AMALOPIS. 261 



as in Pedicla). Tibice with spurs at the tip ; empoiiia distinct ; ungues 

 smooth. Eyes pubescent ; front with a gibbosity ^behind the antenna ; 

 the latter 16-jointed, short (not reaching much beyond the collare when 

 bent backwards). Male forceps more or less club-shaped, with stout, 

 branched horny appendages. 



Rostrum short, with hxrge, hairy h'ps ; epistoma much broader 

 than long; palpi comparatively long ; the last joint is longer than 

 the preceding, but usually shorter than the two preceding joints 

 taken together.^ The eyes are pubescent, separated above by a 

 moderately broad front ; on the under side of the head, the space 

 separating them is narrow ; the gibbosity on the front, behind the 

 antennae, is sometimes small, but always perceptible. Antennje 

 16-jointed, very short; first and second joints of the usual shape; 

 the flagellum of some species (as A. vernalis 0. S., auripennis 

 O. S., immaculata M. ) is strongly incrassated at the basis, the joints 

 being closely packed together ; the tip is tapering and slender ; 

 in other species, however, this incrassation is not perceptible, and 

 the joints are well separated from each other {A. calcar 0. S.) ; 

 the under side of the flagellum, especially in the males, is clothed 

 Avith a short, dense pubescence ; the opposite side has longer, 

 verticillate hairs. Collare rather long, well developed ; thoracic 

 suture well marked. Feet long, moderately strong; the spurs at 

 the tip of the tibiae vary in length and distinctness; in A. calcar 

 they are very long and divaricate, and therefore conspicuous ; 

 much less so in the other species; front tarsi {%) rather long, 

 about once and a half or once and a quarter the length of the 

 tibia ; hind tarsi as long or a little longer than the tibia ; the four 

 last tarsal joints taken together are equal to three-quarters or 

 more of the first joint. The wings (compare Tab. II, fig. 14, 

 wing of A. calcar; fig. 15, of A. inconstans) are of moderate 

 breadth ; generally slightly broader in the female. The tip of the 

 auxiliary vein is nearly opposite the tip of the fifth longitudinal 

 vein ; the subcostal cross-vein is more or less anterior to the 

 origin of the second longitudinal vein ; the distance between 

 them is equal to about one length of the great cross-vein in A. 

 auripennis and calcar, two such lengths in A. inconstans, three 

 lengths or more in A. hijperborea, immaculata, and vernalis. 

 The tip of the first longitudinal vein is opposite the tip of the 



' I have observed the palpi of living specimens of A. calcar, inconstans, 

 and vernalis.
