scales; 2) collar (patagia) dark brown: 3) apicos of forewings more 

 obtuse; 4) termen more convex; 5) hindwings more elongate; 6) median 

 fascia on their underside rectangular, 7) colour of cilia at apices whi- 

 tish; 8) much longer first tibial spurs; 9) two subequal dentations of 

 the postmedial line: 10) base of hindwings on the underside black, 

 with no white spots and fasciae; etc., etc. 



From C. Judith S t r e с к. var. miranda Ну. Ed w. ^) my species 

 differs in having — 1) markings on forewings obsolete; 2) cilia gray; 

 3) no white fasciae on the underside; etc. 



It is needless to enumerate the distinctive characters of G. orha 

 from other blackwinged forms of nearctic fauna. 



The discription is made, and figure photographed, from a male 

 specimen taken in Texas, U. S. A. (without detailed indication of loca- 

 lity), and received from Mr. W. Neuburger in Berlin. I am very 

 indebted to my esteemed entomological friend Mr. Oscar John in 

 St. Petersburg, who has put tliis specimen at my disposal. Now it is 

 preserved in my collection. 



Final determination of the exact position of C. orha in the genus 

 can not be made till much more is known than at present. I have al- 

 ready had the occasion*) to give my opinion of the modern classifica- 

 tion of the genus in general, and of the unnatural erection of the 

 „blackwinged" group of species in particular. T am inclined to believe 

 that many species in the genus want careful revision. 



marks, followed by white, very distinct. Thorax like forewings, Avitli mixed 

 black scales on the collar and tegulae. Hindwings black with blackish fringes. 

 Abdomen above with a blackish shade. Beneath, the body parts are white; se- 

 cond joint of palpi black. The wings are white at base, with narrow pale inter- 

 spaces between the bands, and resemble generally the other species. Expanse 

 45 to 50 mm.". 



■^) The original description of C. miromhi by Ну. Edwards (Papilio, 

 I, 1881, p. 118) is as follows: 



„Allied to levettei G r о t o, and probably confounded with it in collections. 

 It is however smaller, with the primaries of a clearer gray, and with the lines 

 sharper and more distinct. The t. a. line is oblique, and very slightly dentatod, 

 reaching the internal margin at a point very near the middle, and almost 

 connected there with the t. p. line which runs into a long tooth on the lower 

 submedian nervule. The reniforra is well defined, gray, surrounded by a Avhi- 

 tish cloud. Secondaries black, with the fringes clear white, thus presenting a 

 strong ))oint of difference from C. levettei. Tlie thorax has the collar brown 

 and well marked. Underside smoky brown with the apices, a submarginal band 

 on the primaries, as well as the fringes of secondaries white. Expanse of 

 wings 1.75 inch.".
