We have two males of this species, which is very closely allied to C. virbius (Cram.), 

 but differs from it in having the primaries a little more elongate, and the white patch 

 on the secondaries not reaching the outer margin. We had at first referred this insect 

 to Carystus, but it seems better placed here. The genitalia of the male are very like 

 those of C. virbius, see Tab. XCVIII. fig. 16. 



b'. Secondaries immaculate above. 

 a". Primaries with one or two hyaline spots in the cell. 



2. Cobalus gabina, s P . n. (Tab. xcvm. figg. 17, 18, <? .) 



Alis fuscis, anticis maculis tribus in linea obliqua infra et ultra cellulam, ea in medio inter ramos medianos 

 prirnum et secundum maxima, aliis parvis, alia geminata in cellula, punctisque tribus in linea obliqua 

 subapicalibus, omnibus albo-hyalinis ; posticis regione costali obscurioribus : subtus ut supra, sed pallidi- 

 oribus, anticis area mediana obscuriore, macula ad venam submedianam multo majore ; palpis subtus 

 flavo-griseis.

A single male example is all we know of this species. It somewhat resembles 

 C. argus on the upperside, except that the hyaline spots in the cell of the primaries are 

 confluent, and that there are some minute additional subapical dots on these wings ; 

 the secondaries, however, are immaculate beneath. 



3. Cobalus argus. (Tab. XCVIII. figg. 19, 20, 21, 6 .) 



Carystus argus, Moschl. Verh. zool.-bot. Ges. Wien, xxviii. p. 212 (1878) '. 



Alis fuscis, anticis maculis quinque, duabus in cellula, superiore minuta, tribus in serie obliqua infra eas, ea 

 in medio maxima, omnibus albo-hyalinis : subtus griseis, anticis area mediana fusca, plaga supra venam 

 submedianam albida, punctis tribus subapicalibus nigrescentibus ; posticis maculis quinque, una magna in 

 cellula aliisque quatuor in serie irregulari (una interdum duabus oceliatis), nigris.
