sembles, by the form of the penultimate joints of the anterior 

 legs, which are not bilobed, by its distinct scutellum and acu- 

 minated abdomen. They inhabit flowers, especially theUmbel- 

 latae, fly as well as run with celerity, and when alarmed draw 

 their head close under the thorax, so that the mouth is con- 

 cealed between the anterior coxa?. 



The following are British species : 



1. M. abdominalis Fab.— Curt. Brit. Ent. pi. 483. — Oliv. 3. 



No. 64>,pl. l.f. 5. 

 May, White-thorns and umbellate plants, the beginning 

 and middle of June in the New Forest, but rare; near Swansea 

 not uncommon, L. W. Dillwyn, Esq. 



2. M. pumila Gi/l. 2. 605. 2. 



Middle of July, Bungay, Suffolk ; and near Swansea on 

 umbellate flowers. 



3. M. aculeata Liim. — OL pi. l.f. 1. 



May and June, blossoms of Crab-tree and White-thorn, 

 Mr. Samouelle, and near Swansea. 



4. M. ventralis Fab., Gijl. — nigra Mars. 



10th of June, Blackwell Sands, Devon, Mr. Chant and 

 Mr. Bentley, in company with the last, also in Kent. 



5. M. humeralis Linn. — Mars. — Panz. 62. 3. 

 July, Coomb-wood, Surrey. 



5^ M. axillaris ? Gyl. 2. 61 1. 8. 



6. M. variegata Fab., Gyl. — lateralis Oliv. 'pl. 1. f. 8.— 



bicolor Mars. — dorsalis Panz. 13. 15. 

 May and June, White-thorns Norfolk, but rare ; also at 

 Darent, Kent. 



7. M. brunnea jPaZ>. ? — Panz. 36. 8. I gave this and the 



next as synonymous, on the authority of Schoenherr, 

 but whether they be distinct or varieties only, I am 

 unable to determine for want of specimens. 



7*. M. flavescens Mars. 490. 7. — ferruginea Mars. 490. 6. 

 May and June, White-thorns, Swansea. 



8. M. fasciata Fab.— Oliv. pl. l.f. 2.—Sam.pl. 4./ 8. 

 Plentiful in the New Forest in June, where I found them 



on fine days flying round and running up dead decaying trees, 

 that were standing, deprived of their bark. Mr. Dale has 

 found them on the Teasel, and Mr. Bydder observed them 

 flying about Oak-trees. 



The Plant is Viburnum Opidus (Guelder Rose), to the flowers 

 of which the Mordellidae are much attached.
