testaceous, with tlie tibise, except at tlie base, piceous or fuscous, and the tarsi, except 

 at the base of the first and second joints, infuscate, the hind pair piceous, the 

 exti-erue base of the tibiae excepted ; the tibial spurs testaceous ; the anterior and 

 middle tarsi slender in both sexes. 



$. Anterior tarsi very feebly dilated ; anterior and intermediate tibiae sinuate 

 within, the anterior pair slightly curved inwards towards the apex. Third ventral 

 segment elongated, produced in the middle behind, and furnished at the apex with 

 two long lacinise or appendages, these latter narrowly separated at the base, almost 

 straight, extending to the middle of the fifth segment, and becoming slightly diver- 

 gent posteriorly, the space enclosed by them unimpressed ; fifth ventral segment 

 very deeply and abruptly emarginate at the apex, but not at all depressed in the 



middle in front of tlie emargination. 



Length (with the head extended) 3^ — 31 mm. (<??). 



Two examples of this species were captured by myself at Avie- 

 inore, Inverness-shire, in July, 1876. A. septentrionalis is closely 

 allied to A. frontalis, Linn., but may be easily known from it by the 

 more slender legs and antennae, and by the well-marked male characters. 

 The male of A. frontalis has the fifth ventral segment broadly excavate 

 in the middle from the apex nearly to the base* (this part being quite 

 unimpressed in A. septentrionalis), and the apex much less deeply 

 emarginate ; the lacinise very distinctly curved inwards at the apex ; 

 and the anterior tarsi strongly dilated (very feebly so in A. septen- 

 trionalis). The antennae in the male of A. septentrionalis are very 

 elongate and slender, the insect thus resembling A. Oarneysi, Fowl., 

 but this latter has the lacinije strongly divergent and curved, and 

 enclosing a large broad space ; the anterior tarsi are equally slender 

 in these two species, and only very feebly dilated in the male. In the 

 female of A. septentrionalis the intermediate legs are a little darker 

 than in the male. The different male characters, &c., distinguish it 

 from A.pulicaria, Costa, and A. ni^rip eSjBris., and the non-moniliform 

 antennae from A. ruflabris, Gyll., and A. melanostoma, Costa. 



Mr. Fowler remarks (op. cit., p. 331) that the genus Anaspis may 



be more widely spread than at present known : it is more probable, 



how^ever, that it will prove to be confined to the Palaearctic and 



Nearctic regions, as in North America the genus only just reaches the 



southern boundary of the United States, and is replaced in Mexico 



and southwards by Pentarin and an allied genus ; the single species 



recorded from the Australian region is in all probability not a true 



Atiaspis.
