punctulation and pubescence ; but, in the tropical forms, the elytra 

 generally have many fine costules, with a finer geminate pair of 

 raised lines along the middle of each interval. Between the very 

 long scutellar stria and the feebly deflexed basal part of the first 

 regular stria, there is usually a series of punctures, particularly 

 developed in species of the lecontei type. The joints of the anterior 

 male tarsi are very asymmetric, the outer part being bluntly pro- 

 duced; this asymmetry is far more conspicuous than in the Pter- 

 ostichid genus Loxandrus. The pronounced isolation of Galerita 

 in morphologic type, is even more evident in the larva, as shown 

 by Salle — quoted by Lacordaire — than in any of the numerous 

 peculiarities of the imago. There is such a monotonous con- 

 sistency in form, size and coloration among the species as to have 

 led to a good deal of confusion in synonymy, the case being rather 

 like that of Brachinus in this respect ; but in reality our species are 

 far more numerous than hitherto suspected, those at present repre- 

 sented in my collection being readily separable as follows: 



Elytral surface even 2 



Elytral surface finely costulate; legs black 1 6 



2 — Legs pale ferruginous in color 3 



Legs black 14 



3 — Sides of the head behind the eyes partially parallel or very moderately 

 oblique, generally a little more oblique in the male than in the 



female 4 



Sides strongly oblique from the eyes to the base in both sexes 9 



4 — Antennae longer and very slender in both sexes, the fourth joint rather 



more than four times as long as wide 5 



Antennae much shorter, the fourth joint not four times as long as wide. . . 8 

 5 — Body more slender, the elytra about twice as long as wide in both 

 sexes. Black, the prothorax above throughout and beneath, except 

 at base, and also the legs, ferruginous, the tarsi darker; head longer 

 than wide, three-fourths as wide as the prothorax, the eyes very 

 prominent, at one-half more than their length from the base; tem- 

 pora obliquely rounded from the eyes to the base; antennae of the 

 usual coloration, the basal joint ferruginous, the next three black, 

 the remainder blackish-brown, gradually paler toward the antennal 

 tip; neck much constricted; prothorax somewhat longer than wide, 

 the parallel sides broadly and subevenly arcuate, broadly reflexed, 

 more so at base, sinuate before the basal angles, which are obtuse, 

 blunt and reflexed, the base one-half wider than the feebly sinuate 

 apex; apical angles broadly rounded and obliterated, the surface 

 feebly, subevenly convex, strongly and densely punctate and feebly 

 rugulose, the pubescence pale; surface impressed transversely at 

 base; elytra nearly twice as wide as the prothorax, parallel, the
