418 THE CANADIAN ENTOMOLOGIST. 



bisiniiate yellow side margin, which is continuous throughout, though 

 retreating from the edge posteriorly, not quite attaining the suture ; under 

 surface feebly and rather sparsely punctate, the anterior legs pallescent. 

 Length, 1.8 mm.; width, 1.15 mm. Arizona (Nogales), Nunenmacher. 



Belongs near Hmbalis, the ornamentation being almost identical, 

 though more closely approaching the suture at apex, but differing greatly 

 in the narrower, more elongate and parallel and much less oval form of 

 body, and also in the sparser and very much feebler punctuation of the 

 under surface. Spicuimoia, Fall, belongs to the 4-oculata series, as do 

 also the two following : 



H. fidelis, n. sp. — Form slightly more broadly oval, convex, polished, 

 black ; head black ( $ ), the pronotum with a similar lateral pale margin ; 

 elytra similarly rather strongly punctate, with a narrow pale lateral border, 

 which is feebly and broadly sinuate within, in basal two-thirds, a large 

 subtriangular subapical spot and a discal spot twice as long as wide, the 

 centre of which is only very slightly before the middle ; under surface 

 black, the abdomen finely, sparsely punctate, the legs all pale red-brown, 

 the metacoxal plate not quite attaining the apex of the segment, which it 

 fully attains in 4-oculata. Length, 2.3 mm.; width, 1.6 mm. California 

 (Los Angeles). 



H. Bensonica, n. sp. — Still more broadly oval and a little more convex, 

 polished, black ; head pale, except at the basal margin ( ^ ), the pronotum 

 with narrow parallel pale sides ; elytra sparsely but strongly punctate, 

 with a narrow yellow lateral border, which is strongly sinuated within and 

 extending from the base to apical third, a transversely oval subapical spot 

 and a circular discal spot at basal two-fifths, much in advance of the spot 

 in 4-oculaia or notatida; abdomen more closely and strongly punctate, 

 the legs blackish, except the anterior, the metacoxal plate about attaining 

 the segmental apex. Length, 2.0 mm.: width, 1.5 mm. Arizona (Benson), 

 Nunenmacher. 



In the true 4-oadata^ from the middle California coast regions, there 

 is normally no yellow elytral margin or spots, but occasionally there are 

 two very feeble elongate streaks, at base and behind the middle. The 

 male has the black base of the front deeply angulate, while in the male of 

 7iotaiiila the black at the base is transversely truncate, except at the sides, 

 where the pale area extends further posteriorly along the eyes, in a way 

 just the reverse of 4-oculata. Horni, of Crotch, would appear to be 

 different from 4-oculata and not identical, as I suggested in my Revision,
