ON A NEW SPECIES OF HETMRIUS FEOM TANGIER. 

 BY GEOEGE LEWIS, F.L.S. 



Mr. J. J. Walker cajitured, on the 14th March last, in the nest 

 of a " bright red ant " at Tangier, a new species o£ Hetcerhis which 

 is remarkable in having the hind angles of the thorax acntely produced, 

 and it is the only Ilisterid in the Family in which this character is so 

 conspicuous. 



HeT^ERIUS ACUTANGXTLtrS, tl. sp. 



Breviter ovatus, hrunneo-ferrugineus, sat nitidvs ; thorace dense ocellafo-i 

 punctata, angidis posticis transversim p)roductis ; tibiis antici.'s aspere ocellato 

 punctatis. Long. 2'8 mm. 



Head and thorax densely punctate, punctures ocellated, especially behind the 

 neck. Forehead with two lateral stria;, which are feebly biangulate, and do not 

 meet in front, but continue down part of the clypeus parallel to each other. The 

 thorax is punctate throughout its entire surface, which gives an appearance of 

 opacity, the anterior angles are obtusely produced and slightly reflexed, the sides are 

 narrowly marginate and somewhat parallel for about three-fourtlis of the length, 

 with the posterior angles produced and acuminate. There is a small rather trans 

 verse fovea at the base of the angle, and the scutellum is smooth and triangular 

 The elytra have three striae, 1st complete, 2nd evanescent posteriorly, 3rd basal and 

 short, the dorsal surface is punctulate throughout, with apices of the elytra clothed 

 with erect hairs. Prosternum is broadly canaliculate, the canaliculation being 

 shining, with a few irregular punctures, deep and somewliat narrowed in front, 

 shallow and broad behind, and a little sinuate before the coxae ; the base is broadly 

 emarginate, with the angles on either side produced somewhat acutely behind the 

 coxse. The sides of the thorax beneath are densely and ocellately punctured. The 

 metasternum is finely and feebly punctulate and wholly depressed, the depression 

 anteriorly being so deep that the mesosternum is inclined to be vertical. Propygidium 

 and pygidium feebly and sparsely punctate, the first having erect hairs. The forelegs 

 are opaque, roughly and densely punctate and ocellated, the second and third pairs 

 are smoother on the inner surface, with the tibiae very broad and nearly triangular. 



This species resembles H. Bedeli, Lewis (Ent. Mo. Mag., vol. xxi, 

 1884, p. 83) in the dilatation of the tibiae, but there the similitude
