POLYCYKTUS. 241 



28. Polycyrtus erythrosternus. (Tab. IX. fig. 20.) 



Rufus, nitidus ; eapite, pronoto, mesonoto antennisque, riigris ; annulo antennarum, orbitis, linea pronoti^ 

 tegulis, lineis 2 mesonoti, scutelli apiceque, flavis ; abdominis dorso fusco variegato ; alis hyalinis, stigmate 

 testaceo. 



Long. 14 minim. 



Hab. Panama, Bugaba (Champion). 



Antennae longer than the body, a little thickened and compressed towards the apex \ 

 the annulus broad. Front projecting, the projecting part narrowed towards the apex 

 and depressed below the antennae ; the spine conical, semi-obtuse at the apex ; a 

 tubercle at its base. Orbits from the middle to the back broadly white ; a whitish 

 mark in the centre of the clypeus at the apex ; sides of the mandibles yellowish ; palpi 

 reddish yellow. The mesosternum is reddish yellow, black in front ; the yellow line 

 on the edge of the pronotum is broad ; the carinse in front of the scutellum yellow. 

 Scutellum black on the top, reddish at the sides, and yellow at the apex. Transverse 

 keel on the metathorax acute, a little curved upwards in the middle ; the base of the 

 metanotum somewhat depressed in the centre. Tubercles large, curved, semi- acute at 

 the apex. Metapleurse with scattered punctures. The ground-colour of the abdomen 

 is obscure red ; the sides incline to yellow, and the back, from the second segment, is 

 fuscous, the apices of the segments being much lighter, almost reddish, in tint. The 

 scutellum and metathorax are sparsely covered with long pallid red hair ; the apex 

 more densely with fuscous hair. Sheath of the ovipositor black, microscopically pilose. 

 The hind tarsi are yellow, black at the apex ; the four anterior ones black, except the 

 basal joint, which is reddish. 



Allied to P. rujlventris, Brulle, from Brazil; but may be known from it by the 

 fuscous colour of the abdomen, the absence of white marks on the mesothorax (except 

 the scutellar keels), and the reddish post-scutellum, while the metathorax is differently 

 formed. 



29. Polycyrtus atriceps.

 Hab. Mexico, Orizaba 1 (Sumichrast). 



30. Polycyrtus tinctipennis. (Tab. IX. fig. 19.) 



Bufus ; capite (ore excepto) antennisque nigris, flagello antennarum annulo albo ; tarsis posticis pallide flavis ; 



alis flavo-nyalinis, stigmate rufo-testaceo. $ et <$ . 

 Long. 13-14 millim. ; terebra 4| millim. 



Bab. Panama, Volcan de Chiriqui, 2000 to 6000 feet (Champion). 



Smooth, shining, impunctate ; thorace sparsely covered with long reddish hairs ; apex 

 of the abdomen densely covered with longer hairs, also red. Antennae a little longer 

 than the body, thickened and compressed towards the apex, covered with a microscopic
