2G0 GEO. n. noRN, m. d. 



finely not densely punctulate, with feeble strigosity near the margin. Elytra 

 not wider than the thorax, about one and a half times longer than wide, sides 

 feebly arcuate and gradually narrowed to apex, sutural stria moderately 

 impressed, disc obsoletely substriate, surface very finely and densely trans- 

 versely strigose. Body beneath and femora moderately densely punctulate. 

 Length .14 inch; 3.5 mm. 



The lower edge of the femora is acute near the base, slightly 

 grooved and smooth externally. The anterior tibia? of the male are 

 simple, not sinuate, the tarsi moderately dilated, the first joint of 

 middle tarsi moderately thickened. The ventral segments are simple 

 in both sexes. 



This species has some resemblance to Ftom. nevadlcus as well as to 

 luridipennis of the present genus, but it is readily recognized by its 

 strigose elytra, a character otherwise unknown in the genus. 



Occurs at Olympia, Washington Territory, (Morrison). 



C. terininans Lee. (Catops). — Oblong-oval, pieeous or brownish, pubes- 

 cent, margins of thorax and elytra continuous. Head moderately densely 

 punctulate. Antennae pieeous, apical and two basal joints paler. Thorax twice 

 as wide at base as long, sides arcuate and narrowed to the front, apical angles 

 obtuse, basal angles rectangular but not produced, base truncate, surface 

 densely finely punctulate. Elytra as wide at base as the thorax, gradually 

 arcuately narrowing to the apex, sutural stria moderately deeply impressed, 

 surface not very densely punctate. Body beneath- moderately densely punctu- 

 late. Length .10 — .12 inchj 2.5 — 3 mm. 



The lower edge of the anterior femora is flat and curved in its 

 entire length without trace of tubercle in the male. The males have 

 the anterior tibiae stouter than in the female and more suddenly 

 narrowed at base, the tarsi are also moderately dilated, the first joint 

 of middle tarsi proportionately stouter than in any other species. 

 The abdomen is not impressed in either sex. 



The form of the hind angles is peculiar to this species in the 

 present genus and a relationship to Ftomapliagus indicated. 



Occurs from Canada to Massachusetts, Virginia and Illinois. 



PRIONOCH.ETA n. g. 



Form elongate-oval, moderately convex. Head suddenly narrowed behind 

 the eyes, occiput elevated received against the apex of the thorax. Eyes oval, 

 flattened posteriorly. Antennse as long as the head and thorax, feebly thick- 

 ened externally, last four joints rather abruptly shorter than the preceding, 

 the eighth shorter and very little narrower than the ninth. Last joint of 

 maxillary palpi elongate conical, acute at tip, equal to the third joint. Middle 

 coxse contiguous, mesosternum flat. Hind coxae contiguous. Tarsi slender, the 

 anterior dilated in the male, first joint of the posterior nearly equal to the 

 others united. Spurs of middle and hind tibise long, the inner nearly equal to 

 the first joint of the tarsi, the spurs of all the tibiae pectinate on both margins
