186 A. R. Grote's Notes on the Zygsenidx of Cuba. 



on the upper side so as to form a parallel narrower ridge. A weak 

 veiulet, which I regard as the first sub-costal nervule, is thrown off at 

 apical third on costa, beyond the discal cross-veiu on the opposite side. 

 Before the apex, the sub-costal nervure furcates ; the upper branch 

 again very shortly dividing and forming the 2ud and 3rd s. c. nervules; 

 the lower branch, or 4th sub-costal nervule, runs straightly and down- 

 wardly obliquely, to external margin. Four median nervules; discal 

 cell closed. First and second m. nervules arising near together; third 

 farther removed, and fourth still more so. Internal nervure nearly 

 straight. Discal fold, obsolete. Secondaries, much reduced ; nervules, 

 short; discal cell, large, entirely closed. Four median nervules which 

 arise at gradually increasing distances, and are somewhat curved. 

 Legs, finely scaled, unarmed; posterior pair not unusually longer 



than the rest. 



This genus, which I fail to detect as already noticed by Authors, is 

 founded upon a small species with diaphanous wings, and allied to the 

 species I mention below, under Eunomia. H'dbn. It differs from 

 that genus structurally in the smaller palpi, the linear corporal parts, and 

 the peculiar development of the % genital appendages. In a single 

 female specimen the abdomen is shorter than in the male, and termi- 

 nates bluntty. Judging from this single 9 Burtia, that I have be- 

 fore me, the 9 antennae are impectiuate or more simple than in the 

 % . These are, however, so broken in the present instance, that I can- 

 not state the fact with certainty. 

 Burtia rubella, n. s. 



Sanguineous. Primaries, largely vitreous; extreme base sanguine- 

 ous. Costal edge narrowly dull-brown, as is the internal margin. An 

 aggregation of dark scales about the discal cross-vein, forming an elon- 

 gate discal spot, fused above with the costal scales. Terminally the 

 wing is covered with dull brown scales, forming a band widest at the 

 apex, narrowing to internal angle very rapidly. Two prominent san- 

 guineous spots, situate sub-apically on the interspaces, divided by the 

 fourth sub-costal nervule. Under surface, resembling upper. 



Secondaries, largely diaphanous, with a narrow, terminal, dark-brown 

 irregular band, distended at apex, and fringed towards aual angle and 

 partially along internal margin with sanguineous hairs. Under surface, 

 resembling upper. 



Clypeus, covered with brownish, close scales; palpi, whitish beneath, 

 brown at the tips and above, basal joints sauguineous. Head, behind, 

 "collar" and prothorax, sanguineous. Patagia and thoracic disc, dark
