92 COLEOPTERA. 



49. Malthodes atomus, Thorns. Skand. Coll. vi. 202, 6; 



hremcollis, Kies. ; Wat. Cat. {nee Payk.) 

 Mr. Crotch (Joe. cit.) points out the above change in 

 nomenclature. 



50. Malthodes fibulatus, Kies., Linn. Ent. ; id. Ins. 



Deutschl. iv. 552, 17 ; Thorns. Skand. Col. vi. 204, 8. 



Mr. Crotch (loc. cif.) states that there are several ex- 

 amples of this species in Mr. Wollaston's Collection, 

 apparently from Cambridge, and that he has seen a spe- 

 cimen in that of Dr. Power. 



It appears to be unicolorous, differing from 31. mysticus 

 by its antennae being pale at the base ; and is in Thomson's 

 section wherein the thorax has the sides not margined, and 

 the anterior angles elevated. 



51. Malthodes pellucidus, Kies., Linn. Ent.; id. Ins. 



Deutschl. iv. 537, 4; Thorns. Skand. Col. vi. 206, 



10. 

 Mr. Crotch {he. c'lt.) has two or three females probably 

 referable to this species, and has recently seen a male from 

 Dr. Power which he thinks belongs to it. It is stated to be 

 not unlike 31. marginatus, but smaller, the antennae with the 

 base dark, and anterior tibiae pale. 



52. Malachius ruficollis, Olivier, Ent. ii. 27, 9, 10, 



T. 2, F. 9 (1790) ; Kiesenw. in Er. Ins. Deutschl. iv. 



594, 3; G. R. Crotch, "The Entomologist," vol. i. 



pp. 209, 214. 



Mr. Crotch (following Kiesenwetter, loc. cit.) remarks 



that J/, ruhricollis, Marsham, is identical with this species; 



Olivier's name being the oldest, and therefore entitled to 



priority : also, that the smaller species of 31alachius have
