspicuous palpi arise from near the middle of its length. 



I take great pleasure in dedicating this remarkable genus to 

 Dr. L. A. Pcringuey. 



PERINGUEYOMYINA BABNARDI, sp. n. 



Rostrum and antennae black ; mesoiiotum brownish-yellow, the 

 praescutal stripes indistinct ; wings yellowish, the stigma small, pale 

 brown ; abdomen ringed with brown and yellow. 



Male. Length (excluding rostrum and geuitalia) 8'6 mm. ; rostrum 

 alone 37 mm. ; geuitalia, pleurite 2 mm. ; appendage 2 mm. ; wing 

 10 mm. ; greatest width 3 mm. ; antenna about 2 - 3 mm. 



Peringueyomyina barnardi, sp. n. 



r?f Rostrum, including the mouth. -parts, dark brownish-black. Antennae 

 black ; in the type only 14 segments are present, but the extreme 

 apex is broken, and the complete organ presumably has either 15 or 16 

 segments. Head dark. 



Pronotum brownish-yellow, passing to almost black on the inid- 

 dorsal region. Mesonotum shiny brownish, with three indistinct 

 darker shiny stripes on the praescutum, the scutal lobes brownish.
