sinuate at the base. In A. brouni the basal margins of the thorax 

 and elytra are about equally well developed; in this species the 

 elytral margin only is distinct. The elytra are not so closely 

 punctured, and there is an indistinct longitudinal line along the 

 middle of each. 



Fern. Eyes less convex, thorax larger than in A. brouni, scutellum 

 also larger and more polished. 



$ . Length, If lines ; breadth, f line. 



Boatman's. Cavell ; one male and a mutilated female. 



Group GALERUCID^E. 



Phyllotreta (Gen., p. 635). 



2427. P. graminicola, n.s. Convex, oval, glabrous above, 

 glossy, cupreo-niger ; femora rufo-piceous, the tibiae, tarsi, and four 

 or five basal joints of the antennae pale-chestnut, remaining joints 

 of antennae pitchy-brown. 



Head nearly smooth, with some grey hairs in front. Thorax 

 rather broader than it is long, its sides finely marginated and a 

 little rounded ; it has a few indistinct, fine, shallow punctures, the 

 base has no well-marked transverse sulcus. Scutellum broadly trian- 

 gular. Elytra obovate, widest before the middle, much narrowed 

 posteriorly ; estriate, their punctuation rather distant, shallow, and, 

 on some parts, nearly serial ; the base, on each side of the scutellum, 

 is a little raised and smooth, and just behind this there are several 

 rather conspicuous punctures which almost form a transverse row. 



The antennas are long but not slender, they are inserted near 

 the front and inner margin of the eyes, but there is a smooth space 

 between the point of insertion and the eye ; the basal joint is larger 

 than the second, the fifth is rather longer than the contiguous ones, 

 all the joints are longer than broad. Legs stout ; posterior femora 

 very broad, the tibia notched or broadly sulcate near the extremity, 

 appearing somewhat angulate near the middle, the external or 

 lower edge of the groove is densely fringed with outstanding grey 

 hairs, and the upper or inner face is pilose ; the terminal mucro is 

 small and extends in the outward direction ; intermediate shorter, 

 of similar form ; posterior tarsi with the basal joint quite one-third 

 of the length of the tibia. 



This and the two following species are at present represented 

 by single specimens only, their generic characters cannot therefore 

 be properly studied. They are referred to Phyllotreta until more 

 material can be obtained.

2428. P. littoralis, n.s. Shining, black, elytra viridescent, 

 femora rufo-piceous, tibiae castaneous, five basal joints of antennae 

 pale-chestnut, remaining joints piceous.
