It may be, however, very convenient to use the characters of 

 the under part of the head and of the posterior part of the 

 mesosternum to divide the genus Eupines into different groups. 



The species which are known to me and described or mentioned 

 further on may be distributed as follows : — 



Head with three carina?; mesosternum broad and Hat. 



E. picta,fuscicornis, aurora, polita, tuherosa, bicolor, nodicomis, transversa, 

 pallipes. 



Head with three carina?; mesosternum narrow and Hat. 



K. biclavata. 



Head with three carina?; mesosternum carinate. 



E. nigriceps. 



Head with one carina; mesosternum broad and flat. 



E. melanocephala, soror, nigricollis. 



Head with one carina; mesosternum narrow and flat. 



E. megacephala, longicornis, capitata, diversicolor. 



Head with one carina; mesosternum cariuate. 



E. pumilio, spreta, dubia, pectoralis, liliputana, <-<incol(>r, triangulata, 

 nodosa, sternalis, compressinoda, Imvifrons, Elizabethec, globulifer. 



Eupines picta, Schaufuss.

 var. verticalis, Schfs., I.e., p. 498; var. ebenifer, .Schfs., I.e., p. 498; 

 var. JEthiops, Schfs., I.e., p. 498; heviceps, Schfs., I.e., p. 503. 



This species is rather elongate, generally unicolorous, but some- 

 times the head or the last joints of the antennae are darker. On the 

 head are four fovea? exceedingly variable, two very small ones on 

 the anterior part, on each side of the forehead, and two larger 

 ones between the eyes. They are mere varieties to which Dr 

 Schaufuss thought fit to give names, but which have no specific 

 value. 



The antennae are the same in both sexes, rather stout with the 

 intermediate joints moniliform, 9 a little stronger, 10 large,
