NOVITATES ZOOLOGICAE XXIII. 1916. 169 



isolated (except for some very feeble greyish shading) from the postmedian band. 

 Hindwing beneath with both the dark bands strong and sharply defined, the ground- 

 colour, especially between them, more whitish than in trimaculata, quite free from 

 grey clouding. 



Sapucay, Paraguay, November 23, 1904 (W. Foster). Type in coll. Tring Mus. 



A single £ from the same source, September 15, 1904, is considerably smaller 

 (30 mm.) ; forewing with apex less produced, antemedian line indicated, the dark 

 cloud being absent on upperside ; hindwing with termen less strongly bent in 

 middle. Its absolute agreement with the ? type in all other respects (except of 

 course the shorter palpus) seems to leave no doubt as to its identity ; but the 

 pectinations are shorter (scarcely over three times diameter of shaft), and this is 

 such an unexampled phenomenon in the lepidoptera that I have made the more 

 striking ? the type. No other species of the group is yet known from Paraguay. 



44. Dichorda rhodocephala sp. nov. 



c?, 26-30 mm. ; ?, 36 mm. Head predominantly red, even the white crown 

 being spotted or mixed with red ; the occiput red. Palpus dark purple-red, first 

 and second joints white beneath. Antenna proximally red ; in ? not pectinate. 

 Thorax and base of abdomen green above ; the rest of abdomen mostly dirty pale 

 ochreous, second tergite with a large, third with a small white spot at end, narrowly 

 edged, except behind, with red. Fore and middle femora and tibiae with dark 

 purple-red spot at end, that of foretibia extended proximally so as to cover a large 

 part of the joint. 



Forewing with SC 1 free ; bright uniform green, as in rectaria Grote ; costal 

 edge dark purple-red nearly to apex (most broadly towards base), somewhat spotted 

 (scarcely at base) with white ; first line obsolete ; cell-dot minute ; postmedian line 

 whitish, with slight suggestion of narrow dark yellow-green edging proximally, 



nearly straight from beyond five-sixths costa to two-thirds hindmargin. 



Hindwing without red costa or dark discal dot ; line continued, straight, ending 

 at nearly two-thirds abdominal margin. 



Forewing beneath paler green, becoming whitish posteriorly ; costal edge 

 narrowly ochreous-whitish, spotted with red ; cell-dot present; line feebly indicated. 

 Hindwing whitish green, a little brighter at apex and along anterior part of termen; 

 white line indicated. 



Jamaica, 2 3<$, 1 ? in coll. Tring Mns. 



Nearest rectaria Grote, from North America, distinguished by the redder head, 

 the abdominal ornamentation, obsolescence of first line, etc. Seems to have been 

 confused with the very different iris Butl. (Amazons and Peru), of which uniformis 

 Warr. (Trinidad, Colombia, Venezuela, and the Guianas) is the more northerly 

 representative. In both these the ? antenna is bipectinate. 



Racheolopha Warr. 



When I prepared fascicule 129 of Genera Insectorum, I was greatly in 

 doubt about this genus, being unable to study the species on which its author 

 founded it (miccularia, Guen.. Warr. det.) ; and to add to the confusion, I un- 

 accountably attributed to rufilimes Warr. a 4-spurred hindtibia. I have now seen 

 the specimen which Mr. Warren had before him, besides several other examples 

 of the same species (= imula Dogn.), and canjprovisionally accept it as GueneVs
