shorter; IX very short, indistinct, comprising only a short apical 

 portion of VIII-IX. Fore^dngs small, whitish, ^vrinkled, covered 

 with numerous small round, brown spots, as in artemisise. In both 

 forewings of all three specimens at hand (both sexes) there is a 

 remarkable anomalous venational character; Cu^ and M^ unite and 

 send a common vein to the margin, thus making a supernumerary 

 cell. The uniformity of these veins in both forewings of several 

 specimens is a remarkable anomaly. Additional material is necessary, 

 however, to ascertain the general prevalence of this character. 



Male genitaUa somewhat similar in general type to those of arte- 

 misise; forceps with a small inner subapical tooth, not serrate on 

 apical margin, as in minutissima. Female genitaha, as in artemisise. 



Described from two females from Sacramento, California (Koebele), 

 June 28, 1885, and one from Folsom, California (Koebele). No other 

 specimens from either of these locahties are available. These bear 

 the manuscript name of A. occidentalis anomala Riley. A. occiden- 

 talis was a manuscript name for ininutissima.

APHALAROIDA, new genus. 



Head resembling somewhat that of Ajphalara, but shorter, slightly 

 less flattened, somewhat rounded down in front, but much less so 

 than in HeteropsyUa; gense somewhat swollen beneath, never conical, 

 not covering frons; frons similar to Aphalara, but much shorter. 

 Antennse very short. Thorax only slightly arched; pronotum ter- 

 minating laterad in a knob-like swelhng, with the pleural suture extend- 

 ing to the midpoint of this as in Ajphalara. Wings small, thickened, 

 opaque, or semiopaque, often maculated, with a pterostigma. Anal 

 valve of male simple, not as in Aphalara. Body surface often covered 

 with glandular hairs. 



Type of genus. — ApTialaroida piihecolobia, new species. 



This is a very homogeneous and interesting httle group of species, 

 distributed over southwestern and southern United States. There 

 is a remarkable similarity throughout the genus in structural char- 

 acters, the species differing chiefly in size, amount of glandular 

 pubescence and in markings of body and wings. There is some data 

 to show that summer and winter forms of the same species differ in 

 color and markings to some extent. The species are so similar that 

 only a brief description of aU but the type is given herewith.
