184 GROTE & ROBINSON. 



wide, somewhat flattened ; anal tuft short, broad and squarely cut. Both 

 wings closely scaled. Primaries very narrow at base, suddenly swelled 

 terminally. Secondaries (in the unexpanded specimen) folded upon 

 themselves and covered by the narrow primaries to which they are 

 closely applied. Legs as in Aegeriaj hind tibiae with two pair of fine 

 and rather long spurs. 



This genus differs from Aegeria in the proportionally smaller head 

 and heavier thorax, the linear heavily ciliated antennse and flattened 

 abdomen, while the closely scaled secondaries present a character 

 seemingly unique in the Aegeriidae. 



Zenodoxus maculipes, n. s. 



Bronze color or silky brown. Palpi beneath pale, silky. Prothorax 

 with a narrow ring of obscure yellowish raised scales. Thorax aene- 

 ous brown, with sparse yellowish or ochreous scales before the insertion 

 of the wings laterally. Abdomen aeneous brown, the segments above 

 reflecting a paler, somewhat ochreous hue in certain lights owing to an 

 admixture of pale scales. Legs concolorous with the body, shaded 

 with pale scales. The hind tibiae are interrupted with pale yellow 

 between the spurs; this character is more obvious beneath, and it is in 

 allusion to it that the specific name is conferred. Wings, above, 

 shining reddish brown, concolorous and immaculate, with darker silky 

 fringes. The primaries appear longitudinally more thinly scaled, and 

 show a sprinkling of pale scales and a darker clouded mark on costa 

 at about the middle; all very inconspicuous, the wings presenting an 

 unicolorous appearance. The secondaries also show a dark dot at the 

 middle of costa. Costal edges pale ochreous, and the under surface 

 is paler than upper, and shows an admixture of pale scales.

Hahitat. — Texas. (Belfrage). 



Two specimens ofier no perceptible difference except that of size, 

 hence their sexual distinctiveness is not assured. The most prominent 

 character of the ornamentation of this uniformly dark species is the 

 pale yellow band on the hind tibiae between the tibial spurs. 



The species which, to our knowledge, most nearly resembles our 

 Texan insect is represented in our collection by two specimens labelled 

 " Sesia tineiformis," with the locality " Syracuse," (Sicily,) and as 

 coming from " P. C. Zeller." The tapering ciliated antennae and 

 scaled secondaries quickly distinguish our genus.
