fl8 THOS. L. CASEY. 



DENDROPIIAOUS Schon. 

 Meiitmn strongly transverse, sinuate anteriorly. Ligiila corneous, feebly emar- 

 ginate anteriorly. External lobe of maxillae short and broad, ciliated at the tip; 

 internal lobe small, terminated by a corneous hook. Palpi short and robust, the 

 last joint ob-conical. Mandibles short, arcuate, bidentate at the tip, and provided 

 with a ciliated border internally. Labrum transverse, truncate and ciliated ante- 

 riorly. Eyes small, rounded, not prominent. Prothorax elongate, parallel and 

 entire. Legs short, femora enlarged near the middle, and compressed; tibiae 

 straight, terminated by a very short spur. Tarsi pentamerous, slender; first joint 

 very short, second and third longer, sub-equal, fourth short, last very long. Body 

 very depressed. 



We have but one species. 



1. D. glaber Lee. — Form elongate and depressed; sides parallel. Surface 

 deeply and coarsely punctured, punctures closer on prothorax than on head ; 

 elytra striato-punctate; covered v^y sparsely with fine short setae, which are 

 longer and closer on the under side. Color dark brownish black. Head sub- 

 quadrate, with two lateral grooves from the front, which do not extend to the pos- 

 terior margin. Prothorax one-half as long again as the head, as broad as the latter, 

 and not margined; anterior angles rounded, sides parallel and in-curvate before 

 the middle, then converging rapidly behind. Elytra twice as long as the head and 

 ])rothorax together, much broader than the latter, entire and evenly rounded 

 behind; sides parallel and straight. Antennae nearly as long as the elytra, fili- 

 form, first joint as lon^ as head, second very small, third longer, fourth to last 

 sub-equal, last joint narrowly acuminate at tip; all moderately pubescent. The 

 legs and antennae are a little paler in color than the body. Length ^.8 — 7.0 mm. 



Plate VIII, Fig. 2. 



Very widely distributed throughout the Northern regions of the United 

 States and in British America. Resembles the European species, of 

 which it is probably a variety only. 



I have under examination a specimen from the N; W. Territory, which 

 I am forced to refer to this species. It however represents a rather re- 

 markable variety, and is undoubtedly the same as Mannerheim's D. 

 nmericanua. It is a little more than two-thirds the length of the normal 

 form, and of a very light color. The elytra are paler in color at and 

 near the humeri. The prothorax is also relatively a little more coarsely 

 punctured. 



Although this may re})resent a genuine species, I am unwilling to re- 

 gard it in that light without other specimens. 



BRONTEfii Fab. 

 Differs from the preceding in the following characters : 



Ligula corneous, cordate ; last joint of the maxillary palpi ovulate and acumi- 

 nate at the tip, that of the labial cut very obliquely, and prolonged in a long acute 

 process. The genus is cloisely allied to Dendrophagns and differs only in the 

 above characters and those mentioned in the table.
