less approximate at base; anterior tarsi broadly to moderately dilated, 

 more strongly in the male. Palaearctic and Nearctic regions. 



Baptolinvs 



The foreign genera described in the table may be briefly 

 discussed as follows : — 



Othius Steph. — The assumed type of this genus is re- 

 corded under the name y«?W^emi»s Fab., in the European lists 

 and grandis Hochh., and par all eliceps Qued., can also be in- 

 cluded in all probability. Its species are among the larger 

 and more conspicuous components of the tribe and do not 

 occur outside of the palaearctic provinces as far as known. 

 The shorter and more arcuate mandibles seem to be correlated 

 with the relatively more elongate third joint of the antennae 

 and more abbreviated fourth palpal joint, constituting of 

 Othius and Othiellus a group not very closely related to 

 Baptolimis and Parothius. The peculiar ground sculpture of 

 the elytra, consisting of extremely minute, close-set punctules, 

 only visible under rather high power, constitute a really im- 

 portant character in distinguishing Othius from Othiellus. 



Othiellus n. gen. — This name is proposed for certain 

 very small species, hitherto forming part of the genus Othius 

 but differing in numerous more or less important structural 

 features, as may be inferred from the table above. A notable 

 point of resemblance between the two genera is the sculpture 

 of the pronotum, which in both consists of three setigerous 

 punctures at each side disposed in perfectly similar manner, 

 as mentioned above, but, as a rather radical divergence, 

 attention may be called to the distinct frontal grooves of the 

 present genus, which become obsolete and replaced by a trans- 

 verse post-apical impression in Othius; the tarsi also, are 

 relatively more elongate in Othiellus. The genus ia 

 founded upon such species as laeviusculus Steph., and 

 melanocephalus Grav. 



Parotbius n. gen. 



This genus is rather closely allied to Baptolinus but differs 

 in the important character relating to the number and dispo- 

 sition of the setigerous punctures of the pronotum, stated
