INSECUTOR INSCITI^ MENSTRUUS 87 



and runs thence to the inner margin, faintly shown above across 

 the discal nervules, crossing 3 and 4 and running into the inter- 

 space 4—5. Hind wing whitish on inner half, pale fuscous on 

 costal half. Expanse, 19 mm. 



Type, male, No. 21140, U. S. Nat. Mus. ; East River, Con- 

 necticut, August, 1907 (C. R. Ely). 



This species is peculiar in frequently having vein 10 stalked 

 with 8 and 9. The stalking occurs by a fusion of 10 with the 

 stalk beyond the base, so that a small triangular accessory cell 

 is left. This occurs in five out of seven specimens before me. 

 The other two have vein 10 free, although bent toward the 

 stalk. The tongue is practically absent in the male, but quite 

 distinct in the female. 



Two other species of Platytes with dark-lined veins are 

 known, multilineatella Hulst and punctilineella Barnes & Mc- 

 Dunnough, both from Florida. They are both narrower- 

 winged than panalope, darker and more uniform. In all these 

 species, the hind wings of the female are white or, at least, 

 paler than those of the male. Therefore I think that Hulst 

 described multilineatella from two females instead of two 

 males, as stated, since he describes the hind wings as pure 

 white. 



Haimbachia venosalis, new species. 



Fore wing white, the veins broadly lined with chocolate 

 brown, the interspaces with narrow lines of the same color, 

 ending in small terminal black dots; a distinct black discal 

 spot ; fringe interlined. Hind wing white, the veins lined in 

 brown at apex. Expanse, 17 mm. 



Type, male, No. 21141, U. S. Nat. Mus.; Audubon Park, 

 Louisiana, September 19, 1914 (U. C. Loftin), at light. 



The female is the same, only a little larger, expanse, 21 mm. 

 The tongue is absent in the male, but distinct in the female, 

 which throws the species out of Diatrcea. It resembles Platytes 

 multilineatella Hulst in a general way, but veins 11 and 12 of 

 fore wing anastomose, compelling the reference to Haimbachia.
