c? ? . Tongue as long as the body or longer. Gciial process nearly reaching 

 end of pilifer. Labrnm raised mesially into a rounded tnbercle, truncate in front. 

 Knd-segment of antenna long, thin, clothed with long dispersed and half erect 

 scales. Palpus large, terminal surface in a plane with frons, segment 3 minute, 

 2 shorter but somewhat broader than 1. Eye large, feebly or not at all lashed. 

 Tibiae icitftoiil spine/i.* First segment of midtarsns with a comb of long bristles 

 near base ; first segment of anterior- tarsus with a number of spines at base 

 exteriorly, besides the usual external row, some of the sj)ines of the tegment long in 

 a number of species. Spurs nnequal, long terminal one of hindtibia varying in tiie 

 different species from one-half to three-quarters the length of the first tarsal segment. 

 Jlesoiiofum with a short double crest of scales in many si)ecies. I'nlvillus present 

 or absent ; jiaronychinm always present, with one lobe on each side. 



c?. Antenna in some species (Carolina, dilucida, afflicta, etc.) obviously longer 

 and thicker than in others {lucctuts, petuniae, etc.) ; segments laterally impressed, 

 ciliae of basal row short ventrally, the distal row of ciliae not extending to the 

 ventral surface. Tenth tergitc slender, more or less slightly hook-shaped, dorsally 

 impressed in middle jnxixinially, ventrally subcariuate before end, with dispersed 

 erect or suberect hairs, tip pointed or slightly sinnate ; tenth sternite with a mesial 

 lobe which varies in length in the genus, the lobe often canoe-shaped, witli the 

 end truncate or sinuate. Penis-sheath armed at or before end with a prominent, 

 triangular, comjiressed, more or less horizontal tooth, which is sometimes replaced 

 by one or two small ones ; three minutely grannlose, membranaceous, com- 

 pressed lobes in the interior of the sheath (PI. XXIX. f. 21). The clasper is 

 sole-shaped ; its upper margin dilated before end and turned inward in all species 

 e.\cej)t lefchurei ; the inner surface is densely clothed with stiff hairs, which jioint 

 dorsad and ])roximad ; harpe normally with a ventral, more or less horizontal, hook, 

 and a large dentate process or ridge lying more or less flat on the inner surface 

 of the clasper. In one species {nistica) the ventral hook alone is preserved ; in 

 others (or/at.s, Icfi'hurei, petimi(tc) the dentate part is reduced in size, while in others 

 again {^/{orcslan, srstjuiplcx, trim/icula, etc., etc.) there is no ventral hook ; the 

 hai-jJB of (lalica (= garlejjpi) stands intermediate between the second and third 

 harpe-form. In all species there is a conspicuous jiatch of snberect scales (generally 

 white) at the base of the dentate lobe of the harpe, rii.stica without such a lobe 

 being alone an exception. 



? . The antenual segments are not, or very feebly, impressed laterally ; the 

 basal ciliae are sometimes slightly prolonged (this is especially the case in 



* P. quinqfiemaculatu^ alone has a few spines at the tip of the foretibia.
