mens of fur cilia run below it. It is most like a smaXi jyortlandia, with 

 all the teeth exaggerated and everything darkened. The tendency to 

 darken the space between the median and transverse posterior line is 

 quite marked in most specimens. This is the only species in which the 

 orbicular is developed; but the dot which represents it is present in all 

 the specimens I have had. before me.

 Demas Stkphexs, 111. Brit. Ent., Haust., 1829, II, p. 59. 



Plump, yet somewhat slightly built species, with retracted head, 

 very short thorax, long, cylindrical abdomen, and large, narrowly 

 trigonate primaries. 



Head strongly retracted, broader in the male than in the female, 

 front flat. Tongue short and weak, useless for taking food. l*alpi 

 scarcely reaching the front and very slender. Eyes hairy. Ocelli very 

 small and concealed. Antennae lengthily and heavily pectinated in 

 the male, simple in the female; seeming short in jiroportion to the wings. 



Thorax very short and weak, wider than long, collar and patagiae 

 well marked, vestiture composed of flattened hair and scales, forming- 

 no tufts. The legs are short and stout, yet weak in proportion to the 

 body, clothed with lengthy hair and scales. No armature, except the 

 usual spurs, which are well developed and subequal. 



Abdomen long, exceeding the anal angle of the secondaries in both 

 sexes; longer and more cylindrical in the female. No tuftings. 



iChe wings are of good size, large in proportion to the thorax. 

 Primaries with the costa and inner margin arched so that the wing 

 widens rathtr abrui^tly at base; outer margin oblique, arquate, the 

 apices rectangular rather than pointed. Venation normal, except that 

 the accessory cell is narrow, sometimes stalked beyond the cell, and 

 occasionally wanting entirely. As a rule, 7, 8, 9, and 10 are very close 

 together from the end of the small cell; when that is absent the stalk 

 continuing the subcostal gives off in order 10, 7, 8, 9. 



Secondaries proportionate, rather narrow, venation normal, save that 

 5 is as strong as any others and arises close to 4 from the median vein. 



The genus is closely related to Panthea, and ditt'ers chiefly in the form 

 of the primaries, which are less triangular, Avith more arched costa and 

 more abruptly widened inner margin. The thorax seems yet smaller 

 and more weak and the head more retracted, leaving the abdomen of 

 disproportionate length, especially in the female. The antennae, espe- 

 cially of the nuile, seem unusually short, though this is less marked in 

 j)alata than in the other species. In all, however, the pectinations are 

 proportionately longer than in those of Panthea. 



Three species are recognized as belonging here, liropinquilinea and 

 flavicornis being closely allied, whi\e palata is very distinct. 



Propinquilinea resembles Panthea in the form of the median lines, 

 which are single and quite well marked; but the transverse posterior
