NEW SPECIES OF THE FAMILY ELATERID^ 



(COL.). 



By Chas. Schaeffer, 



Brooklyn, N. Y. 

 Alaus zunianus Casey. 



This species is placed as synonym under lusciosiis in our list. 

 However, two specimens from Arizona received from Mr. G. Francl^* 

 and others which I have seen show sufficient differences from lusci- 

 osiis to entitle it to be restored. 



The thorax is more strongly sinuate before the basal angles, the 

 outer antennal joints are slightly more transverse, the underside is 

 covered with black scale-like hairs, with a large patch of white scale- 

 like hairs on each side of prothorax and at sides of each abdominal ' 

 segment a smaller white patch. The legs are covered with black 

 hairs only and the last ventral segment is much more densely punctate 

 with very few small punctures intermixed at middle. 



Aptopus subcarinatus new species. 



Elongate, piceous ; antennae, palpi, mandibles and legs testaceous ; pubes- 

 cence short, greyish. Head moderately closely punctate ; antennae reaching 

 far beyond the hind angles of prothorax, third joint very distinctly shorter 

 than fifth. Prothorax as long as wide at base ; sides without acute margin, 

 slightly arcuate to a little before basal angles; the latter divergent ; surface 

 unequally punctate, a few larger punctures intermixed with the smaller punc- 

 tures ; punctures well separated on the disk, a little more close near apex and 

 sides ; hind angles rather feebly carinate, the carina not acute and almost 

 obliterated. Elytra about two and one half times as long as the prothorax; 

 sides feebly arcuatcly narrowing to apex ; striae feebly impressed and with 

 moderate punctures. Prosternum finely and sparsely punctate ; propleurae 

 densely punctate with small punctures ; metasternum moderately closely punc- 

 tate and with larger punctures intermixed; abdomen finely and rather closely 

 punctate. Length 8 mm. 



Huachuca Mts., Arizona (Schaeffer). 



Some specimens have the punctuation of prothorax a little stronger 

 and closer, in these the dual punctuation is not so pronounced.
