306 THE CANADIAN ENTOMOLOGIST. 



Channels of spring runs on hills dry in summer ; not common, but 

 abundant when found. This has been distributed as a variety of reflexus, 

 Lee, from which it is very distinct, the latter being much larger, with a 

 more elongate and differently shaped thorax, tripunctate elytra, and 

 piceous underside and legs. P. cinctus has the same form of thorax with 

 parmarginatus, but the reflexed margin of the thorax is much narrower 

 anteriorly than posteriorly; the thorax of reflexus is perceptibly longer, a 

 little coarctate on the sides before base, widest one-third from apex, and 

 may be termed lyriform. 



Stenelophus humidus. — Piceous black, shining, basal joint of antennae 

 and feet pale. Head short, two-thirds as wide as thorax, smooth, 

 antennae brown except basal joint, very pilose ; thorax quadrate, a little 

 narrowed behind, sides curved, basal angles rounded, scarcely obtuse, 

 impunctate, discal line fine, sometimes obsolete, basal impressions shallow, 

 impunctate, often with minute rugae, lateral edge narrowly ferrugineous ; 

 elytra with impunctate striae, intervals scarcely convex, the third with a 

 minute puncture at apical third, somewhat iridescent, extreme suturaland 

 marginal edge sometimes pale ; scutellar striae at most rudimentary, fre- 

 quently invisible ; in the $ , middle and anterior tarsi have the fourth 

 joints deeply bilobed. Length, .J8-.20 inch. Characterized from 15 

 examples. Habitat: Grassy swampy places in meadows and about 

 springs. Abundant. Distinct from 5". plebeius, which it closest resem- 

 bles, by its smaller size, less rounded thorax, obsolete scutellar striae, and 

 other characters seen on comparison. This species has been distributed 

 as Stenelophus, N. S. 



Soronia substriata. — Oval, length twice the width, much depressed, 

 pubescent, sordid, rufescent. 



Head finely punctulate, a transverse row of minute tubercles and some 

 scattering ones, antennae brown, fourth joint scarcely shorter than third, 

 antennal grooves nearly parallel ; thorax two and one-half times wider 

 than long, apex deeply emarginate, base truncate, sides regularly curved, 

 incurved a little at base, side margins widely explanate and moderately 

 reflexed, medial line indistinct, surface not indented, densely finely punc- 

 tured to the extreme margin, pubescence fine and matted together on the 

 disk with a brown indument producing a granulated appearance; elytra 

 widest at the base, sides forming with those of the thorax, except the 

 sinuation at base, a regular oval curve and with continuous broad reflexed 

 margins, feebly costate or substriate, densely finely punctured, setose,
