46 MEMOIRS ON THE COLEOPTERA 



feebly rugose; antennae (cf 1 ) stout, about half as long as the body, or 

 ( 9 ) shorter, two-fifths as long as the body; prothorax nearly three-fifths 

 wider than long, the sides strongly rounded anteriorly, converging and 

 becoming strongly sinuate basally, the angles sharp, generally less than 

 right and somewhat everted, the sides narrowly but distinctly reflexed, 

 strongly so basally, the anterior impression feeble and sparsely punctate, 

 the basal deep and a little less sparsely punctate, the impressions near 

 the angles very deep and conspicuous; median line strongly impressed; 

 elytra two-thirds (c?) to three-fourths (9) longer than wide, the base 

 much wider than any part of the prothorax, widest near apical third 

 (c? 1 ), or nearly parallel (9), the sides broadly arcuate; humeri distinct 

 though rounded; striae broadly impressed, very obsoletely and irregularly 

 punctate, the intervals strongly convex, generally somewhat alutaceous; 

 legs uniform in color throughout, brownish-black. Length 9.0-10.4 mm. ; 

 width 3.6-3.9 mm. Labrador (West St. Modest), John Sherman. 



The large foveae of the elytra exhibit the most astonishing diversity 

 among the three males and two females sent to me by Mr. Sherman 

 and one female the type has the outer half of each elytron 

 reddish-brown; in all the examples the lateral margin is greenish 

 in lustre. In the type example the third interval has about four 

 foveae on each elytron, the fifth two on the right elytron but none on 

 the left. In the second female the third interval has three foveae 

 on the right, five on the left, the other intervals not foveate. In 

 the first male each elytron has only three or four foveae on the third 

 interval; in the second, the third interval of each elytron has about 

 three foveae, the right without other foveae but the left with a single 

 large fovea on the fifth interval and slightly before the middle. In 

 the third male, the third interval of each elytron has four or five 

 foveae, the fifth interval of the right two, of the left four. The foveae 

 are so large as to interrupt the intervals in all except the second 

 female, where they are not on the interval but rather in the sulcus 

 between the third and fourth intervals, partially extending across 

 but not interrupting the third. In all other respects these speci- 

 mens, which came to me under the names ulkei and rudis, are so 

 perfectly similar that it appears impossible that there should be 

 more than one species. It is a rather remarkable case of instability 

 but affects the elytra only. 



Notiophilus Dumeril. 



The two following species have been in my collection for many 

 years and, so far as it is possible to discover, have not been described 

 hitherto.
