claws fully twice as long as last tarsal joint, others nearly twice as 

 long as same. Wings longer and narrower, the origin of apical cross- 

 vein conspicuously nearer hind margin of wing than length of hind 

 cross vein. 



The name is from the Algonkin word "makasin," commonly spelled 

 moccasin in English. Notwithstandmg that the above differences 

 seem slight and evasive so far as puttmg them in words may go, this 

 form can not possibly be referred to Archytas even as a subgenus.

 Eulaha, Peru, about 3,500 feet, on foUage, April 28, 1914 (Townsend).

 flavous anteriorly, rufotestaceous posteriorly. Parafrontals black, 

 thinly silvery. Whole face and cheeks silvery-white. Occiput 

 brassy-silvery, beard pale yellow. Thorax shining black, thinly 

 dusted with brassy-silvery, more thickly brassy anteriorly and on 

 pleurae. Scutellum dark shining testaceous. Abdomen dark shining 

 rufotestaceous, a faint blackish median vitta showing. Legs blackish,

ANEMORILLA, new genus. 



Genotype. — Anemorilla rufescens, new species. 



Differs from Nemorilla as follows: Female only described. Dis- 

 tinct facies. Hind tibiae without sign of cihation or approach to it. 

 Vibrissae inserted at point well removed from oral margin. Third 

 antennal joint broad, only one and one-half times as long as the 

 second; second joint very elongate. Frontals descending low, below 

 base of third antennal joint. Apical cell ending a very httle before 

 wingtip. Head rather broad and shortened, parafacials narrow. 

 Discal bristles on intermediate abdominal segments. Ovipositor 

 fleshy, telescoped. Deposits an elongate-elHptical flattened white 

 macrotype egg, and evidently belongs to the Exoristinae.
