AMERICAN LEPIDOPTERA. .) 



Species gray to dark fuscou.s-brown. Dorsal margin of forewings with mark- 

 ings, cilia more or less distinctly barred. First joint of labial palpi 

 with distinct brush and lateral setje strongly marked . . .Group III. 



SECTION I. 



The four species comprising this section may be separated as fol- 

 lows : 



Forewings less elongate, apex broadly rounded. 



Markings of forewings not confluent bren i pen n«'l la. 



Markings confluent efrenatella. 



Forewings elongate, apex obtusely rounded. 



Larger, 20-23 mm.; ground color giayish-oehreous colorariel la . 



Smaller, 14-15 mm. ; color pale ochreous ari/micl la . 



A. l»r<- v i |»4>n lid la n. sp.— Pale ochreous as bone-yellow. First and second 

 joints of labial palpi fuscous, except apical part of latter, brush large, scarcely ex- 

 tending beyond end of second joint, third joint fully as long as the second, 

 pointed, slightly compressed, thinly dusted with fuscous. Vertex and antenna' 

 ochreous-brown, the latter rather stout. Thorax ochreous-brown, tinged with 

 fuscous and having somewhat of a metallic lustre. Abdomen dusted with fus- 

 cous. Forewings rather wide, oval, costa evenly arched from base to apex, latter 

 broadly rounded, pale ochreous, dusted and marked with fuscous. A large rhom- 

 boidal spot at base of costa extending to fold, another large spot at one-third, 

 beyond the latter are two or three small dots, and beyond the middle are five costal 

 spots, decreasing in size, the first two of these extend more or less distinctly into 

 the disk and are connected with a large, nearly quadrate spot at the end of cell ; 

 a row of spots, more or less connected at base of dorsal cilia, immediately below 

 the two basal spots on the costa, are two longitudinal dashes, a streak on the fold, 

 more or less interrupted, several dots above end of fold. Cilia pale ochreous, with 

 dark dividing line. Hindwings grayish ochreous, finely dusted with fuscous, 

 cilia paler with well marked subbasal line. Underside of wings grayish fuscous. 

 Body beneath and legs, silvery grayish white, anterior and middle legs strongly 

 spotted with fuscous brown, tarsal joints pale at apex. 



Exp. 14.0-15.0 mm. ; 0.56-6.0 inch. 



Hub. — District of Columbia, Maryland (Flummer's Island). 



Numerous specimens were taken at above localities by Mr. A. 

 Busck, who also has kindly placed several specimens in my cabinet. 

 Quite distinct; its nearest ally is efrenatella Clem., which it resem- 

 bles in markings, but from which it differs by the relatively shorter 

 forewings, broadly rounded at the apex. 



A . efrenatella Clem.(Dyars List, p. 573, No. 6534).— General color ochreous. 

 Labial palpi except the third joint, dark fuscous externally, slightly so within, 

 brush very dense, third joint pointed, distinctly compressed, scarcely as long as 

 the second. Head, antennae and thorax ochreous-brown, the latter fuscous ante- 

 riorly. Forewings rather wide, costa feebly curved from the base and again
