DESCRIPTIONS OF NEW GENERA AND SPECIES OF THE 

 GEOMETRINA OF NORTH AMERICA. 



BY GEO. D. HULST, BROOKLYN, N. Y. 

 ( Coiiliiined from page i()5.) 



Selidosema nigrescens, n. sp 



Expands 31-33 mm. Palpi and front dark fuscous; antennae black 

 above, fuscous below \ thorax dark fuscous, patagise lighter ; abdomen 

 dark even fuscous. All wings dark fuscous, made by heavy coalescing 

 striations of fuscous and blackish on a light fuscous ground ; basal line 

 black, quite distinct, rounded, wavy ; a median shade passing through 

 distinct black discal spot ; an outer black distinct cross line, continued 

 across hind wing, on fore wing sinuous, subparallel with outer margin, 

 on hind wing nearly or (juite straight ; on fore wing beyond this line is a 

 broad reddish-brown band, not always clear, however, sometimes showing 

 faintly at middle of hind wing ; a submarginal row of light, not distinct, 

 lunules, edged within with darker ; marginal lines black, distinct. 

 Beneath fuscous, with faint line shadows, and a dark shadow spot near 

 apex of fore wings. 



San Antonio, Texas. The generic reference is provisional, as all the 

 specimens before me are females. 



CONIODES PLUMIGERARIA, Hulst. 



This insect was described from the $ only as Boarmia plumi- 

 geraria, Ento. Am. III., 216, 1887. In Bull. No. 7, new series, U. S. 

 Dept. Agric, p. 64, 1897, Mr. Coquillet publishes a life-history of the 

 insect, and gives us the information, apart from larval history, that the 

 female is wingless. I have received a specimen of the ^ from the 

 National Museum collection, which I herewith describe. 



Palpi short, rather light, separate, black or blackish-gray ; front 

 broad, black with a few gray scales; tongue very short, weak; thorax 

 blackish-gray, short, rather stout ; abdomen blackish-gray, very short and 

 heavy ; antennae filiform, blackish-gray, loosely scaled ; wings unde- 

 veloped, about as long as the thorax, blackish-gray, though lighter than 

 thorax and abdomen ; legs blackish-gray, rather long, slender, hind tibiae 

 with two pairs of spurs ; the abdomen is armed with chitinous spines, not 

 very stout, quite numerous over the whole segment, but hidden in the 

 covering scales. Upon closely examining the male I find that it also has 

 the abdomen armed with s])ines as in the female.
