SYNOPTIC TABLES OF COLEOPTERA. o3. 



By Geo. H. Horn, M. D. 



B LECH R US, Motsch. 



This genus is composed of a small number of black shining species 

 differing from the allied genera either by the slightly lobed base of thorax, 

 the mentum not toothed, or the claws serrate. The ligula proper is small 

 and bi-setose at tip, the paraglossae rather wide, and completly surround- 

 ing the ligula. In examining the illustrations of the mouth parts (Trans. 

 Am. Ent. Soc. IX, pi. VIII, figs. 86, 87, 88, 89 and 90) it will be ob- 

 served that Bfechrus and Axinopalpus have the ligula bi-setose in front. 

 Aprisius and M.iMtius quadri-setose, and Dromius sex-setose. 



The species of Bkchrus are separated by Dr. Horn as follows: 

 Thorax very distinctly wider than long, broadest about one third from apex. 



Elytra faintly sub-striate at middle IligrinUS, Mann. 



Thorax not wider than long, widest immediately behind the apex. 

 Elytra almost smooth. 



Elytra longer than head and thorax, sides nearly parallel luci&US. Lee. 



Elytra not longer, sides distinctly arcuate pusio, Lee.

The species here placed were formally considered to be Philotecnus 

 =Cymindoidea. Chaudoir has corrected this. 



The various forms occurring in our fauna seem to constitute one 

 species with the following varieties. 



var. Pilatei, Chaud. Head, thorax, antennae and legs yellowish red, elytra blue. 

 var. ruficollis, Lee. As in Pilatei with the antennae brownish, legs piceous. 

 var. croceieollis, Men. As in ruficollis, the head darker, becoming piceous. 



var. . As in croceieollis, with the thorax becoming brown. 



var. nigricollis, Lee. Head and thorax piceous.
