Head and thoi'ax pale yellowish brown. Antennae yellowish brown, 

 strono'ly bipectinate. Fore coxa3 red inwardly. Legs clay colored, 

 marked with brown, the femora stained with red within. 



Expajtse, 60 mil. One fresh male (869), 



Larger and less yellow than Edwardsii, differing by the bi'own- 

 ish thorax. The terminal abdominal marks when present in 

 Edwardsii are more or less diffuse and livid. 



Quadrina. n. gen. 



Tlie primaries are short and wide. The cell is very short and 

 veins long. Median vein 4-branched, cell open, veins nearly equi- 

 distant vein, 4: from base of cell. Yein 10 out of 9, a long furca- 

 tion. Abdomen untufted. Differs from CitJieronia by the de- 

 pressed apices, long, curved nervules and 4-branched median vein 

 ■of primaries. Veins 6 and 7 thrown off together; 8 ansing mid- 

 way between 7 and 9. Median vein on hind wrings also -i-branched ; 

 ■cell open, nervules straight and long ; 4 and 5 together ; 3 near 4 

 from lower side of vein. Costal and subcostal veins forming an 

 accessory cell at base. Head rather broad and not as sunken as 

 usual ; thorax hardly elevated in front, Squamation and aspect of 

 CitJieronia sepidcralis. The cell on primaries appears closed at 

 base by the fusion of subcostal and median veins, 



Quadrina Diazoma. n. s. 



? . Antennse pectinate to tips, brownish. The four wings 

 nearly concolorous brownish, brighter at base, where they have longer 

 scales. A curved, even, dark, extra mesial shade line on primaries. 

 An uneven, broken, subterminal line. Hind wings with a reddish 

 «hade, which obtains slightly at apices of primaries. Body darker, 

 •concolorous. 



Expanse^ 95 mil. 



The neuration of this speciel seems to me to be indicative of 

 a comparatively low and old type of Bombycidae. This is seen 

 in the long veinlets, equidistant ; the shape of the wing, the costal 

 margin curved, depressed before apices. Without the male, it is 

 difficult to be certain of the true position of this form. The brown 

 ■color is brighter, more red tinted, brighter ochery brown at base of 

 wings than in Coloradia Pandora^ and altogether it is removed 

 from that type and in several characters approaches Citheronia. 

 Differs from Gloveria, by the larger head, broader clypeus and 

 •smoother body clothing. There is a gray mixture on the fore wings 

 of Coloradia and Gloveria, wanting in Quadrina, which is a smaller 

 insect. The pectinate ? antennae separate the moth from the 

 Ceratocampidoe. The shape of the wings is like Eacles, but on the 

 whole the outline is more like HypercJiiria. While structurally 

 remote from any described U. S. genus, it may be catalogued next 

 to Gloveria for the present. 



Rhododipsa Miniana. n.s. 



Eyes naked. Thorax covered with narrow scales. Front full. 

 Thorax lighter honey-yellow or orange ; this color spreads over base
