THE SPECIES OF EUCOPTOCNEMIS. 



BY A. R. GROTE, A. M., BREMEN, GERMANY. 



In 1874 I proposed the generic term Eucoptocnemis for the Heliophobus 

 fimbriaris of Guenee, Noct. I., 172, whose statement that the species had 

 two terminal spines on the anterior tibire rendered its reference to the genus 

 Heliophobus of Boisduval improbable. In reality our species appears not 

 congeneric with the European Heliophobus hispidus. At the time of proposing 

 the genus I had no material. Later on I examined two or three specimens 

 taken near the coast of Massachusetts, but they were so worn that I 

 could not satisfactorily identify the species, while they probably belonged 

 to Guenee's fimbriaris. In a considerable collection from New York, 

 which I have identified for the Bremen Museum, I find, however, quite a 

 number of specimens which I determine as Guenee's fimbriaris ; the 

 material is generally well preserved, most of the insects are quite or 

 sufficiently perfect, and both sexes are represented. An examination 

 gives us the following structural characters : — The abbreviated anterior 

 tibiae show two longer terminal spines and a row of shorter spinules on 

 each side. Besides the pair of calcaria, the inner spur of which is 

 shortest, the middle tibiae are also provided with spinules ; the hind tibiae, 

 with two pair of spurs, are also armed. The testaceous legs are sparsely 

 clothed with pale hair (allowing the armature to be easily studied), and in 

 this respect showing affinity to our Western Cladocera niveivenosa, Grt. 

 The antennae are long, in the male finely bipectinate, the pectinations 

 gradually decreasing to the tips, in the female simple. The front is 

 smooth, without tubercle. The palpi are somewhat divaricate, with short 

 terminal article. The thorax is short and square, somewhat densely 

 clothed with hair-like scales, pilose. The abdomen is comparatively 

 short, not exceeding the secondaries, untufted, thinly scaled and rather 

 weak. Wings broad, with the fringes long and even, unicolorous. Eyes 

 naked, adorned with a variable pattern of black markings, unlashed. 



Eucoptocnemis fimbriaris, Guen., V., 172 (Heliophobus). 



Grt. Bull. B. S. N. S. I., (13), 1874, 

 96*5,493. Forewings broad, triangulate, silky, of a more. or less 

 determinate grayish-red, in some specimens the red is quite clear, some- 

 what brickish in tint ; this is the case in all the females examined. 

 Maculation subobsolete. Orbicular reduced to a dark or blackish spot, 

 which in one or two individuals shows a few central pale scales. Reni-
