60 COLEOPTERA. 



36. HoMALOTA voLANS, ScHba, Stett. Ent. Zeit, 1859, 

 413; D. Sharp, 1. c. 122. 



Extremely variable, and extremely close to M. elongatulay 

 than which it appears to be more common here. 



Compared with that species, it has a little sliorter and 

 more slender antennae, wheieof the 2nd joint is rather longer 

 in proportion to the third, and each joint is generally rather 

 more narrowed towards the base ; it is generally smaller, 

 and, if of equal size, proportionately broader; its thorax is 

 shorter; and, in the male, the ventral portion of the 7th 

 segment is broader, shorter, more evenly rounded, and pro- 

 jecting but little beyond the upper plate ; instead of, as in 

 e/ongatula, being nairow and produced considerably beyond 

 the upper plate. In the female of M. volansj also, the out- 

 line of the hind margin of the same segment is not inter- 

 rupted, instead of being a little emarginate. Finally, the 

 setae at the apex of the abdomen are more numerous in both 

 sexes of £[. volans than in elongatula. 



37. HoMALOTA CLAViPES, Sharp, 1. c, 124 (described). 



Dr. Sharp states that this insect can only be confounded 

 with H. elongatula^ from which it may be known by being 

 a little larger, darker, and more shining, with shorter elytra 

 and the punctuation of the abdomen throughout denser and 

 more even. It is, however, certainly capable of confusion 

 with H. eremita. 



Found hitherto only on the higher mountains of Scotland, 

 Ben Lomond, Mamsoul, &c. ; and apparently not occurring 

 in Sweden, in which neither of our two hill species, tibialis 

 or eremitay have been recorded.
