Anaspis.] HETEROMERA. 75 



1. Elytra variable In colour, blackish or brownish, 



but without spots A. rr.AVA, L. 



(y. thoracica, L.) 



2. Elytra very light testaceous v.-ith obscure dark 



spots A. MACtTLATA, FourC. 



A. frontalis, L. (asshnilis, SnelL). Elongate, subfusiform, black, 

 clothed with very fine fuscous-grey silky pubescence, with the base of 

 the antennae, front of head, and the anterior legs, except more or less of 

 upper margin, yellow or reddish-yellow; the whole of the coxae are often 

 more or less ferruginous ; head very finely punctured, antennae rather 

 long, with joints 6-10 gradually increasing in length and not monilitorm; 

 thorax not much broader than long, narrowed in front, with the pos- 

 terior angles almost right angles, sculpture very fine; elytra transversely 

 strigose, the sculpture being distinct, but finer than in the allied species 

 and much stronger than that of thorax ; tibial spurs testaceous. L. 

 2f-4 mm. 



Male with the antennae longer than in female, the anterior tarsi with 

 the first joint transverse, slightly dilated, and the second and third 

 joints oblong, strongly dilated ; the third ventral segment of the abdo- 

 men is narrowly emarginate in the middle, and is furnished with two 

 narrow laciniae or appendages which are approximate at base, and gradu- 

 ally diverge and curve inwards towards each other at apex ; these 

 appendages almost reach the apex of the abdomen. 



Female with the antenna? slightly thickened towards apex, abdomen 

 simple. 



On flowers of white-thorn, by sweeping among grass, &c. ; common and generally 

 distributed throughout the kingdom. 



The yellow colour of the front of the head is variable, extending some- 

 times over a greater and sometimes a lesser extent of surface; a 

 variety occurs on the Continent (A. lateralis, F., nee Thorns.), in which 

 the yellow colour extends to the front and sides of thorax ; I have not, 

 however, seen any British examples. 



A. G-arneysi, Folder. In size, shape, and general appearance closely 

 resembling A. frontalis, from which it may be known by the somewhat 

 longer and more slender antennae and more evident sculpture, wlr'ch is 

 intermediate between that of A.frOBtaKssoHA. iitnlabris ; the legs also 

 are differently coloured, the anterior pair being clear yellow, with the 

 exception of the apex of the femora which is dusky above; the inter- 

 mediate and posterior femora are also entirely, or almost entirely, yellow, 

 the tibue being more or less variegated ; the tarsi are fuscous ; the 

 antennae are long and slender with the joints much longer than broad; 

 the thorax is scarcely broader at base than its length from base to 

 apex ; the chief difference, however, lies in the male characters ; in this 

 sex the third segment is much elongated, and is furnished with two rather 

 stout and' widely separated appendages, which are strongly curved
