armed with a minute tooth on inner margin at apex. Posterior tarsi 

 about one-half as long as the tibiae, and the first joint as long as the 

 following two joints united. Tarsal claws similar on all feet, cleft 

 near middle, the teeth slender, and the inner ones slightly shorter than 

 outer ones, turned inward, and their tips nearly touching. 



Length, 8.5 mm. ; width, 2 mm.

AGRILUS SESOSTRIS, new species 



Female. — Elongate, slender, feebly shining, and slightly flattened 

 above; head aeneous; pronotum purplish red; elytra black, with a 

 vague greenish reflection, subopaque, and each elytron ornamented 

 with a longitudinal pubescent vitta; beneath aeneo-cupreous, and 

 strongly shining. 



• Head with the front rather wide, feebly convex, distinctly nar- 

 rower at top than bottom, the lateral margins feebly arcuately ex- 

 panded at middle and obliquely expanded at bottom, and with a 

 broad, shallow depression on the vertex; surface densely, finely 

 granulose, sparsely punctate, coarsely irregularly rugose, and sparsely 

 clothed with semierect white hairs behind the epistoma; epistoma 

 slightly transverse between the antennae, and broadly, arcuately 

 emarginate in front ; antennae extending to middle of pronotum, ser- 

 rate from the fourth joint, and the outer joints as wide as long; eyes 

 moderately large, broadly oblong, and slightly more acutely rounded 

 beneath than above. 



Pronotum slightly wider than long, about equal in width at apex 

 and base, and widest at apical third; sides feebly arcuately rounded 

 from apical angles to behind middle, then parallel to the posterior 

 angles, which are rectangular; when viewed from the side the mar- 

 ginal and submarginal carinae are feebly sinuate, narrowly sepa- 

 rated anteriorly, and connected to each other behind the middle; 

 anterior margin strongly sinuate, the median lobe strongly produced, 

 and broadly rounded; base broadly, arcuately emarginate at middle 

 of each elytron, the median lobe feebly produced, and subtruncate 

 in front of scutellum ; disk with a very shallow, broad, median 

 depression in front of middle, very broadly, obsoletely transversely 

 depressed behind the middle, a broad, deep depression on each side 

 along lateral margin extending from apical angle to base, and with 

 strongly elevated, straight prehumeral carinae extending from pos- 

 terior angles to middle, but not connected to the marginal carinae; 

 surface rather coarsely, closely, irregularly rugose, finely, sparsely 

 punctate between the rugae, and densely clothed with recumbent
