THE CANADIAN ENTOMOLOGIST 165 



Casey, in which the eyes, though not lacking, are very small. The 

 species is with pleasure dcfiicated to its disco\'erer. 

 Tribalister striatellus, n. sp. 



Rotundate ovsd, castaneous, moderately shining; above 

 minutely, sparsely, evenly puhctulate; elytra 6-striate, the four 

 outer ones subentire, the two inner abbreviated at base; sutural 

 stria punctate, the others scarcely so except near the apex; margin of 

 elytra acute and continuous with that of the prothorax; discal 

 striae entirely without cariniform outer margins. Propygidium 

 coarsely, densely punctate, smoother narrowly along the base; 

 pygidium more finely, sparsely punctate, with intermixed still 

 finer punctures, the latter alone present at apex. Sides of body 

 beneath very coarsely, densely punctate. Otherwise in nearly all 

 respects as in 7". marginelliis. Length 2 mm.; width 1.5 mm. 



Rhode Island, Berkley'; a single example taken by the writer 

 many years ago under a stone in early spring. It was then identi- 

 fied as probably T. marginelliis, by Mr. Frederick Blanchard, but 

 a recent comparison with the type of the latter inclines me to the 

 belief that it is specifically distinct. In marginelliis the upper sur- 

 face is virtually impunctate e.xcept for the coarse punctures along 

 the elytra! apex (which are also present in striatellus) ; the so-called 

 elytral striae, after the second, which is very finely impressed, are 

 really not striae at all, but costae, the striae being completely obsolete 

 and traceable only by the slightly different surface lustre along the 

 inner side of the costje; the sutural stria is impunctate, the pygidium 

 is less finely punctate, and the sides of the body beneath are less 

 coarsely and densely so. The region between the hind coxae, in- 

 volving the apical portion of the metasternum and the basal part 

 of the first ventral segment is broadly depressed — not at all so in 

 striatellus. The frontal stria is interrupted medially in marginelliis, 

 finely impressed and entire in striatellus. MargineUus was described 

 in 1859, the type being from Maryland, and very few examples 

 have since been taken. Striatellus also appears to be excessively 

 rare, and I am not aware that a duplicate exists in collections.
