Somewhat close to H. rustica, but very differently col- 

 oured, with the pronotum very much more finely punctulate, 

 etc. It is unlikely that the male differs much from the fe- 

 male except by the longer laminae of its antennae. As the 

 unique type of this insect has already lost one of its maxillary 

 palpi, I have not been able to risk a satisfactory examination 

 of a palpus ; but I can see (without unsafe manipulation) 

 that, although the second joint is partially concealed, there is 

 at least not much difference from the palpi of //. rustica.

Very close to JI. fraff^rfu/, Blackb.. and differing chieffy 

 by sexual characters. In the male the antennal laminae ai'e 

 scarcely shorter than the clypeus (in fraterna notably short- 

 er). In the female the antennal laminae are very little shorter 

 than in male frdtcrmi, but the basal lamina (i.e.. that of tlie 

 6th antennal joint) equals only about one-seventh of the 2nd 

 lamina in length (in fraterna the longer laminae are not- 

 ably shorter than in electa, but the basal one equals in 

 length nearly half the 2nd). In electa the male j^ronotum 

 is less strongly punctured than the female, but in fraterna 

 the pronotum of both sexes is punctured like that of male 

 electa.
