eye the head does appear wider than the thorax, though by 

 measurement it is not actually so. " Four teeth of the clypeus 

 of equal size " — in the specimen before me this is not the case; 

 the outer pair of teeth are prominent and triangular, the inner 

 pair merely obtuse prominences. " Prothorax much longer than 

 broad '"' — it appears so to the eye, but is only slightly longer b}'' 

 measurement. 



Teratidium frenchi, n.sp. 



Elongate, Isevigate. Head large, constricted posteriorly ; pro- 

 thorax hardly longer than broad, strongly angustate to base, 

 marginal channel unipunctate about half-way between anterior 

 and posterior angle; elytra long, impunctate, lateral border thick 

 — particularly posteriori}'; anterior tibiae unidentate. Head 

 black with green tinge on neck (above and below) and beneath 

 eyes ; prothorax green, brighter towards sides, under surface 

 green, brighter on episterna; elytra green; body and legs black 

 with greenish reflections on sides of mesosternum and of ventral 

 segments. 



Head la^vigate, convex ; anterior part widely subquadrate, 

 defined posteriorly 1)}^ a transverse impression; front with a light 

 oblique linear impression on each side defining sides of clypeus, 

 a punctiform impression at internal extremity of each of these 

 sulci; clypeus impunctate, convex, strongly declivous to anterior 

 margin, median part lightly produced in middle — this median 

 prominence wide and very lightly emarginate — intermediate 

 angles rather prominent, obtuse, wide at base; supra-antennal 

 plates large, convex, rounded externally; eyes deeply set in 

 orbits, rather prominent; orbits large, enclosing posterior two- 

 thirds of eyes, obliquely and roundly narrowed to neck; one 

 supraorbital puncture on each side. Prothorax of same width as 

 head, hardly longer than broad (5-6 x 5 5 mm.), convex, declivous 

 posteriorly to the wide basal area between juxtabasal sinuosities 

 of border; sides subparallel in middle, lightly narrowed to anterior 

 angles; posterior angles not marked; apex truncate, anterior 

 angles feebly advanced; base widely and evenly rounded between 

 juxtabasal sinuosities^ border narrow, even, a little wider at
