82 MEMOIRS ON THE COLEOPTERA. 



A small but distinct species having the characteristically parallel 

 form of Metaxya. Specimens from Ithaca, New York, are very 

 similar and perhaps identical, though apparently having the anten- 

 nae a trifle shorter and the prothorax not so wide and rather less 

 asperately punctate. 



Metaxya delectans n. sp. Elongate, rather depressed, not parallel, feebly 

 shining, the micro-reticulation distinct, the punctures minute and not close- 

 set, the vestiture rather long and coarse; color piceous, the head and abdomen 

 black, the latter pale apically, the elytra moderately pale, infumate basally, 

 the legs pale piceo-flavate; head nearly as long as wide, the eyes unusually 

 large, at about their own length from the base, the tempora subparallel and 

 not as prominent as the eyes, then broadly rounded to the base, the carinae 

 distinct though far from entire; antennae long and slender, very feebly and 

 gradually incrassate, the outer joints nearly as long as wide, the last not quite 

 as long as the two preceding, the second greatly elongated and longer than 

 the third; prothorax about as long as wide, subparallel, the sides feebly, 

 rather unevenly arcuate, distinctly wider than the head and much narrower 

 than the elytra, the sides just visibly most prominent near apical third, 

 unimpressed; elytra large, very long, apparently longer than wide, nearly 

 parallel, with straight sides, very much wider and longer than the prothorax; 

 abdomen distinctly narrower than the elytra, parallel, the sixth ventral plate 

 (cf) prominent, the sides gradually and arcuately converging, the middle of 

 the apex with a small and almost semicircular emargination, the limiting 

 angles of which are sharp but not prominent; basal joint of the hind tarsi 

 very slightly longer than the second. Length 3.3 mm.; width 0.68 mm. 

 Oregon (Lane Co.). 



This very distinct species should perhaps be subgenerically sepa- 

 rated from Metaxya, but there seem to be no very radical structural 

 differences, notwithstanding the peculiarity of habitus. It is prob- 

 ably related to californica Bernh., but not closely, as the head 

 does not have an "unpunktierten Flech" at the middle, the pro- 

 thorax much smaller and narrower and the elytra much more elon- 

 gate. 



The two following species are apparently members of the Metaxya 

 group, though some of their features are not so typical as in the 

 European species: 



Metaxya plutonica n. sp. Parallel, only feebly convex, deep black, the 

 elytra scarcely visibly picescent, the legs piceous-black; vestiture fine, short, 

 dark cinereous and inconspicuous, the punctures very fine, close but not 

 asperate on the elytra; micro-reticulation distinct, finer and transversely 

 wavy on the abdomen, the lustre moderately shin ng throughout; head 

 large, transverse, rapidly widening to the base, the eyes rather small, much 

 shorter and less prominent than the tempora, the carinae wholly obsolete;
