ture, with relation to the recurved portion of the sutural stria, that 

 is whether or not it is enclosed within it, will indicate to which 

 group the species should be referred. This is shown on Plate VI, 

 figs. 7 and 8. 



Our species are moderately numerous, and several resemble each 

 other very closely. The following table, it is hoped, will assist in 

 their determination : 



Eyes large, prominent 2. 



Eyes smaller, less convex ; pale yellowish-testaceous ; thorax distinctly narrower 

 at base than apex : elytra scarcely wider than the thorax, feebly or 

 obsoletely striate. Length .08. 10 inch liioruax Lee. 



2. Thorax squarely truncate at base ; legs pale 3. 



Thorax more or less obliquely truncate each side at bast 5. 



3. Thorax slightly narrower at base than apex 4. 



Thorax very distinctly narrower at base than apex ; head nearly black, thorax 



piceous or rufopiceous, elytra pale testaceous, with the suture slightly 

 infuscate: form very elongate, subparallel ; elytra scarcely wider than 

 the thorax, which is slightly wider than long. Length .09-. 10 inch 



Virgo Lee. 



4. Less elongate; pale rufotestaceous, the head and thorax scarcely darker; 



elytra slightly wider than the thorax, which is about one-half wider 

 than long. Length .09-11 inch pallida* Chaud. 



Piceous or black, the elytra slightly wider than the thorax, with either a vitta 

 varying in breadth and extending nearly to apex, or a subhumeral 

 spot pale, or even entirely black ; thorax with the sides slightly sinu- 

 ate behind, hind angles rectangular. Length .09-. 12 inch. 



vittiger Lee. 



More robust ; color varying from brownish to nearly black, the elytra often with 

 a subhumeral and sometimes a subapical spot pale, the two rarely 

 united to form a longitudinal vitta; elytra one-half wider than the 

 thorax, which has the sides sinuate behind and the hind angles rec- 

 tangular. Length .09. 12 inch occullator Casey. 



5. Slightly broader than vittiger ; color dark piceous or black, the elytra some- 



times with a pale longitudiual vitta; thorax slightly narrower at base 

 than apex, sides not sinuate behind, hind angles obtuse, but not 

 rounded ; elytra distinctly wider than the thorax ; femora piceous or 

 black, tibipe and tarsi paler. Length .08-. 10 inch corax Lee. 



More elongate; color black; thorax more narrowed behind, sinuate in front 

 of the hind angles, which are subrectangular ; elytra scarcely wider 

 than the thorax ; legs pale. Length .09 inch misellus Laf. 



Broader; color piceous, the elytra with the sutural region, especially towards 

 the base, slightly tinged with rufous; thorax as wide at base as apex, 

 the hind angles very obtuse and rounded ; elytra about one-half wider 

 than the thorax ; legs pale. Length .09 inch . -bradycelliaus n.sp. 



27. T. niordav Lee. — Form elongate, depressed. Color pale testaceous, 

 shining. Head large, as wide as the thorax at apex; frontal grooves distinct, 

 extending posteriorly behind the middle of the eye; eyes moderate, somewhat
