176 ENTOMOLOGICAL NEWS. [May, '07 



Described from a single collected by Mr. Spalding and 

 sent me by Mr. Knaus. Most nearly related to gracilis, but 

 differing in the less elongate form, the erect pubescence of the 

 upper surface, less approximate eyes and some other details. 



Substituting macttentus Csy. for nitidipennis Fall, and in- 

 cluding the present species, the table given by the writer in 

 The Canadian Entomologist, XXXVII, p. 276, becomes as 

 follows : 



Table of ALAEPHUS. 



Eyes small, very slightly more prominent than the sides of the front, sep- 

 arated beneath by a distance which is about three times the 

 length of the second antennal joint ; fourth joint of antennas 



barely twice as long as wide pallidus. 



Eyes larger, much more prominent than the sides of the front ; fourth 



joint of antennje from nearly three to four times as long as wide. 



Body subglabrous, the pubescence recumbent and very sparse, fine and 



inconspicuous. 



Eyes separated beneath by a distance which is nearly twice the 

 length of the second antennal joint ; tenth joint of antennae ob- 

 conical, eleventh not shorter ; elytra not much wider at base 



than the prothorax, strongly shining niacilenhis. 



Eyes separated beneath by a distance which is scarcely as great as 

 the length of the second antennal joint ; tenth joint parallel, 

 eleventh shorter than the tenth ; elytra much wider than the 



prothorax at base, moderately shining gracilis. 



Body sparsely but quite conspicuously clothed with short erect hairs. 

 Eyes separated beneath by a distance which is about one-third greater 

 than the length of the second antennal joint, tenth joint paral- 

 lel, eleventh shorter; elytra much wider than the prothorax. 



puberulus. 



In addition to the above synonymy, the following may be 

 announced at this time: 



Microiveisia (Smilia) rcversa Fall = atronitens Csy. 



Scymnus dcntipcs Fall : - the $ of haemorrhous Lee. 



LeptogeniUs virginicus Fall = brcvipennis Csy. 



Corymbites tigrinus is probably only a slight variety of 

 triundulatus Rand. 



Acmaeodera versuta Horn : - the $ of guttifera Lee. 



Agrilus illcctns Fall : : jacobinus Horn. 



Jacobinus is out of place in Horn's table and in the following 

 text, it being assigned to the section having the antcnnre ser-
