BEMBIDIIN^E 45 



flexed, the impressions subobsolete, the stria moderately impressed, 

 not entire; foveae narrow and very deep, the carina strong; elytra 

 one-half longer than wide or less, nearly one-half wider than the 

 prothorax, strongly rounded behind, having very feebly glimpsible 

 traces of two or three sutural striae, the foveae before basal and at 

 apical third. Length 3^35 mm.; width 1.2 mm. California (one 

 typical example from an unrecorded locality; also one taken by the 

 writer at Lake Tahoe, agreeing well but with more obtusely rounded 



elytra horni Hay w. 



Prothorax distinctly narrower at base than at apex 4 



4 Form and size nearly as in the preceding, polished, smooth and nearly 

 black, the epipleura and legs flavate, each elytron with a flavate 

 spot behind the humeri, extending inward beyond the middle, its 

 base on the margin extending to the humeri and, at apical third, a 

 transverse fascia, not quite extending to the suture; the reflexed 

 margins are also paler piceous; head fully five-sixths as wide as the 

 prothorax, the antennae somewhat longer than the elytra, piceous, 

 becoming flavate basally, the medial joints not quite three times as 

 long as wide; prothorax much narrower, only a fifth wider than 

 long, the sides but very finely reflexed, strongly rounded anteriorly, 

 oblique and sinuate behind, becoming parallel in basal sixth, the 

 hind angles right and very sharp; surface convex, the stria fine, not 

 entire, the foveae very deep and adjoining the fine carina; elytra 

 one-half longer than wide and two-thirds to three-fourths wider 

 than the prothorax, rather sharply ogival in apical two-fifths; the 

 only striae evident, though feeble, are the first and second toward 

 tip, the eighth well impressed and entire; foveae at basal and apical 

 fourth. Length (c? 1 9 ) 3.0-3.5 mm.; width 1.15-1.3 mm. Cali- 

 fornia (Sta. Barbara to Humboldt) and Nevada (Reno). Abun- 

 dant; twenty-three examples. [Ochthedromus mnndiis Lee.]. 



bifasciatum Mots. 



Form and coloration nearly as in bifasciatitm but very much larger, and 

 with the longer antennae flavate throughout, blackish, with bluish 

 lustre anteriorly, the elytra pale castaneous, each with two flavate 

 spots very nearly like those of bifasciatum; epipleura and legs flavo- 

 testaceous; head four-fifths as wide as the prothorax, the sulci rather 

 broad but deep; antennae very slender, filiform, fully as long as the 

 elytra, the medial joints nearly four times as long as wide; prothorax 

 fully a third wider than long, the sides rather finely reflexed, evenly 

 rounded from apex to near basal fifth, where they become rapidly 

 sinuate and thence parallel for a very short distance before the angles, 

 which are rather sharp, though somewhat more than right; surface 

 nearly as in the preceding, except that the basal foveae are relatively 

 not so large or deep; elytra longer and more oval, parallel, with dis- 

 tinctly arcuate sides, three-fifths longer than wide and three-fourths 

 wider than the prothorax, not so narrowly rounded in about apical 

 third, the striation subsimilar, the foveae three in number, situated 

 before basal and behind apical fifth and at the middle. Length (9 ) 

 4.0 mm.; width 1.6 mm. California (Sta. Barbara). Mr. Dunn.
