on the Genus Myllo^na. 43 



Differs from JA r/racilis in its smaller size, narrow elongate 

 form, short eljtra, longer and more slender antenna^, and fuscons 

 colour. 



This and the preceding are very often mistaken for ^f. mlmita, 

 Init maybe distinguished from that species hy their much shorter 

 thorax and elytra ; this difference although very conspicuous, is 

 difficult to determine without actual comparison, not always 

 easily attainable, as the true M . minuta is somewhat rare.

L c. l^-lf lin. = 2-r)0-P>-50 mm. liufo-testaceous, clothed 

 with llavescent pubescence, very convex and rather shining, 

 finely and closely ttiberculate or alutaceous ; head large; thorax 

 rath.er long, widest at the l)ase ; elytra short, much shorter but 

 not broader than the thorax, very obliqtiely truncate towards the 

 suture ; abdomen rather obtusely attenuated, longer than the 

 anterior parts of the body combined, sometimes rather duskv 

 with the apical half of each segment rufous ; legs and antenna* 

 yellow, the latter short and much incrassated. 



Dift'ers from all except M. gnrca in the rufo-testaceous coloiu' 

 of the whole body, and from ^f. qra'ca in its much lai'ger thoi-ax, 

 broad and olituse form, and very robust yellow antenna?. 



M . I)recicornif: is universally distributed, and appears to l)e of 

 a moi'e wandering dis]>ositiou than any of its congeners ; it is 

 the only species of Myllajna which I have ol tained by sweeping 

 herbage, and is sometimes found in wooded and not marshv 

 localities. 



Besides the two novelties described in this Essay, the British 

 List now comprises all the Etn-opean species of IVIyllajna ; since 

 I have been informed by M. A. Fauvel, that the insect intro- 

 duced into this genus in the Catalogue of H. IT. Stein and Weise 

 under the name of }f. paradoxa is not a Af//lla'na, but belongs 

 to Hoincrusa. It is therefore evident that this coiuitry is 

 peculiarly suited to the habits of the genus, and I have no doubt 

 but that fresh species remain to be discovered, if proper attention 

 be given to their pursuit. It may assist in accomplishing this 

 object, if I mention my own long experience in collecting these 

 insects. The localities which tliey frequent have been already 

 nieutioned, but as their proper preservation is on account of their
