POLYCYETTTS. 235 



Hdb. Guatemala, San Geronimo (Champion). 



Head, pro- and mesothorax coloured as in P. montezuma ; the mandibles only black 

 at the base ; apical half of the scutellum yellow ; frontal spine shortish, conical. Meta- 

 notum with a broad black mark at the base, which is not joined to the black suture of 

 the metapleura ; a broad band runs down the centre from the base, where it is not 

 dilated ; a narrower line runs down from the spiracles ; there is no transverse line, and 

 the transverse keel is 'distinct ; behind it in the middle is an indistinct, somewhat 

 triangular, area ; a suture runs from it down the black central line ; pleurae transversely 

 punctured ; spines broad, longish. First abdominal segment black, except at the apex 

 and along the sides ; second segment with a black line along the base and continued 

 along the sides for about the basal third of the segment ; in front of this is a large black 

 mark, narrow at the base, the apex transverse, the sides not rounded ; basal half of the 

 third segment black ; the other segments narrowly lined with black. There is a black 

 mark on each coxa, and a somewhat obscure black line over the femora and trochanters 

 (this latter interrupted) ; the base of the hind tibiae is black. 



The second abdominal segment is marked very much as in P. montezuma and 

 P. blanditus ; the former, however, has the central black mark longer and slightly 

 indented at the base, the apex being transverse, while in P. canaliculatus the sides are 

 cut off; the latter has the base not rounded as in P. canaliculatus, but sharply truncated, 

 and at the apex the sides project. Neither of the above species has the black line on 

 the metanotum sulcated. 



11. Polycyrtus blanditus. (Tab. IX. fig. 21.) . 



Long. 15 millim. 



Eab. Guatemala, El Eeposo 800 feet (Champion). 



Smooth, shining, impunctate ; the sides of the prothorax longitudinally striated. 

 Antennse longer than the~body, the white ring broad and placed near the apex ; pilose. 

 Ocelli raised ; two carinse run from them to the frontal spine (which is broad and 

 rather obtuse) becoming more distinct as the spine is reached. A large fovea imme- 

 diately below the antennse. Apex of the clypeus and the base of the mandibles black. 

 Sides of the prothorax depressed ; in front is a sharp margin, from which, at the top, 

 an oblique keel runs to a large semilunate depression at the apex. Sutures of the 

 mesonotum deep ; a short keel in the centre of the middle lobe at the base. The pro- 

 thorax is black, except the presternum and a broad mark on the edge above. 

 Mesonotum black ; two short yellow lines in the middle ; the keels in front of the 

 scutellum, and the apical half of the latter, yellow; the pleurae below the wings are 

 black, as well as the sutures ; the sutures between the meso- and metanotum and the 

 postscutellum are yellow. Metathorax yellow, the base broadly black ; a broad black
