Three females from the vicinity of Los Angeles were sent to 

 me by Mr. Coquillett for examination and study. 



DiCTYOBiA. New genus. 



Form similar to Neaethus, having the wing-covers sloping, 

 broad, and subangulately expanded before the middle, ramosely 

 reticulate, with the areoles large and irregular. Head nar- 

 rower than the pronotum, the vertex carinated in front and on 

 the sides, posterior margin broadly sinuated, front quad- 

 rangular, carinate on the middle line and superior and lateral 

 margins, sinuated below, almost truncated above. Pronotum 

 short, lunate, somewhat sunken, with the margins a little 

 reflexed. Scutellum hardly as wide as the pronotum, obsoletely 

 carinate on the middle, and with an ovate callosity next each 

 basal angle. Legs stout, with the tibiae keeled and spined as 

 in the preceding genus, the posterior tarsi flattened, and with a 

 spine at the outer angle of the two basal joints. Wing-covers 

 more broadly margined all around than in Dictydea, with the 

 cells of the apex, exteriorly, much longer than the rest, basal 

 area of the clavus crossed by a single veinlet, the principal area 

 crossed by five veinlets, of which the three apical ones form a 

 group by themselves. Abdomen stout, subconical, almost car- 

 inate above, compressed at the posterior end. 



D. permutata. New sp. 



Obmitrate,* fuscous, or fusco-piceous, marked with testa- 

 ceous. Head broad, truncated, moderately polished, with the 

 carinate lines and space beneath the eyes more or less pale ; 

 eyes brown ; antennae piceous, having the border of the socket 

 well raised, the basal joint almost spherically enlarged at tip, 

 the second joint very short and narrow, and the apex consisting 

 of a long, slender bristle; vertex sunken, having the middle 

 line, lateral and posterior margins testaceous. Pronotum with 

 the anterior margin testaceous, slenderly recurved, the middle 

 line also testaceous, percurrent with the line on the head, and 

 also with that on the scutellum, the surface each side of middle 

 indented. Scutellum with a dark brown callosity on each basal 



* This term is here used for a figure in the form of a mitre, in the reversed 

 direction.
