tarsi dear light \clio\v, s^ mctimcs infuscatccl at the lips; tibia' 

 often with a sub-basal aiinulus. In the \ial were scwral specimens 

 of E. asymmelrica, a clcseh- allied form, and most of the legs e\i- 

 dentl\- belong to that si^ccies. Two legs in the vial are \er>' dif- 

 ferent and ma\- belong to this little species, this being rendered 

 l>r( bailie b\- the size; in these the entire legs are clear, light \ellow, 

 the feiiKM-a with a rather nam w snliiipical dark brt wn ring). 



Wings spi:tted with brown. 



Abdomen: Tergum dull brownish \ellow, apex and laterai 

 margins cf the sclerites bn wn. H\]3<,|iygium unsymmetrical as in 

 the genus, the 9th abch minal segment being twisted one-half 

 around. Suture between the !)th Icrgitc and the Olh sternite not 

 indicated. The 9tii tergile is bnad and long, its hind margin pnj- 

 duced caudad in a wide, thin plate which is broadh- and rather 

 dcepK- notched at its middle: no chitinized heoks at its apex. The 

 i:)leuriics are ccn\ex i ulerly (produced into two apical appendages), 

 the base (dorsal) pnduced entad and cephalad in a long, chitinized 

 h(ck; the ventral edge c f the jileura near the sternum possesses a 

 small chitinized organ w iiich is directed caudad and is pro\ided 

 with two or three deniiiuia': c f the two a[>ical appendages, the 

 Aentral one is chitinized, the d(,rsal i.ne is fleshy, the second gona- 

 pophyses are clcsj; together, the chitinized tips rather long and 

 deeply divided. (See plate X, figs. 5 and 6).

 Erioplera {Acy phono) asymmetrica, sp. n. 



Resembles incongriiens closely, but is larger, the coloration 

 darker, especially on the pleura' and usually on the abdomen. 

 Wings hyaline, spotted with brown, varying considerably in the 

 intensity and size of the markings; in some the dots arc small, not 

 ccnfiuent, in the darker specimens the spots on the costal half of 

 the wing tend to flow together to form large blotches. The male 

 genita'ia of the two species is remarkably dilTerent. (See plate III, 

 fig. 1.5. wing.) 



The hyjKipygium is, as in the genus, asymmetrical, the usual 

 dorsal portions of the 9th sclerites being switched around on a level 

 with the pleural sutures of the remaining segments. (See fig. 7-9, 

 plate X), suture between 9th tcrgite and sternite obliterated, 9th
