Plagiomimicus Grote. 



I called attention some years ago in the Bulletin of the Buffalo Society 

 to the resemblance between this genus and Polenta, in the spreading 

 thoracic tuftings, the modification of the clypeus, the shape of the wing 

 and the peculiar pattern of marking, which is so much alike that the two 

 species would be considered congeneric by most observers. I since con- 

 tradict Mr. Morrison's observation that the fore tibise are unarmed in 

 Polenta ; this was the best distinction. The discovery of new forms 

 confirms me that the genera I have grouped under Stiriincs. are all 

 valid, the modifications of structure being apparent and going closely with 

 the pattern. Stlbadium approaches Telestlla, in frosting and sheen 

 (aureolum), and leads to this genus as before suggested. With the new 

 species the group (without absolute value) may fall in between Calpe and 

 Phtsia. 



Oxycnemis, >i. ^. 



Vestiture flattened hairs ; a tuft behind thorax of broad curved shining 

 scales widening to their tips ; abdomen short, untufted. Size small, body 

 slender. Hadeni-form ornamentation. Eyes naked, unlashed. Fore 

 tibiae with the whole short broad joint corneous, terminating in a stout 

 central claw or spine ; the legs slender, otherwise unarmed. Notwitl:- 

 standing its Hadeni-form look, the insect appears nearest to Triocnemis. 



Oxycnemis advena, ft. s. 



^ . Gray, neatly lined, with the bright color and ornamentation 

 recalling Charadra palata. T. a. line black, distinct, upright, attached to 

 the large open claviform. Discal stigmata light gray, subequal, with 

 included dots. T. p. line faint. S. t. line black with a following white 

 shade, marked with black on costa, far from margin and easily taken for 

 t. p. line, curved in inferiorly ; veins terminally finely marked in black. 

 Hind wings pale fuscous, whitish at base. A white costal shade on pri- 

 maries above from inception of s. t. line over the disk. Size small.
