gissimo subcylindrico-fusiformi : lahlales (fig. Ic) articulo 

 Imo sat magno subflexuoso, 2do majore crassiore sub- 

 obtriangulari, ultimo longissimo crassiore subfusiformi. 

 Menlum breve, transversum, lateribus paulo rotiindatis, an- 

 tice profunde bisinuatiim et dente medio obtuso auctura, 

 angulis lateralibus paulo longioribus acutis. Ligula robusta, 

 cornea, e duplici parte (basali et apicali) formata ; parte 

 antica profnnde bipartita, lobis divergentibus, intus longe 

 ciliatis. Pedes longiusculi : iibiis extus simplicibus, paulo 

 incurvis : tarsis ut in Trogosild, articulo Imo brevissimo fere

Obs. Genus Temnochilce affinitate proximum et cum illo 

 speciebus sat magnis submetallicis necnon antennarum in- 

 strumentorumque cibarium structura fere congruens ; sed 

 corpore angustiore subcylindrico, antennis brevioribus, capite 

 prothoraceque longioribus, oculis antice rotundatis integris, 

 e lentibus majoribus compositis necnon a margine prothoracis 

 antico longissime remotis scutelloque nuUo a TemnochUd 

 discedit.

The three important insects for which the present genus is 

 proposed would appear to combine many of the features which 

 characterize the several acknowledged genera of the true Tro- 

 gositidce ; but they are at once distinguished (I believe) from the 

 members of them all, by their very elongate head and prothorax 

 (the former of which has the eyes rounded and entire in front, 

 and placed at an immense distance from the anterior edge of the 

 latter), by their narrow, parallel, subcylindric bodies, and by their 

 perfect freedom from scutella. In their large size and sub- 

 metallic surfaces, as well as in the structure of their oral organs 

 and antennae, they have more perhaps in common with Temnochila 

 than with any other group ; nevertheless in Temnochila the an- 

 tennae are less abbreviated, the head and prothorax are com- 

 paratively shorter, the eyes are deeply emarginate in front, and 

 composed of much finer and more depressed lenses, the scutellum 

 is distinct, and the whole body is less narrow and cylindrical. 

 From Aiindria, of Erichson (judging from the published diag- 

 nosis), Leipaspis is at once removed, apart from all other differ- 

 ences, by its very much longer head and prothorax, and by its 

 simple tibiae ; whilst from Melambia, its anteriorly bisinuated 

 mentum, comparatively convex, submetallic, escutellate body, 

 and its greatly elongated head and prothorax will, even of them-
