880 PHAEDINUS; COCCEIUS. By Dr. M. Drattdt. 



mexicamis. Th. mexicanus H.-Schaff. (= nevada Scdd., ananius Plotz) (171 b). Above brown with scanty, small 



discal hyaline spots; fringes of the forewings speckled, on the hindwing light, almost unspeckled. Beneath 

 the brown wings are very much strewn "«-ith a \i-hitish-grey towards the margins, unmarked, before this the 

 hindwing shows two broad, faded transverse bands. From the Rockey IMountams through California to Mexico. 



daunus. Th. daunus Cr. (= bathyllus Swsn.) (171 b) is similar, larger, with larger hyaline spots and also 



on the hindwing with somewhat speckled fringes. Beneath likewise similar, but the marginal area is not so 

 light strewn whitish-grey, the transverse bands are more or less lead-colom'ed. In the south of the Atlantic 

 United States. — ■ The green larva with a yellowish subdorsal stripe, red collar and black head, lives on Papi- 

 lionaceae, such as Glycine, and pupates on the stalk of the food-plant. 



paucipiinc- Th. paucipuiicta Dyar (171 c) is very closelj'^ allied to daunus, somewhat smaller, the discal spots 



ia- very much reduced, often scarcely visible. Beneath likewise similar, the forewing towards the margm scarcely 

 brightened up, the hindwing only in the middle of the distal margin, otherwise with the same transverse lines; 

 fringes of the hindwing almost white. Sierra de Guerrero (Mexico). 



mysie. Th. mysie Dyar (171 b, c) is considerably larger, above very light fawn-colom-ed, the hyaliiie spots 



somewhat more reduced than in daunus, the fringes of the hindwing somewhat speckled. Beneath marked 

 as the other species on a ground very much strewn with a whitish grey, with 2 irregularly spotted transverse 

 bands, the proximal one darker. From Mexico. 



fhedea. Th. thedea Dyar looks above somewhat like Cogia eluina (170 e, f): brown with a blackish transverse 



band through the middle, on the median veins distally dentate, behind it two small white spots in the cell and 

 one at the costal margin, before the apex 4 minute hyaline spots; some more, small, antemarginal spots are 

 ringed blackish : one above the upper median vein, a double one above the lower, and a double one above the 

 inner-margmal vein. Hindwing with traces of a postmedian row of spots. Expanse of wings: 40 mm. Mexico 

 (Tehuacan). 



uvydixa. Th. uvydixa Dyar (171 c) is the largest, most beautiful species of the genus, above nut-coloured brown, 



outside darker, with the hyalme spots of daunus and very dark-speckled fringes. Beneath the hindwmg is 

 almost white in the larger distal half, with 2 fine, distinctly black dentate lines ; on the forewing an antemarginal 

 line of light moon-spots. Mexico (Guerrero), taken in June. 



41. Genus: Phaediuus G, d; S. 



Very closely allied to the preceding genus, distinguished by a much longer 3rd palpal joint which is 

 porrect; the antennal apex is turned down and shorter. 



caicus. Ph. caicus H.-Schaff. (= moschus Edw., schafferi PZdte) (171 c) looks above almost like y/ior. cZawwiiS, 



but the discal spots are somewhat narrower. The frmges of the forewmg brow^nish, speckled darker, the fringes 

 of the hindwings almost white. Beneath the hindwing is not so brightly strew^l, with two broad, lead-coloured 

 black transverse bands, the proximal one broken up into 2 spots. Arizona and Mexico. 



aventinus. Ph. aventinus G. cfc S. (173 b) is somewhat like caicus, smaller, with more extended hindwings 



and quite dark fringes. The hyalme spots of the forewings are much smaller, almost punctiform and more 

 numerous. The under surface is quite mii-coloured dark, almost without any traces of transverse bands. De- 

 scribed from Mexico. 



42. Genus: Coceeius G. & S. 



Distmguished from the preceding only hy the presence of a costal fold in the ^. 



pylades. C. pylades Scdd. (171 b) is the most similar to Thorybes mexicanus (171 b), only somewhat larger 



with somewhat larger discal hyaline spots, all the fringes distinctly speckled. Beneath the marginal part is 

 not so very bright, the 2 macular bands on the hindwing are somewhat narrower. Atlantic States. 



drusius. C. drusius Edw. looks like Ph. caicus (171 c), it has less and smaller hyaline spots arranged some- 



w'hat differently. The under surface is darker, the bands of the hmdwings indistinct; on the ventral side of 

 the abdomen the ventral line is absent ; the palpi are dark grey, mixed with brown, in caicus yellowish. Expanse 

 of wings: 1.7 inches. Southern Arizona. 



syloson. C. syloson 31 ab. is as large as Th. daunus (171 b). On the forewing there is an oblique band com- 



posed of 5 hyaline spots, the spot above the upper median vein projects towards the margin. Fringes of the 

 forewiiig broad, in the middle dark, towards the apex and proximal angle whitish, the fringes of the hindwing 

 almost white; speckled dark. Beneath the hindwing is blackish, traversed by 2 still darker macular bands. 

 Described from Cayenne.
