ACANTHINA PLANA. 



Foem. Nigra, albido tomentosa ; antennce fulvce, latce, basi et apice 

 nigricantes ; thorax vix attenuatus, vittis duabus dorsalibus 

 cinereo iomentosis ; scutellum dentibus duabus validis testaceis 

 armatum ; abdomen ovatum, subcontractum, fere planum, 

 thorace paullo longius et latius ; tarsi posteriores fulvi ; alee 

 cinerascentes, albido unifasciatce. 



Fcem. Black, thinly covered beneath with whitish tornentum. 

 Antennae tawny, broad, compressed, fusiform, blackish at the base 

 and at the tips. Thorax very slightly convex, a little narrower, but 

 hardly lengthened in front, with two dorsal stripes of cinereous 

 tornentum. Scutellum armed with two rather long and stout testa- 

 ceous teeth. Abdomen oval, slightly contracted, nearly flat, a little 

 longer and broader than the thorax. Posterior tarsi tawny, with 

 black tips. Wings gray, dark gray along each side of a whitish 

 band, which extends from the costa beyond the middle, and does 

 not join the hind border ; veins black ; first branch of the cubital 

 vein ending at full two-thirds of the distance between the radial 

 and the second branch ; four externo-medial veins, the third not 

 extending to the border; discal areolet heptagonal. Length of the 

 body 2 lines ; of the wings 3^ lines. 



This species differs still more than the preceding from the 

 typical form of Acanthina, and appears to be a connecting link be- 

 tween that genus and Clitellaria, and, like many other species, its 

 characters require an alteration in the diagnosis of the genus 

 to which it is assigned, or the formation of a new genus.

Note. — Clitellaria Halala, C. Amenides, and C. varia are very 

 nearly allied to Acanthina, which ought, perhaps, to be united to 

 Clitellaria.

Genus PUOMEEANISA. 



Foem. Caput antice conicum, valde elongatum. Antennae 

 6-articulatae, capitis longitudine, basi approximatae ; articulus lus 

 compressus, fere rotundus ; 2us brevis ; 3us et sequentes longi, 

 lineares, cylindrici, arete conjuncti; 4us 3o brevior; 5us 3o multo 

 longior ; 6us 4o aequalis. Scutellum bispinosum.
