Hald. is probably only G. avratus or C. atomus ; the type is not 

 now extant. C. jJumilus, Hald. is closely allied to C. nanus. 



Griburius, Hald. (Scolochrus, Suff.) 



A. Legs yellow. 



B. Ahove black, clj-tra \^itli orange spots. scufellariK. 



Bh. Above yellow, with black spots. larcatus. 



Ah. Legs black and white, elytra with the suture white. Montezximm. 



Ac. Legs entirely black, elytra with two red spots. Lecontii. 



G. speciosus, Lee. appears to me to agree with the description 

 of Scolochrus Montezumee.^ Suffr. G. larvatus may be a pale 

 form of G. scutellaris, but the thorax is less punctate. 



G. Lecontii, sp- n. 



Black, clothed beneath with a gray pubescence; head with the 

 clj'peus and a large triangular frontal mark whitish-yellow; tho- 

 rax shining, with scattered deep punctures and a few minute ones 

 intermixed; base deeply impressed ; scutellura punctate; elytra 

 with the basal half and sometimes an apical spot dull red, deeply 

 punctate striate, the stria? near the suture confused, interstices 

 rujrulose. L. .16. Texas. 



o 



Pachybrachys, Chevr. 



This genus is extremel}^ rich in species and ver3' variable ; 

 Suffrian has described many entirely unknown to me, some of 

 wiiich I cannot think will stand. One species from Lower Cali- 

 fornia appears to me entirely new. 



P. Xanti, ."p. n. 



Ochreous, cylindrical, ver}'^ slightly covered with short erect 

 hairs; head with a brown frontal dash, eyes not closel}' approxi- 

 mate in the J* ; thorax very long, nearly quadrate, witli a smooth 

 discoidal line and no basal impression, ochreous, irrorated with 

 brown, thick!}' covered with deep elongate punctures, interstices 

 faintly punctulate ; scutollum small ; elytra opaque, ochreous, the 

 punctures brown, serially disposed at the sides, irregulail}' towards 

 the suture ; beneath pul)escent, metasternum nearly black. L. .10 

 -.12. Lower California (Leconte).
