914 GINDANES; HELIOPETES. By Dr. M. Draidt. 



59. Genus: CiJiiidaiies G. u. S. 



In the structure and exterior similar to the species of Pythonides of tlie higubris-gvou]) and chiefly 

 only distinguished by the peculiar shape of the wings. The apex of the forewing is cut off and the distal margin 

 strai"htly extends down to the end of the lower median vein, where it is deeply indented and runs obliciuely 

 to the proximal angle; hindwing below the apex almost laciniformly produced. The posterior tibiae exhibit 

 beside a hair-pencil 2 pair of spurs. Antennal apex somewhat longer and palpal terminal joint shorter. 

 hrehi^^^oii. G. brebisson Latr. (^ brebissonii A'«/., phagaesia Hew.) (178 c) is above light brown with a deep brown 



velvety spot in the middle of the forewing and smaller ones behind it, at the proximal angle of the forewing 

 and at the apex of the hindwing the distal margin of which, being situate below it, is dusted bluish-white. The 

 forewing exhibits besides at the exterior edge of the discal spot one large and several small hyaline spots. Beneath 

 the hindwing is light blue, at the costal margin and apex spotted somewhat blackish-brown. From Colombia 

 and Brazil. 



G. panaetius G. d- S. (178 c) is probably only the northern form of tlie preceding and merely distinguish- 

 ed by the oclu-eous-yellow, not blue under-surface of the hindwing, only tlie anal part being somewhat dusted 

 bluish-white. From Nicaragua and Panama. 



G, brontinus G. d: S. (178 c) is of a much darker brownish-grey, the hyaline spots are much more 

 reduced, and the dark discal spot is narrowed into a streak ; instead of them there is a broad, dark antemarginal 

 band. Under surface dark brownish-grey. Apparently only in Nicaragua. 



G. extensa Mab. It is doubtful to me, whether this species being described as Pterygospidea belongs 

 hereto. The wings are described to be yellowish-grey, forewing at the proximal angle deeply excised. Margin 

 brown, proximally dentate. 3 subapical hyaline dots in a brown band, between the upper median vein and 

 the middle radial vein a bipartite hyaline spot and below it a similar one in the submedian space; at the lower 

 cell-angle there is another hyaline dot in a brown spot. Hindwing below the apex very much gnawed out, at 

 the middle radial vein with a long booth with 3 faint, brown, small bands. Wings beneath light blue, the darkest 

 at the base of the hindwing with a black border as far as the tooth. Expanse of wings: 27 mm. Hunyabamba. 



60. Genus: Heliopetes Billh. 



It contains a number of rather homogeneous insects offering great difficulties as to the synonymy. 

 All of them are above more or less purely white, mostly with a black apex of the forewing. The medium-strong 

 antennal club is bent, the palpi are porrect, the 2nd joint covered with hairy scales, the terminal joint rather 

 slender, conical. Costal fold present; posterior tibiae beside two pair of spurs with a hair-pencil. 



(luiiiircJhi. H. domicella Erichs. (= willi Plolz. aconj'ta Plotz, adepta Plotz) (178 c) is the darkest species with 



a broadly blackened basal and distal part of the wings, so that only a broad white discal band is prominent 

 and the species almost looks like a Hesperia. Beneath similar, but duller, more olive-grey, particularly the 

 basal part of the hindwing is light and only defined towards the white discal band by an olive-grey band pointedly 

 bending inward in the cell towards the base. From Arizona and Mexico through almost the whole of South 

 America (Colombia, Guiana, Brazil to Argentina). 



arsalte. H. arsalte L. (178 c,d) is almost entirely white, only towards the apex along the ends of the veins 



on the forewing there appear black rays ; fringes speckled dark ; in the $ the apex of the wing is somewhat more 

 extensively smoked blackish, with a white, oblique subapical band. Beneath the veins are finely darker, on 

 the hindwing the lower median vein is somewhat darker. Widely distributed from Mexico to Paraguay and 

 in Jamaica, everywhere very common. 



■pctrua. H. petrus Hhn. (= niveus Hhn., laginia Heu\, bianca PJotz, Janice Ehrm.) (178 d) differs by a much 



broader and blacker apex of the forewing with a smoked subapical band in it; the margin of the hindwing is 

 likewise broader black. From the following alana it differs by the absence of the dark spots in the middle of 

 the hindwing beneath. From Nicaragua through Colombia, Guiana to the Amazon. 



aJanu. H. alana Reak. (= adusta Plotz) (178 d) resembles petrus above. Beneath on the ochreous-brown 



hindwing behind the cell and before the margin between the median and subcostal veins more or less distinct 



li<ja,ii(i. brownish spots. From Mexico to Brazil and Paraguay, everywhere common. — As f. ligania (178 e) Plotz 



figures a large, strong form with a v^ery broadly blackened apex of the forewing without a light subapical band 



'inaryiiKdis. and beneath only one spot between the median veins of the hindwing, no patria being stated. — f. marginalis 



Plotz (178d) from Peru is probably a form of it with a broadly blackened margin of the hindwing. 



nircUa. H. nivclla Mab. (= nivea Scddr. nee niveus Hbn., orbigera Mab., eidalia Plotz) (178 d) has above 



a narrowly blackened distal margin growing wider in the apex of the wing with traces of subapical spots, one
