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 macilentus 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 ALAEPHDS. 

 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 antennae 



barely twice as long as wide pallidus. 



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

 joint of antennae 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 macilentus. 



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 tban the prothorax. 



puberulus. 



In addition to the above synonymy, the following may be 

 announced at this time: 



Microweisia (Smilia) reversa Fall = atronitens Csy. 



Scymnus dentipes Fall = the $ of haemorrhons Lee. 



Leptogenius virginicus Fall = brevipennis Csy. 



Corymbites tigrinus is probably only a slight variety of 

 triundidatus Rand. 



Acmaeodera versuta Horn == the $ of guttifera Lee. 



Agrilus illectus 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 antenna? ser-
