SATYRINAE: THE GENUS CERCYONIS. 157 



Protlioracic lobes very small, apjiresscd at base to a thin pellicle, siuldenly expand- 

 in{? above to a transverse tnniiil mass, com])aratively larjje, s^lobose and well i'oun(l(;d 

 interiorly, exteriorly extendin.ii: to a doAvnAvard enrvins;, digitate, blnntly pointed pro- 

 jection, taperinii l)oth in Iiei.ijlit and len<;tii; interiorly it is as lony; as hii;h and the 

 breadth exceeds tiie lenjith ai)ont fonr times. Patajria moderately convex, tiie posterior 

 lobe pretty t)road at Itase, scarcely twice as lonu; as broad, rapidly and pretty rej^rnhirly 

 tapirinii'. tlie interior I'dire nearly straiifht, the exterior concave, the tip ])luntly pointe<l. 

 Fore winns (38:1) not j^reatly prodnce<l at tiie apex; costal marjjhi pretty rej^ularly 

 thouiih not ijreatly convex thronghout; outer niartfin much the same, but more or less 

 flattened alona; the middle ; inner margin straight, the lower outer angle pretty well 

 rounded off. Costal nervui'c greatly swollen at the base for a distance equal to tlie 

 widtli of the cell ; first two superior subcostal nervules arising close to the tip of the 

 cell ; the latter a little less than half as long as the wing and but little more than twice 

 as long as broad ; median a little enlarged at the base, very gradually diminisliing in 

 size half Avay to its first divarication; submcdian Avith a basal enlargement similar to 

 that of the median. As an accessary sexual peculiarity, the male has the Avhole of tlie 

 upper surface of tiie cell and all the region innnediately surrounding it covered Avith 

 rather long recumbent hairs, directed from in front backAvard; there is also in the 

 loAver median interspace near its base and also beloAV and a little Avitliin it, as Avell as 

 in the medio-sul)median and submedio-internal interspaces, rather small, generally 

 triangular patches of partially erect scales, giving a peculiar appearance to thcAving. 



Hind wings Avith the costal margin ai-ched at the l)ase, pretty regularly convex 

 beyond, the upper outer angle very well rounded but a little prominent, outer border 

 scarcely angulated at the upper median nervule, on either side of it but little convex 

 and minutely crenulate ; inner margin slightly couA-ex, beyond the abdomen roundly 

 excised. Nervule closing the cell striking the median a little beyond its last divarica- 

 tion and the snl)costal as far beyond the basal curA'e of the loAvest branch; first median 

 nervule originating opposite the basal curve of the last subcostal nervule. 



Audroconia exceedingly slender, tapering from the very base to the merest thread 

 with great regularity, expanding at tip by a short and rather thick bunch of lateral 

 tlireadlets. 



Fore legs very small, cylindrical, the tibiae nearly one-third the length of the hind 

 tibiae ; tarsi not so long as the tibiae, consisting, in the male, of an undiAided joint, 

 terminated by a produced, constricted, conical apex, bearing a resemblance to a central 

 spine; in the female, of fiA'e very indistinct joints, the first three-fifths of the tai'sal 

 length, the others decreasing slightly and regularly to the tip and apparently quite un- 

 armed ; leg wholly unarmed excepting by the rather sparse clothing of long hairs, 

 which spread a little, especially on the outer side, and in the male more than in the 

 female ; middle tibiae a little more than three-fourths the length of the hind tibiae. 

 Tibiae furnished, on either side of the under surface, Avith a roAV of rather distant, 

 moderately long, forAvard and a little outAvard directed spines, the teniiinal ones de- 

 veloped into long and slender spurs ; first joint of tarsi longer than the next three 

 joints together, the second next in length and tAvice as long as the fourth Avhich is 

 shortest; the third and fifth equal; Avhole under surface of the tarsi liberally supplied 

 Avith rather shoi-t spines, confined mostly to a double median roAV and, on either side, 

 a lateral roAV, the latter the larger and their terminal spines in each joint slightly 

 curved and a little larger than the others; claAvs regularly and rather strongly curved, 

 quite slender, scarcely compressed, bluntly pointed ; pul villus minute, transversely OA'ate, 

 upon an enlarged peduncle; paronychia consisting on either side of two member's, an 

 upper, slender, straight, regularly tapering and very pointed lamina, as long as the 

 claAA'; and a lower, incurved, short, feathery, equal ribbon, half as long. 



Male abdominal appendages : upper organ rather slender, the centrum strongly com- 

 pressed, laterally triangular, scarcely arched above, the hook very slender and equal, 

 elegantly curved, its upper edge in direct continuation of that of the centrum, strongly 

 and e(|ually compressed, consiilerably longer than the centrum, bluntly pointed at tip; 

 sides of the centrum supporting near the middle a pair of lateral arms, slender, taper-
