72 OTIORHY:jfCHID^. 



[Horn. 



iug broader as it passes posteriori}', wliere it is bouuded in front and behind 

 by a line of darker scales. I have two specimens before me of an entirely 

 uniform pale-brown color. 

 Occurs in Canada and New York. 



G. incomptus, n. sp.* 



This species so closely resembles melanothrix in form, size and color 

 that it is unnecessary to .add any description. It differs only in the 

 characters given in the short table, so that if the description of melanothrix 

 be repeated with those changes only, it will equally apply to this one. 



Occurs from San Francisco to Vancouver. 



ARAGNOMUS n. g. 



Rostrum shorter than the head, broader than long, flattened above, a 

 feeble transverse impression at base, tip feebly emarginate and with a 

 smooth crcscentic space limited behind by a curved line. Scrobes sub- 

 lateral, not convergent above, cavernous, nearly attaining the eyes. An- 

 tenme scaly, moderate ; scape slightl}' arcuate, barely attaining the margin 

 of the tliorax ; funicle 7-jointed, nearly one-third longer than the scape, 

 lirst joint nearly equal to the two following, joints 3-7 obconical, gradually 

 decreasing in length ; club oval. Eyes rather small, round, not prominent. 

 Thorax cylindrical, sides feebly arcuate at middle only. Scutellum invisi- 

 ble. Elytra oval. Intercoxal process broad, truncate. Second segment 

 of abdomen as long as the two following, separated from the first by an 

 arcuate suture. Anterior tibise feebly mucronate. Claws connate. 



This insect recalls in smaller size P<u'(iptochits sellatus with less broad 

 elytra. The eyes are more distant from the thoracic mai-gin than is seen 

 in any of the other genera of the group, and the head and rostrum rather 

 large when compared with the thorax. Prom Seidlitz's table this genus 

 appears to occupy a doubtful position. The frontal impression is sufficiently 

 distinct to ally it to Soiobius, etc., but the structure of the abdomen will 

 not warrant such position. The scrobes ai'e moreover in such position tliat 

 it is impossible to say whether they should be called superior or lateral. 

 They are by no means lateral in the manner of TraG7i,i/p7do3us nad Licheno- 

 phagus. 



A. griseus, n. sp. 



Form oval, robust, surface densely covered with cinereous scales, with 

 sparsely placed, erect, black setae, longer on the elytra. Head and ros- 

 trum longer than the thorax, a slight frontal line, surface sparsely and 

 deeply punctured, densely scaly, and with short erect hairs. Thorax 

 slightly broader than long, cylindrical, truncate at apex and base, sides 

 suddenly arcuate at middle, disc moderately convex, coarsely and regularly 



* No description of this species has until now appeared. I adopt the 

 specific name by whicli it is known in our cabinets. Mention of the species 

 first occurs in a catalogue of insects collected on the survey of the Pacif. R. R. 

 ■where it is called Trachyplmus. See Pacif. R. R. Rep., App, 1, p. 21.
