ceropalinae: tribe ceropalini 241 



Punctures on mesopleuron separated by about 1.2 their diameter; longer 

 hairs on top of head light brown, longer than in C. pacifica; second flagellar 

 segment about 1.3 as long as wide; male subgenital plate with a rounded tip 

 and when dry with a pair of subparallel longitudinal wrinkles beneath that 

 may continue separately to the apex or unite into a single longitudinal 

 wrinkle which continues to the apex; female subgenital plate shorter. 



9. rugata, new species 

 22. Hind femur rufous; female subgenital plate a little longer; smaller punctures 



of thorax sharp 10. femoralis Cresson 



Hind femur blackish; female subgenital plate a little shorter; smaller punctures 

 of thorax rather weak 11. hatoda Brimley 



MACULATA GROUP 



Forewiiig 4 to 9.5 mm. long; body rather slender; antenna a little 

 longer and more slender than in the other species groups; longer hairs 

 of frons suberect, rather short and sparse; longer hairs on mesoscutum 

 short, inconspicuous; second to fourth segments of fore and middle 

 tarsi of male not unusually short, the second segment of middle tarsus 

 about 2.0 as long as wide; last segment of fore tarsus of male with a 

 median thumblike lobe on the front side; claws on fore and middle 

 tarsi of male with an acute upright tooth, the tooth small and subapical 

 on the claws of the middle tarsus, and on the hind claw of the front 

 tarsus, larger, subbasal, and somewhat appressed on the front claw of 

 the front tarsus; claws on fore and middle tarsi of female with a short, 

 acute, upright, subapical tooth; male subgenital plate semicircular, 

 the margin thin and curled down; female subgenital plate in profile 

 with a projecting apical part whose apex is evenly rounded; male 

 cerci in the form of subcircular flaps that usually protrude beyond the 

 seventh tergite. 



The only species of this group laiowm to me is the Holarctic polytypic 

 C. maculata. 



1. Ceropales maculata Fabricius 



Forewing 4 to 9.5 mm. long; head and thorax opaque, with small 

 sharp adjacent punctures; mesoscutum with the larger punctures 

 sharp, separated by about theu- diameter; mesopleuron %vith the larger 

 punctures somewhat weaker, separated by about twice their diameter. 

 Wings subh3'aline. 



This is a Holarctic species with a number of subspecies. The typical 

 subspecies, which is European and included for comparison, and the 

 three Nearctic subspecies are described below.
