56 MEMOIRS ON THE COLEOPTERA. 



I would prefer to use the word Echidnoglossa until it can be more 

 rigidly demonstrated that our genus is absolutely the same as the 

 Chilean, and after that it would remain to adopt a spelling conform- 

 ing to the original and not emended. The genus is very abundant 

 in species and individuals in western North America and many new 

 ones are now added to those previously known. 



Echidnoglossa aemula n. sp. Large and rather stout, shining, dark 

 rufous, the head, elytra and feeble posterior suffusion of the abdomen 

 piceous-black, the legs piceous, paler distally; head of the usual form, 

 as long as wide, the antenna? rather long, blackish, gradually paler basally, 

 with the joints slender and much elongated, especially the first three, 

 rather rapidly, moderately incrassate distally, the tenth joint not quite 

 as long as wide, the last nearly as long as the two preceding; prothorax 

 convex, slightly narrower than the head and distinctly longer than wide, 

 parallel, the sides converging to the very narrow apex in about apical 

 two-fifths; elytra large, not quite as long as wide, about four-fifths wider 

 than the prothorax and a third longer, parallel, the sides much rounding 

 inward at apex as usual, the punctures contrasting greatly with the very 

 minute anterior sculpture, being coarse and dense; abdomen relatively 

 narrow, swollen posteriorly, where it is but slightly narrower than the 

 elytra, finely, sparsely punctate, coarsely and densely so in the large 

 basal impressions of the three basal tergites. Length 3.2 mm. ; width 0.73 

 mm. California (Lake and Sta. Cruz Cos.). Abundant. 



Closely allied to valida, almost as large and of nearly like color- 

 ation and sculpture, except that the antennae are not quite so 

 long, the fine punctures of the head not uniform in density through- 

 out as in that species but much sparser toward the middle of the 

 front, that the prothorax is narrower, more elongate, paler in color 

 and narrowed to apex not from about the middle but from a point 

 distinctly in advance of the middle, and, finally, differing in its 

 longer, coarser and notably paler pubescence. Valida is still 

 represented by the unique type. 



Echidnoglossa concinna n. sp. Nearly similar to form and coloration 

 of the body but smaller in size and with paler legs, shining, the vestiture 

 long, coarse, pale and somewhat shaggy; head fully as long as wide, the 

 antennse long, slender, pale, gradually moderately incrassate and infus- 

 cate distally, the outer joints as long as wide, the last long, nearly equal 

 to the two preceding; prothorax longer than wide, relatively small, nar- 

 rower than the head, narrowed anteriorly from slightly before the middle; 

 elytra very large, formed as in the preceding, the abdomen notably 

 narrower, especially toward base but similarly sculptured. Length 2.85 

 mm.; width 0.66 mm. California (Lake Co.). Abundant.
