Tins is a very common insect throughout the country, from July 

 until late in October. It varies considerably both in colour and size : 

 I have a dwarfish specimen no larger than the following species. 



ft Vertex pronoto longior, carinulis 3 longitudinalibus. 

 2. — 'Acoceplialus bifasciatus, Lin. 



Vertex dimidia sua inter oculos latitudine longior, medio indistincte 

 tricarinatus. Antennae fronte briviores. Supra subtilissirae punctulatus. 

 Alae rarissime completae. ,^ $ . 



^ . Niger vel nigro-brunneus, sub-nitidus. Pronotum basi, heme- 

 lytra medio et versus apicem albo-fasciata. Frons, pectus, pedes, 

 albida ; femora apice, tibiae auticjc et postica? fere totse, nigra. 



$ . Color variat ; flavo-brunneus vel griseus, hand nitidus. Supra 

 plus minus atomis nigris vel fuscis irroratus. Hemelytrorum ncrvi 

 pallidi atomis nigris interspersis. Pedes pallidi ; coxse, femora basi et 

 medio, alba. Long. l|-2 ^ ; 2i-2| lin. ? .

This handsome and well-marked species seems to be not very 



common with us, but is widely distributed. Single specimens of the 



black and white ^ are in several collections, but the $ was unnoticed 



in England until last July, when I succeeded in obtaining it, with the 



other sex, from a meadow near Leicester. Mr. T. J. Bold takes the 



^ at Newcastle, and Mr. Curtis mentions Weston-on-the- Green, near 



Oxford, and Whittlesea Mere, as the localities for his tricinctus. The 



$ is intermediate in size between that of A. rusticus and A. albifrons, 



and distinguished from either by the greater length of the vertex, and 



the abbreviated wings.
