The only structural difference between this species and D. furcula is in the less 
prolonged apices of the elytra, which also are less close together, owing to the less 
oblique truncature, which leaves plainly visible the marked sutural angle. To this 
peculiarity, however, is added one of elytral markings, D. lignea having always a long 
arcuated cinereous spot in the middle of each side, of which there is scarcely any trace 
in D. furcula.” The dark brown circumscutellar spot is in both rather short and. 
quadrate, and bordered externally by a very broad ashy-white vitta, which curves from 
the shoulders to the suture. In both species the upper lobe of the eyes is very narrow, 
scarcely broader than the narrow band which connects it with the lower lobe. The 
ciliee of the antenne are very short and less dense than in D. Oryx. 
2 (s). Dorcasta mexicana. | 
D. furcule et D. ligne affinis, sed differt macula atro-fusca circumscutellari triangulari extus vitta angusta 
recta et obliqua marginata. Fulvo-fusca, thorace (antice convexo) vittis duabus angustis dorsalibus nigris 
et utrinque vitta laterali angusta albo-cinerea ; elytris fulvo-fuscis, macula magna circumscutellari vittaque 
lata curvata (plus minusve élongata) dorsali, nigris; vitta obliqua utrinque juxta maculam circumscutel- 
larem, maculaque angusta laterali intus arcuata et apud marginem maculam nigram includente, cinereis ; 
postice versus suturam guttis utrinque una vel duabus nigris interdum vittula cinerea connexis ; thorace 
crebre, elytris lineatim, punctatis, his apice sinuatim oblique truncatis angulo exteriori plus minusve - 
prolongato ; antennis et oculis sicut in D. lignea.

4. Dorcasta obtusa. (Tab. XXIII. fig. 1.) 
D. geometric quoad signaturas simillima, sed valde differt elytris apice obtuse rotundatis. Cylindrica, postice 
haud angustata, fusca ; thorace parum convexo, vittis duabus utrinque lateralibus albo-cinereis, dorso vittis 
nigris tribus antice convergentibus et marginem anticum attingentibus ; elytris apice -citius declivfbus, 
macula magna semiovata circumscutellari (postice albo-cinerea marginata) figuraque pone medium X- 
formi, communibus, atro-fuscis, interspatiis et apice pallidius fuscis albo-cinereo lituratis ; antennis filifor- 
mibus, crassis, obscure fuscis, subtus dense breviter ciliatis.
