and Hecabolus as much as the two latter genera differ from each 

 other. 



Genus HERATEMIS. 



Mas. Corpus glabrum. Caput transversum, thorace latius. Palpi 

 graciles, longiusculi. Antennae graciles, filiformes, corpore vix 

 duplo longiores. Thorax robustus. Abdomen sessile, lineare, 

 depressum, angustum. Pedes longi, graciles. 



Male. Nearly allied to Ccelinius. Body smooth, shining. Head 

 transverse, broader than the thorax. Palpi slender, rather long. 

 Antennae slender, filiform, almost twice the length of the body ; 

 joints elongate, numerous, closely joined together. Thorax robust ; 

 sutures of the parapsides strongly marked. Abdomen sessile, 

 linear, depressed, a little longer and much narrower than the 

 thorax. Legs long, slender. Wings moderately broad ; fore 

 wings like those of Ccelinius in the structure of the veins. 



HERATEMIS FILOSA. Mas. Rufa, capite nigro, antennis nigris basi 

 pallide rufis, pedibus testaceis, tibiis tarsisque posticis nigris, alis 

 nigricantibus, venis stigmateque nigris. 



Male. Red, paler beneath. Head black. Antennae black, pale 

 red at the base. Legs testaceous ; hind tibiae, hind tarsi, and tips 

 of hind femora black. Wings blackish ; veins and stigma black. 

 Length of the body 2i lines ; of the wings 4 lines. 



Genus NEBARTHA. 



Mas. Corpus gracile, elongatum, scitissime punctatum. Caput 

 transversum, sat parvum. Palpi graciles, longiusculi. Antennae 

 filiformes, sat graciles, corpore breviores ; articuli elongati. Tho- 

 rax fusiformis. Abdomen fusiforme, subsessile, thorace vix lon- 

 gius. Pedes longi, graciles ; postici robusti, longissimi, 



Male. Allied to Ccelinius. Body slender, elongate, slightly 

 shining, very finely punctured. Head transverse, hardly as 

 broad as the thorax. Palpi slender, rather long. Antennae fili- 

 form, rather slender, shorter than the body; joints elongate. 

 Thorax fusiform ; metathorax well developed. Abdomen fusi- 

 form, subsessile, as broad as the thorax, but hardly longer. Legs 

 long, slender ; hind legs robust, very long. Wings moderately- 

 broad ; structure of the veins hardly differing from that of Coeli- 

 nius. 



NEBARTHA MACROPODIDES. Mas. Fulva, capite gutta nigra, antennis 

 piceis basi fulvis, thorace abdomineque nigro bivittatis, femoribus 

 intermediis nigro fasciatis, femoribus posticis dimidio apicali nigro, 

 alis obscure cinereis, venis nigris, stigmate pallide piceo. 



Male. Tawny. Head with a black dot between the eyes. An- 

 tennae piceous, tawny at the base. Thorax and abdomen with a 

 black stripe along each side. Middle femora with a black band 

 near the tips. Hind femora with the apical half black. Wings 

 dark cinereous ; veins black ; stigma pale piceous. Length of the 

 body 2f lines ; of the wings 4j- lines.
