Differs from the other species of this section of Myssodrys in the less elongated and 
subtriangular form of the lower lobe of the eyes. The pro- and mesosternum are nearly 
as in Leiopus nebulosus; and I should have placed the species in Letopus had the 
antenne not differed so greatly from that genus in their length and tenuity.

The Central-American form of this species differs constantly in general colour and 
markings from the Amazonian type, and merits a distinctive name :— 
Var. WV. ocellata. A typo differt colore ochraceo-fusco sicut in NV. deleta, inter fascias nunquam cinereo; fascia 
mediana undulata angustiori, fasciaque anteapicali semper multo abbreviata, punctiformi, signaturis 
omnibus letius et distinctius cinereo-ochraceo marginatis.

N. efflicte quoad colores similis sed major et robustior elytrisque apice late et obtuse truncatis ; cinereo-fusca, 
elytris utrinque ante medium plaga magna albo-cinerea nigro-punctata, et prope apicem litura cinerea 
multiflexuosa ; oculis lobo inferiori magno, oblongo; antennis pedibusque cinereo-fuscis ; thorace spina 
laterali tuberculiformi longe ante basin, ante spinam subrotundato-angustato, post spinam sinuato vix 
angustato ; scutello nigro bimaculato; elytris apice late parum oblique truncatis angulis nullo modo 
productis, prope basin sat confertim confuse punctulatis, apud plagam cineream et ultra versus apicem 
punctis lineatim digestis, nigris, nonnullis nigro-marginatis.

Closely allied to WV. efflicta, which has in some examples a similar slender subapical 
| grey zigzag marking, but with much finer punctuation, especially on the ashy-white 
-lateral spot. 
The three preceding species belong to the typical group of Myssodrys, distinguished
