NORTH AMERICAN ACROLOPHIDAE — HASBROUCK 531 



2b. Acrolophus griseus capitatus, new subspecies 



Figure 35 



Female. — Unknown. 



Male. — Head, labial palpi, antennae, and thorax ashy white. 

 Labial palpi elongate, recurved back over head and extending to 

 posterior margin of thorax, closely appressed to head and to each 

 other, densely clothed with large scales. Eyes large, protruding, 

 naked, without lashes. Antennae simple, laminate, covered dor- 

 solaterad with short scales, segmental processes set closely together 

 throughout antennae. Forewings with ground color ashy white, 

 markedly lighter than those of griseus griseus, sparsely and irregularly 

 furnished with spots and bars of fuscous scales; markings in form of 

 short bars along basal half of costa, distinct spot at outer end of cell, 

 slender bar above center of fold, and diffused patch below center of 

 fold. Hindwings brown, fringes grayish white. Legs and abdomen 

 pale brown. Wing expanse: 22 to 28 mm. 



Male genitalia.— The genitalia, except for the cucullus of the 

 harpe, are so similar between griseus capitatus and its companion 

 subspecies griseus griseus that the foregoing description of the latter's 

 genital structures should largely suffice for both. Those specimens 

 representing g. capitatus exhibit a type of cucullus shown in figure 35, 

 whereas my few specimens of g. griseus possess the type of cucullus 

 shown in figure 30. In g. capitatus, the cucullus constitutes a rela- 

 tively greater portion of the total length of the harpe, its basal and 

 central portions are much narrower, and only its approximate apical 

 third is broadly and evenly expanded dorsad and ventrad. A single 

 dissection has revealed these additional, although less marked, genital 

 differences in g. capitatus: the furcae of the uncus are very narrowly 

 separated throughout their entire lengths, the apex of the gnathos is 

 emarginate, and the spinelike process constituting the apex of the 

 aedeagus is rather short and very stout. A number of other minor 

 differences, such as those of setal arrangement, occur between the 

 two subspecies.

Remarks. — This subspecies probably ranges southward and west- 

 ward into Mexico. As has been shown above, the complex species,
