396 SEKKICOENIA. 



flavo-testaceous, with the sides of the metasternum broadly, a broad submarginal band extending down 

 the first three ventral segments, and the fifth segment almost entirely, black, the propleurae with a rufous 

 patch; the antennae and legs black, the base and apex of the femora, the base of the tibiae, and the 

 apical joint of the tarsi, testaceous ; above and beneath thickly pubescent, the pubescence in great part 

 yellowish- or fulvo-cinereous, sometimes obscure fuscous on the dark portions of the elytra. Head 

 thickly, finely punctate, convex, declivous in front; the front a little raised above the anterior margin, 

 the carina obsolete in the centre ; antennae reaching to a little beyond the hind angles of the prothorax, 

 slightly shorter in the female, the joints from the third rather broadly dilated and serrate, 3 and 4 equal 

 in length. Prothorax rather broader than long, convex, gradually and arcuately narrowing forwards, 

 parallel at the base ; the hind angles strongly produced behind, obsoletely and obliquely unicarinate ; 

 the surface closely, finely punctate, canaliculate behind. Elytra moderately long, narrowing from a little 

 below the base, separately rounded at the apex ; shallowly and rather finely punctate-striate, the 

 punctures of each stria distinct, the interstices flat, closely, very finely punctate. Beneath closely, the 

 prosternum and propleurae sparsely, punctured ; prosternal sutures not channelled in front. 

 Length 9-10|, breadth 2^-3 millim. (6 2-)

Five specimens. This peculiar species is allied to A. maculicollis, A. seminiger, 

 A. candezei, &c. The rosy-red lateral marks on the upper and under surfaces of the 

 thorax are only visible in fresh specimens ; the black discoidal patch is shaped somewhat 

 as in A. maculicollis, except that it is divided down the middle in front and is curved 

 downwards at the sides. The head is coloured as in many species of Physorhinus. The 

 oblique thoracic carina is almost obsolete. From A. maculicollis, apart from colour, it 

 differs in the less parallel and more shallowly striate elytra, the punctures of the stria? 

 less closely placed and the interstices flatter, and also in the less transverse thorax. 



11. Anchastus flavovittatlis. (Tab. XVII. flgg. 24, ? ; 25, <s , var. a ; 26, $ , 

 var. /3.) 



Elongate-oval, moderately convex, shining ; the head and antennse black ; the prothorax flavous, with a large 

 transversely cordate patch in front, a rather broad marginal stripe extending from the base to the middle, 

 which extends inwards anteriorly, and the base in the centre, black, the disc between these marks rufous ; 

 the scutellum and elytra black, the latter with a broad submarginal flavous stripe extending from the base 

 to near the apex ; the under surface, the propleurae excepted, and legs black, the base of the femora 

 sometimes paler; above and beneath thickly pubescent, the pubescence variable in colour— in some 

 specimens blackish-brown on the dark portions of the prothorax and elytra, and in others yellowish- 

 cinereous,— that on the under surface yellowish-cinereous, sometimes blackish-brown at the sides and apex 

 of the abdomen. Head closely, finely punctate, the front sharply margined ; antennae reaching consider- 

 ably beyond the hind angles of the prothorax in the male, shorter in the female, moderately stout, joint 3 

 a little shorter and narrower than 4, twice as long as 2. Prothorax convex, about as* long as broad, 

 parallel behind, narrowing from the basal third in the male, more rounded at the sides in the female ; the 

 hind angles strongly produced, acute, obliquely unicarinate ; the surface thickly, finely punctate, deeply 

 canaliculate behind. Elytra gradually narrowing from about the basal third, separately rounded at the 

 apex ; punctate-striate, the interstices feebly convex and thickly punctured. Beneath thickly punctured ; 

 prosternal sutures channelled in front. 



Var. a. The prothorax rufo-testaceous, with the black marginal mark obliquely narrowing forwards, and not 

 extending inwards anteriorly, the anterior black patch more extended laterally. (Pig. 25.) 



Var. 0. The prothorax rufous, with the tips of the hind angles and the basal margin In the centre black 

 (Fig. 26.)
