364 Goleopterological Notices, VII. 



The subgenera of Euconnus within our faunal limits may thus 

 be defined : — 



Antennal club 4-joiiited, very variable in development and in abruptness of 

 formation. 



Elytra with long, erect and very sparse hairs ; head sparsely pubescent ; 

 clypeus separated from the front by a fine transverse canal Joiniug the 

 antennal cavities ; antennae generally long ; eyes not prominent ; poste- 

 rior coxae rather widely separated ; male with well marked secondary 

 sexual characters on the surface of the abdomen I 



Elytra abundantly pubescent, the dense and stiff pubescence of the head 

 directed backward as in Connophron ; clypeus not separated by a trans- 

 verse sulcus ; antennae generally shorter, with a more abrupt club ; eyes 

 more prominent ; hind coxae very narrowly separated ; secondary sexual 



characters of the male not apparent II 



Antennal club 3-jointed. 



Clypeus not porrect, its surface almost evenly continuous with the wide 

 convex front between the antennal cavities ; pronotum, in addition to the 

 usual median foveae, with a lateral subbasal fovea and a minute and 

 rudimentary cariniform elevation at the basal margin only ; hind coxae 

 quite widely separated ; head and elytra glabrous Ill 



Clypeus slightly porrect, the surface between the antennal cavities tumid ; 

 pronotum with a fine but long and well defined longitudinal carina at 

 each side, extending obliquely to the base ; hind coxae but slightly less 

 widely separated ; head and elytra distinctly though rather sparsely pub- 

 escent, the hairs of the former not directed backward ; species minute IV 



The species assigned below to Euconnus proper, agree satisfac- 

 torily with European species of the hirticoUis type, except that 

 the hind coxse are more widely separated and the sublateral 

 carinse of the pronotum much less developed, in fact in some 

 forms, such as ventralis, becoming completely obsolete; but this 

 is a very variable character also in the European species. Those 

 known to me may be recognized as follows: — 



Subgenus I. 

 Euconnus Thoms. 

 Secondary sexual characters of the male confined to the third and fourth ven- 

 tral segments; head always much narrower than the prothorax. 

 Large, stouter, the antennae very slender, with all the joints distinctly 



elongate 1 ventralis 



Smaller and more slender, the antennae less elongate, the penultimate joint, 

 at least, not distinctly longer than wide. 

 Lateral carina of the pronotum extremely rudimentary and only visible 

 at base; secondary male sexual characters large and conspicuous.
