Fabatana Walk. 



Fabatana oviplagalis Walk., Suppl. iv, 1260, 9, (1865). 



Asoj>ia anthoecioides G. & E., Tr. Ent. Soc. Phil. 15, pi. 2, fig. 9, 9 , (1867). 



I have before me only a single female, received from Mr. Dury (No. 

 13), from Cincinnati. The ocelli are present. It seems to be allied to 

 the following genus, of which I have no material before me to examine. 



SiPAROCERA Bobinson. 



Siparocera nobilis Eob., Ann. iST. Y. Lye. April, 1875. 

 Oecto-peria sincera Zell., Beitr. iii, 125, taf. x, fig. 45. 



New York ; Mr. Eobinson's type ( ^ ) I have seen in the Central Park 

 collection. 



Melanomma Grote. 



Male antennae bipectinate ; the branches separate, ciliate, before 

 their extremities bent, and with a longer exterior bristle. Ocelli pres- 

 ent. Maxillse moderate. Labial palpi with narrow and rather long 

 third joint, porrect, as long as the front. Clypeus rather narrow, 

 smooth, roundedly prominent. Fore wings with rounded costa, broad, 

 obovate, 12- veined, 4 and 5 separate, 5 from the cross-vein near 4; 6 

 irom the cross- vein opposite 5 ; 9 out of 8 a short furcation. Hind 

 wings 8-veiued; 2 from the median vein at beyond the middle; 3 and 

 4 from one point at the lower angle of the cell; 5 from the cross- vein 

 well separated from 4 ; the subcostal vein is quite distinct from the 

 costal (8), and throws off 6 and 7 beyond the closure of the cell ; 8 

 entirely freei, touching 7 at base, but then leaving it widely throughout 

 its course ; the cell has a median fold. I cannot detect the maxillary 

 palpi. This genus has a resemblance to Lederer's Brazilian genus 

 Cryptocosma in the pectinate antennae and the presence of metallic 

 marks on the gray wings. It differs very decidedly in structure, hav- 

 ing both ocelli and maxillse, and a totally distinct venation. The sepa- 

 ration of 8 and 7 on the hind wings is unusually complete in Melanomma, 

 except at base, where they touch without coinciding ; the fact that 3 

 and 4 spring together from lower angle of the cell, while 5 is more widely 

 separate, is interesting, and recalls other families; while the fore wings 

 are like the Pyralidw, the hind wings are like the Geometridce. I can see 

 also but two internal veins, but I have shown in other cases that the 

 character of three internal veins may not be considered as invariable in 

 the Pyralidce. The body is narrow, abdomen tapering, exceeding the 

 secondaries. 



Melanomma auricinctaria Grote, Tr, Ent. Soc. Phil. 117, 1875. 



^. I have one specimen only before me, received from Mr. E. L. Graef, 

 taken near Brooklyn, N. Y. The moth is gray, with transverse dark 

 lines, recalling Eupetliecia. The cell shows a black spot accompanied by
