LIMNOPIIILA. 207 



Front and vertex brownish, with a gray bloom ; rostrum and 

 palpi brown ; antenna? brownish, basal joints yellowish ; those 

 of the male are much longer than the thorax ; first joint rather 

 short ; joints of the flagellum elongated, subcylindrical, densely 

 pubescent, and with a few verticils about the middle ; thorax 

 brownish above, with a yellowish-gray bloom ; pleurae yellowish ; 

 halteres with a brown knob ; abdomen reddish-yellow, posterior 

 margins of the segments brown ; last segment brownish ; forceps 

 yellow. "Wings almost hyaline, banded and spotted with brown 

 as follows : the inner end of the basal cells, the costal and sub- 

 costal cells, three large spots at the origin of the praefurca, on the 

 supernumerary cross-vein of the second basal cell, and at the tip 

 of the seventh vein ; these spots are almost, but not quite in con- 

 tact, and thus form an interrupted band ; the first spot is connected 

 with the brown of the anterior margin ; the brown stigma and a 

 series of spots along the central cross-veins form a second cross- 

 band ; the apex of the wing is infuscated, and there are clouds 

 at the inner ends of the three intermediate posterior cells. 

 Marginal cross-vein near the tip of the first vein ; praafurca with 

 a stump of a vein near its origin ; the inner ends of the second 

 submarginal, first posterior, and the discal cells nearly in a line. 



JIab. Massachusetts (Mr. Scudder) ; a single male. 



My only specimen is somewhat injured, the feet and the tips of 

 the antenna? being broken. This species is very like the European 

 Limnophila (Idioptera) pulchella Meig. (syn. L.fasciata Schum. 

 non Linn, according to Dr. Schiner). It may be that they are 

 the same species, and it is upon this assumption that I introduced 

 the American species as L. fasciata Schum., in my former paper. 

 The European species has generally abortive wings in the female 

 sex (compare Schum. Beitr. etc. Tab. Y, fig. 2). L. fasciolata 

 is closely allied to L. poetica, and it would be unnatural to sepa- 

 rate them on account of the presence of the supernumerary cross- 

 vein of the former. (About Idioptera compare p. 199.) 



4. Lr. poetica, n. sp. % . — Ferrugineo-flava, antennis fuscis, articulis 

 basalibus flavis ; in mare thorace plus quam duplo longioribus, articulis 

 elongatis, pubescentibus ; alse immacnlatse, stigmate pallide infuscato, 

 praefurcse basi appendicular. 



Reddish-yellow, antennae brown, basal joints yellow ; in the male the an- 

 tennae are more than twice the length of the thorax ; joints elongated,
