490 NORTH AMERICAN NOCTUIDzE — SMITH. 



with dark center ; reniform constricted at the center, white margined 

 with a dark filling. Subterminal space shaded light. Beneath of a 

 lighter shade, discal spot and a faint trace of the t. p. line. Second- 

 aries shining fuscous, fringes whitish, beneath lighter, discal spot 

 black, very evident. Expanse 20 mm . Texas. (O. Meske.)" 



" This species is allied to trifolii. The antennae are pectinate, while 

 in trifolii they are simple. In orobia the darker costal edge shows the 

 white dots distinctly." 



This is not now in the Meske collection. Mr. Grote referred it in 

 1881 to Tccniocampa, Harvey having described it as a Mamestra. The 

 pectinated antennas would seem to ally the species either to rufula or 

 to incincta, according to the wing form, which is not described. 



PERIGRAPHA Led. 



Noct. Eur., 1857, 136. 



A free translation of Lederer's description of the genus Perigrapha 

 is as follows: "In habitus and the hairy eyes these insects resemble 

 Tceniocampa ; but the collar is excavated at the sides and joined at the 

 middle in a sharp edge ; the thorax is somewhat produced at the sides, 

 and behind the collar there is a distinct crest. On the basal segment 

 of abdomen there is a large truncate tuft of hair. Antennas in both 

 sexes pectinated, in the female the pectinations shorter. Primaries 

 ash or brown gray, the usual spots unusually large, confluent, some- 

 what paler than ground color, deep black margined." 



Except in one particular our species agree perfectly with the essen- 

 tial portions of this diagnosis, i. e., in none of the species known to me 

 are the antennas in the female pectinated, but serrated in some. The 

 character is an uuusual one, and an important one for that reason ; 

 but, as otherwise, the species are so close to the European forms they 

 had better be retained as congeneric — for the present, at least. 



The head is strongly retracted, the palpi scarcely reaching or hardly 

 exceeding the front. The body is robust, obtaining a somewhat clumsy 

 appearance from the thick, rather loose, vestiture. The abdomen, 

 compared with the large thorax, is small and short ; little or not 

 exceeding the hind angle of secondaries. In addition to the large 

 truncate basal tuft, the males are furnished with smaller lateral tufts. 

 The genitalia are various and separately described for each species. 

 The primaries are proportionately rather long and wide, the apices 

 acute, but slightly prolonged; outer margin obliquely rounded, leav- 

 ing the middle somewhat prominent. The wing shape will serve to at 

 once distinguish the genus. 



Two well-marked groups are recognizable in our species; the first, 

 and most typical, with the ordinary spots confluent. In this also the 

 thoracic vestiture has scales and capitate hairs intermixed. The second, 

 with the spots normal, separate and not unusually large. The thoracic
