will not agree in all respects ; like Amblygnathus, it has no tooth 

 to the mentum, and the antennae short, but the eyes must be more 

 prominent. The tarsi are short. 



Family BembidiidtE. 



Notaphus galapagoensis. Not. seneus, nitidus, antennis nigrescen- 

 tibus, ad basin, pedibusque testaceis ; thorace transverso, postice 

 utrinque fovea oblonga impressa, lineaque longitudinali elevata 

 notato ; elytris punctate- striatis, fasciis duabus arcuatis, rufescen- 

 tibus, ornatis. — Long. corp. 1^ lin. 



Body rather short and broad. Thorax broad and transverse, mo- 

 derately convex, the sides boldly rounded and but slightly sinuated 

 near the posterior angles, which are nearly right angles ; dorsal 

 channel distinct, and continued from the base to the apex of the 

 thorax ; a narrow oblong fovea is situated on each side behind, 

 rather nearer the lateral margin, or angle, than the mesial line, and 

 extending from the angle is a ritlge which is about one-third of the 

 length of the thorax and parallel with the mesial line, and hence, 

 although the ridge springs from the angle, it is somewhat remote 

 from the lateral margin at its apex, — the margin being bowed out- 

 wards ; the disc of the thorax is smooth, but the lateral and poste- 

 rior margins are coriaceous. The elytra are rather broad, of a 

 brownish seneous hue, distinctly punctate-striated ; rather in front 

 of the middle is an irregular, transverse, yellowish band, which is 

 subinterrupted in parts, and does not extend to the suture ; it de- 

 scends obliquely downwards as it runs in from the outer margin, 

 where it is met by a humeral pale mark : there is a faint trace of 

 two pale spots above this band : about the hinder third of each 

 elytron is a curved mark which commences on the second inter- 

 stice from the suture, runs outwards to the margin, and forming 

 a segment of a circle, extends to the apex of the elytra. A largeish 

 depression is observed on the third interstice from the suture on 

 the anterior third of each elytron. The whole of the basal joint, 

 and the base of the second, third and fourth joints of the antennae 

 are yellow; the rest of the joints are blackish. 



This species is from James^ Island.

Copelatus (?) galapagoensis. Cop. ovatus, parum convexus, piceus ; 

 capite, marginibus lateralibus thoracis et elytrorum, antennis pe-
