I have specimens of true arcuntns from many Continental localities, 

 and it seems to be as common in most parts of Europe as with us. Of 

 perkinsi, however, I have only found one foreign specimen in my collec- 

 tion, namely, a 5 from " Auvergne " (at least it is so ticketed!), not 

 taken by myself, but perhaps by the late Eev. T. A. Marshall, several of 

 whose captui'es were given to me by Mr. Edward Saunders some years 

 ago. The " saws " of this, as well as its other characters, agree with 

 those of British specimens. A. nitidior Knw. and hrevicornis Knw. 

 somewhat resemble pe)^Jcmsi in general appearance, but the saws of both 

 are as in arcuatus, of which Enslin considers both to be varieties. Also 

 in nitidior the head is expressly said to be shining and very sparsely 

 punctured, and in hrevicornis the tegulae are black. 



The following may serve as a brief diagnosis of the new species : — 



Allantus perJcinsi, n. sp. 



Allantiis A. arcvato simillimus. Differt scutello fere semper immaculato 

 nigro: margine propodei apical! (ut videtur) semper toto flavo : praecipue vero

terebrae $ armatura ut in fig. 2, longe alia aique in arcuato fig. 1, Capitis 

 (desuper visi) latera (inter oculos et verticem) subopaca, confertim rugulose 

 punctata, punctis mag^itudine variantibus, nounusquam confluentibus. Cetera 

 ut in arcuato, sed thorace minus nitido, et flavedine abdominis saepius aliquanto 

 magis extensa.
