with the first joint of antennae pale. Prothorax rather coarsely punctate 

 and the elytra with a fascia of white hairs below middle. Length 3.5 mm. 



Aulonothroscus rugosiceps new species : Piceous, moderately shining, sur- 

 face moderately densely pubescent. Head coarsely and densely punctate, 

 more or less distinctly carinate laterally near each eye and also with a 

 short, irregular carina at middle; eyes entire. Prothorax about twice as 

 wide as long; sides arcuately narrowing from base to apex; hind angles 

 with a 'relatively long carina ; surface moderately coarsely but not densely 

 punctate, intervals between the punctures minutely punctulate. Elytra 

 slightly narrowing posteriorly; striae very feebly impressed, almost oblit- 

 erated on the disk; intervals irregularly punctate with very minute punc- 

 tures intermixed. Prosternum very sparsely punctate; lateral striae deep, 

 parallel and entire. Metasternum and abdomen rather coarsely punctate. 

 Length 4 mm. 



Brownsville, Texas (O. Dietz). 



The entire eyes and the long, entire prosternal striae relate this 

 species to A. constrictor, from which it differs in the distinctly 

 carinate hind angles of prothorax, the carinate head and the 

 absence of the basal impression, which is very pronounced in A. 

 constrictor. 



The head is unusually coarsely punctate with the punctures' 

 here and there confluent. 



Throscus carinicollis new species : Brown, feebly shining, surface densely 

 but not coarsely pubescent. Head sparsely punctate in front with a rather 

 distinct carina near each eye; eyes nearly divided. Prothorax wider than 

 long, sides feebly arcuate and rather strongly narrowing from the basal 

 to the anterior angles ; basal angles rather strongly carinate ; disk moder- 

 ately coarsely punctate, on each side of middle near base a more or less 

 distinct impression. Elytra scarcely narrower than the thorax, slightly 

 narrower posteriorly; surface punctate striate; intervals biseriately punc- 

 tate with larger punctures, intermixed with very minute punctures. Pro- 

 sternum sparsely punctate near apex, punctures absent or obliterated in 

 about basal half ; striae deep, entire and nearly parallel. Metasternum and 

 abdomen moderately coarsely punctate. Length 3 mm. 



Elk Co., Pennsylvania. 



This species is very close to chevrolati from which it differs in 

 having a very distinct carina at the hind angles of prothorax, less 

 coarse pubescence and punctuation and a more distinct ante- 

 scutellar impression at base of prothorax. 



I have also specimens from New Jersey.
