marginal nerve testaceous ; posterior margin straight, angles rounded. Legs 

 pale fuscous-testaceous ; tihioR darkest j tarsi testaceous ; apex of tlie third 

 joint and claws brown. 

 Abdomen black, with a narrow yellowish dorsal line ; sides with a yellow spot at the 

 posterior angle of each segment ; genital segment black ; styloid processes 

 somewhat billhook-shaped, the points above turned towards and touching each 

 other. 



Uudeyeloped form, $ . Testaceous. 



Abdomen above testaceous, with a fuscous shade, sides with two longitudinal, pitchy- 

 brown lines interrupted at the anterior margin of each segment. 



Length I5 line. 



On tlie nerves of the elytra of tlie ? I possess, and also on 

 otliers (but not all), in the collection of M. Lethierry, are some 

 minute pitchy-brown or black granules, but these are so irregularly 

 placed, and so different in position on each elytron, that I believe them 

 to be accidental, and not characteristic of the species. 



The only other insect I know referable to this section is our 

 i. mesomela; the white head, pronotum, and elytra of which will at 

 once distinguish it from the species now described.

[Revision of the genus STRONGXLOCEPHALrs, and description of 

 a new species.^ 



In the revision of the genus Acocephahis, Ent. Mo. Mag., vol. ix, 

 p. 264, I refer to Flor's removal of the then only known species from 

 the last named genus, on account of the very perceptible differences in 

 the structure of the head alone, to that of his genus Strongylocephalus. 

 At the time I then "OTote, I had not seen a British exponent of agrestis, 

 Eall., and it is only within the last few days that I have had this 

 pleasure. The number of insects I have examined and supposed to be 

 this species is very great. In each and every instance, they have 

 proved to be the Athysanus ohscurellus, Kirschb., an insect as unlike 

 the true S. agrestis as any two insects could reasonably be. My friend 

 the Rev. T. A. Marshall's description of Acocephahis agrestis, Ent. 

 Mo. Mag., vol. ii, p. 197, will therefore require to be referred to 

 Athysanus ohscurellus, as also the insects representing it in his col- 

 lection, which last he has kindly allowed me to have in my possession 

 for many months. I had begun to think that the genus Strongylo- 

 cephalus had no representative here ; but some few months before the
