procliiced, bri);ully truncate, the convergjiiig sides before the eyes 

 rather strons^ly arcuate; prothorax about two and a third times as 

 wide as lt)iig;, otherwise as in injlatus and qmite as densely sculp- 

 tured 'throughout ; elytra fully a fourth longer than wide, more 

 than three times as long as the prothorax and but slightly though 

 evidently wider, unusually acutely and gradually ogival at tip, 

 the sides feebly arcuate, rounding as usual at base, the punctures 

 fine, irregular and well separated but more strongly muricate than 

 usual, becoming more closely aggregated into obscure longitudinal 

 and very faintly elevated lines laterally, the pleural imjiression 

 subobsolete; abdominal segments narrowly margined with black 

 at apex, the impressions of the third segment in the female very 

 faint and subobsolete. Length 6.5 mm. ; width 3. 28 mm. Cali- 

 fornia curvipes n. sp. 



It is assumed that the small impressions subequally trisecting 

 the width of the third abdominal segment at apex, visible in 

 some individuals, pertain to the female, for the reason that my 

 only specimen having the intromittent spicule protruded is 

 devoid of these impressions. Of ovifonnis I have a very large 

 series, exhibiting but little variability, and, although the species 

 adhere closely to a common type of structure throughout, I am 

 therefore somewhat confident of their validity as expressed 

 above. 



Emmenides n. gen. 

 In general facies this genus is not unremindful of Meto^oniiim^ 

 but with the fine sculpture of Tclabis. The frontal margin is 

 entire and very broadly arcuato-truncate, the mandibles feebly 

 cleft at tip, flat above, with a broad flat ridge externally at base, 

 and the mentum has the usual small apical emargination. 

 The antennae are long and slender, the eyes rather large and 

 notably prominent, the scutellum short but distinct and strongly 

 transverse, and the hind tarsi are shorter than the tibiae, with 

 the basal joint much longer than the last. The single species 

 is the following : — 



Body oblong, parallel, convex, glabrous, shining, rather pale rufo- 

 castaneous throughout, the legs concolorous ; head broad, not 

 very coarsely but deeply and closely punctate, the sides much 

 less prominent than the eyes, strongly converging and arcuate, 

 merging gradually into the apical margin ; prothorax three-fourths 

 wider than long, much narrower at ajoex than at base, the sides 

 evenly converging throughout and broadly, evenly arcuate, the 

 apex sinuate, the angles right, not rounded, the side margins
