DESCRIPTIONS OF CERTAIN NEW FORMS OF LEPIDOPTERA. 



BY B. NEUMOEGEN AND HARRISON G. DYAR. 



Family Lagoid^. 

 Vein ia of primaries present ; median, 4-branched ; vein 8 of second- 

 aries arising from the subcostal, more than half the length of cell from 

 base ; <$ antennae pectinated to the tip. 

 Synopsis of genera : — 



Antennae long ; body parts robust. 



Veins 3 and 4 of secondaries stalked Carama. 



Veins 3 and 4 separate, arising from the median Lagoa. 



Antennae very short ; body more slender Dalcerides. 



Genus Dalcerides, ;/. gen. 



Head very small, but with large eyes ; palpi slender, antennae very 

 short, hardly as long as the thorax, finely bipectinated. Vein 1 of 

 primaries free, unbranched ; 1 a present; median vein 4-branched, vein 2 

 arising beyond the middle, veins 3-5 from near together ; cell broad, 

 closed, with false discal vein ; 6 from the middle of the retracted upper 

 half of the cross vein, a small rounded accessory cell ; 7-8 on a stalk 

 from the pointed end of the accessory cell; 9 from the same point ; 10 

 apparently absent; n from top of accessory cell, appearing to join 12, 

 which is free from base. The secondaries have two internal veins ; veins 

 2-6 as on primaries ; 7 a continuation of the subcostal; 8 from subcostal 

 on middle of cell, not diverging till end of cell ; a discal false vein runs 

 to the angulation of the cross vein between the origins of veins 5 and 6. 



Type, Artaxa ingenita, Hy. Edw. 



Family NotodontiojE. 



Median vein of primaries 3-branched ; 8 of secondaries from base, 

 close to subcostal for a large part of its length ; veins 3 and 4 not stalked. 

 Partial synopsis of genera : — 



Outer margin of primaries entire. 



$ Antennae pectinated to the tip, the pectinations as long or longer 

 than their cilia. 

 Primaries without accessory cell. 

 Internal margin entire. 



Vein 5 of secondaries weak or absent. 



Tip of abdomen with a brusrwlike tuft. ..Melalopha.
