3. T. angustiis sp. n. (Plate VI, fig. 4, 4a). — Cephalo-dorsal outline as shown 

 plate ix, tig. 24. Allied to ornatiis ; stature slender, eyes prominent, subglobose. 

 Head swollen about the eyes, muffled, but slightly, by the pronotum; vertex 

 broader than an eye. subexcised a trifle in front of eyes, front margin approxi- 

 mately rec.tanguhir with sides of crown, the latter depressed on forward half, 

 middle of vertex slightly carinated, barely produced ; frontal costa behind an- 

 tennsB rounded, advanced normally nearly as far as vertex, excavate sparingly 

 opposite eyes; ocelli usually visible in profile at margin of deepest point; pro- 

 notum anteriorly truncate, slender, subtectiform ; dorsum in front above articu- 

 lation of first leg but slightly constricted, median carina slight, anterior marginal 

 carina subparallel, short, separated hardly wider than vertex ; lobes small, lower 

 margin strongly oblicjue, inferior angle in profile subc.onvexed below, sides of 

 pronotum gently converging as far as knee of hind femora, apical process thin, 

 extended far backwards, nearly same thickness throughout, terminating rather 

 acutely, not reaching the end of wings. Legs thin under margin of first, and 

 both margins of second femur indistinctly scalloped : dorsum of pronotum nearly 

 horizontal, surface granulated, but not as smoothly as in ornatus or (traniilatuii. 

 Elytra oblong, surface punctate; face smooth ; carinai of the entire body reduced 

 generally. Length of body 9) 14 mm. : '^ . 12 mm. ; pronotum J- 1~ nim. ; % .

Abbreviated variety. J. — Apical process of pronotum slightly passing liind 

 knee, not quite reaching end of wings; lobes of pronotum short, inferior angle 

 strongly projecting laterally, obtusely pointed, sinus immediately above deep. 

 Length of body 10 mm.

4. T. inflsitus sj). n. (Plate VII, fig. 8). — Cephalo dorsal outline as shown 

 jdate ix, fig. 26. Similar to T. nugustus ; stature more robust, eyes less globose 

 and smaller. Head oblique, strongly muffled by the front antero-lateral margin 

 of the pronotum; vertex a little wider in front, perceptibly l>roader behind, not 

 excised as abruptly, projecting more in front of the eyes, carina of vertex hardly 

 distinguishable, barely showing in front ; in ])rofile the frontal costa is more 

 deeply and sharply exc«.vate opposite the eyes almost to their front outline ; 

 pronotum broader, compact in front, anterior carina oblique, distance apart at the 

 anterior dorsal margin considerably more than the front margin of vertex ; dorsal 

 surface between angles of lateral margin slightly swollen, immediately behind 

 subdepressed, sloping gently backwards to process; median carina thin, almost 

 obscure, apical process larger, concaved, not reaching end of wings; lobes larger, 

 more turned out at the inferior margin ; lateral carina', in their front eoui-se 

 sharply accentuated. Legs strong, anterior femora compressed, slightly carinated 

 below, second femur subspatulate, distinctly carinated, both margins roughly 

 scalloped ; surface of dorsum tul)erculate and granulated. Elytra elongate, 

 punctate, sometimes slightly granulate. Length of body 9i l~-5 mm.; '^,11 

 mm.; i)ronotum 9,12 mm.; '^,10 mm.; hind femora 9'*»'i""-; 'E . » mm.
