NOTES ON SOME SPECIES OF NOTODONTIDffi IN THE 



COLLECTION OF THE UNITED STATES NATIONAL 



MUSEUM, WITH DESCRIPTIONS OF NEW 



GENERA AND SPECIES. 



By Harrison G. Dyar. 



Family NOTODONTID^. 



Malocampa puella, n. sp. 



Thorax dark brown on the disk, the patagia silvery gray, tegulse and 

 vertex cinereous. Abdomen brown dorsally, pale beneath, the last 

 segment silvery gray. Fore wings yellowish silvery-gray, a brown 

 spot on costa at basal third, obsoletely connected to a large triangular 

 patch on the middle of inner margin ; a small costal patch at outer 

 third, followed by three costal dots ; a terminal row of brown spots 

 in the fringe. Hind wings brown, irregularly yellowish towards the 

 base. Beneath washed with brown, the hind wings yellowish except 

 at the margins. Expanse 45 mm. 



One male and 3 females, Area, Venezuela, and Orizaba, 

 Mexico (collection of Wm. Schaus). 



Type. — No. 11319, U. S. National Museum. 



I have separated this species from the series of Malocampa 

 bolivari Schaus in the Schaus collection. The types of holivari 

 consisted of a male and female, but in reality both are females, 

 one with pectinated antennae, the other with simple antennae. 

 I have restricted bolivari to the male type (really a female) 

 and describe the species with simple antennae in the female as 

 piiella. 



Congruia congrua, n. gen. and sp. 



Vein 5 of secondaries obsolete ; accessory cell present on fore wings, 

 small, vein 6 arising from its middle, 7 to 10 stalked, 10 arising near 

 base of stalk; antennse of male fasciculate on basal half; vein 8 of 

 hind wings diverging from cell at middle, palpi upturned, exceeding 

 the vertex, the second joint thickened with scales, the third long, slender, 

 nude. Wings long and narrow. Thorax brown, with ocherous inter- 

 mixture on patagia, a high backwardly-directed tuft on collar blackish- 

 tipped behind; abdomen brown above, pale ochraceous below, a double 

 brown dorsal line on the last two segments. Fore wing longitudinally 

 lined; a heavy brown shade along median vein from base straight 

 along vein 4 to margin; another line along vein 6 running to costa 

 at base of this vein, the space between veins 4 and 6 beyond cell nearly 

 continuously brown shaded; a similar shade along internal margin; 

 faint tracings of fine lines on the outer third of wing, most distinct on 

 costa; a waved, broken double line at the base of the fringe; a round
