Crjrptobium detectum sp. nov. 

 PI. XII., Fig. 2. 



A single elytron, fully two and a third times longer than broad, 

 broadest in the middle, the posterior margin squarely truncate but the 

 inner apical angle obtusangulate, the surface very profusely and very 

 delicately punctate, seems to be a Oryptobium, not very closely allied to 

 G. pallipes Grav.; compared with which it has much more delicate, denser 

 and less deeply impressed punctuation, and a relatively slenderer form. 

 The single specimen is a little imperfect, a piece having gone from the 

 outer apical angle, and the humerus is thrust forward with unusual pro- 

 minence. Length, 2-6'°°'; breadth, l-l™. 



One specimen : No. 16877, Scarborough. 



G. pallipes is found in Canada and the northern United States from 

 New England to Wisconsin, but also in Florida and Louisiana. 



Oryptobium cinctum sp. nov. 

 PI. XII., Fig. 3. 



Another species of Oryptobium is represented by a couple of elytra 

 from difierent localities, which seem to be nearly allied to C. calijornicum 

 LeO. They are scarcely more than twice as long as broad, castaneo- 

 piceous, slightly broader a little beyond the middle than elsewhere, the 

 posterior margin faintly excavate, the inner apical angle feebly produced, 

 and the surface coarsely and profusely punctate. Compared with the 

 modern species mentioned, they are a little larger and broader, and the 

 punctuation is hardly so sharp or so deep. Length, a-i"™ ; breadth, 

 MS"™. 



Two specimens : No. 16878, Logan's brickyard, Toronto ; and No. 

 16879, Scarborough. 



G. ccdifornicum comes from Nevada, California, Oregon and Vancouver 

 Island. 



Latbrobium antiquatum sp. nov. 



PI. XI., Fig. 5. 



A single elytron less than twice as long as broad, with the inner base 

 cut to indicate a broad and short scutellum, seems to belong to Latbro- 

 bium, and may best be compared with L. divisv/m LeC. It broadens 

 regularly though but slightly, has a very broadly rounded apical margin, 

 and the surface profusely and rather minutely punctate. It lacks the 

 distinct marginatipn of the sutural border seen in L. diviaum, with which
