 sometimes for the first segment; range: west of Rocky Mts.

1. Aplomerus lineatulus (Say) 



Anomalon lineatulus Say, 1836, Boston Journ. Nat. Hist., vol. 1, p. 244 (Leconte 



ed., vol. 2, p. 699); <?. Type: d\ Indiana (destroyed). 

 Aplomerus foutsi Rohwer, 1920, Proc. U. S. Nat. Mus., vol. 57, p. 454; ? . Type: 



9 , Cabin John, Md. (Washington). 

 Aplomerus decorus Viereck, 1926, Canadian Ent., vol. 58, p. 55; °. Type: ?, 



Fort Coulonge, Que. (Ottawa). 



Male: Front wing 2.8 to 7.0 mm. long. Structure similar to male 

 of A. robustus except that hairs tend to be longer, most noticeably 

 longer on the hind femur. The longer hairs near upper edge of hind 

 femur are about 0.3 to 0.45 as long as depth of femur. In robustus 

 and other species of Aplomerus these hairs are not more than about 

 0.25 as long as depth of femur. 



Black. Palpi stramineous; tegula and front and middle legs 

 fulvous; hind coxa entirely blackish or more or less stained with 

 fulvous; hind trochanters brownish fulvous; hind femur blackish, its 

 extreme base and apex brown; hind tibia fuscous, its basal 0.15 ± 

 brownish stramineous; hind tarsus brown; wings subhyaline. 



Female: Front wing 5.7 to 7.5 mm. long; hairs on head, thorax, 

 and legs longer than in any other species, some of the hairs exception- 

 ally long and suberect, these longer hairs on hind femur about 0.4 as 

 long as depth of femur (other species lack these long hairs and the 

 hairs on hind femur are less than 0.2 as long as depth of femur); 

 flagellum with 25 to 28 segments; head not strongly depressed, about 

 0.87 as high as long; temple moderately bulged and rounded; punctures 

 on temple coarse, separated by about 0.9 their diameter, sometimes 

 partly in irregular rows and with a weak wrinkle between each row; 

 notaulus foveolate; propodeal areola with strong bounding carinae; 

 sculpture of lateral propodeal areas weak; first abdominal tergite
