PSYCHE. 



91 



more prominent than the lateral canthi 

 of the scutellate disk beside it ; process 

 of metazona a little obtusangulate, rarely 

 rectangulate ; contrasted markings of 

 tegmina confined to the costal field ; 

 wings relatively narrow, twice or more 

 than twice as long as broad; hind tibiae 

 yellow, occasionally faintly tinged with 

 glaucous. 



U^. Front lobe of median carina of pro- 

 notum not prominent ; lower posterior 

 corner of lateral lobes distinctly angu- 

 late in female : wings pellucid, but 

 with the basal half or less roseate, 

 sometimes with feeble indications of a 

 transverse band beyond by the broad- 

 er infuscation of the cross-veins. 



rosaccnm. 

 l>~. Front lobe of median carina of 

 pronotum distinctly cristate ; lower 

 posterior corner of lateral lobes well 

 rounded in both sexes; wings wholly 

 pellucid except for the apical infusca- 

 tion of some of the anterior veins, with 

 no signs of a transverse band. 



hyaliniDii. 

 a^. Median carina of pronotum crested 

 l)etween the sulci, here forming a dis- 

 tinctly rounded lobe ; process of met- 

 azona rectangulate or subrectangulate ; 

 contra.sted markings of tegmina crossing 

 the discoidal as well as the costal field ; 

 wings relatively broad, distinctly less 

 than twice as long as broad ; hind tibiae 

 blue. . . . kioii'a. 



Mestobregma rosaceum sp. nov. 



Fenii>;iiieo-testaceoiis, much marked with 

 fuscous. Head salient, fenugineo-testaceous, 



in the male paler than in the female and also 

 often marked above with longiludinal fiiscon.s 

 strlpe.s, and with a slender transverse line 

 between the eves, also found in the female; 

 fastigiiim of vertex brief, deeply sulcate, par- 

 ticularly in the male, with a distinct median 

 carina, the bhaip margins of the fa.stigiinn 

 continuous with the margins of the deeply 

 sulcate frontal co,sta, which is narrow, slightly 

 expanded at the ocellus, and broadens a little 

 below; eyes prominent, particularly in the 

 male; antennae a little {$') or considerably 

 (?) shorter than the hind femora, testaceous 

 annulate with fuscous or the reverse. Pro- 

 notum hardly longer than broad, mesi;illy 

 a little constricted, above of the color of 

 the head, the lower portions of the lateral 

 lobes clay-yellow, margined above with black 

 fading into fuscous or ferruginous, the disk 

 more or less (in the male conspicuously) 

 marked witli short longitudinal fuscous 

 sti'ipes, often with flavous interspaces; me- 

 dian carina no more elevated on the prozona 

 than on the metazona or than the canthi of 

 the scutellum, which is not at all |ironounced ; 

 process of metazona a little obtusangulate; 

 lower margin of lateral lobes with a distinct 

 posterior depending denticulation in the fe- 

 male, the angle subrectangulate and rounded 

 in the male. Tegmina very long and .sub- 

 equal, feebly maculate throtighout, but with 

 the contrasted markings not very marked 

 and confined to the costal field, which is 

 mostly fuscous with a pale cinereous spot just 

 beyond the widest part; wings fully twice as 

 long as broad, pellucid with fuscous veins 

 and the basal half or less tinged with rosa- 

 ceous, tlie costal margin infuscated beyond 

 the middle, and sometimes the indications of 

 a mesial cross-band in the deeper infusca- 

 tion of the cross-veins . Hind femora cinere- 

 ous marked with fuscous, and especially with 

 two fuscous spots above, at and beyond the 

 middle; hind tibiae pale yellow, occasionally 

 a little embrowned, especially beneath.
