98 EKOTYLIDJE. 



black, with the elytra and abdomen dark fulvous-red; the former punctate-striate, 

 but with the first four striae only distinct at the base, and all obliterated before the 

 apex, and those external to the short fifth stria also quite obliterated. The head and 

 thorax are glabrous ; the antenna? entirely black. The prosternum is compressed, but 

 not elevated or pointed, in front. The scutellum is pitchy-red in the San Geronimo 

 specimen ; in two others from Chiacam it is black. B. fulviventris is the only known 

 species of this convex oval form, acuminate before and behind, with the abdomen red, 

 which has the striae obliterated externally. In the San Geronimo specimen the coxse 

 are red also, but it does not appear to be distinct from those from Chiacam. 



15. Brachysphenus scutellaris. 



Oblongus, ferrugineus ; antennis (articulis duobus basi scutelloque rufescentibus), femorum apicibus, tibiis 

 tarsisque nigris; prothoracis lateribus antice angustatis, angiitis anterioribus et posticis acutis, disco 

 opalescente. Long. 10 millim. 



Hab. Guatemala, Cerro Zunil (Champion)', Nicaeagua, Chontales (Belt); Costa 

 Rica ( Van Patten). 



Very nearly allied to B. rubidus, Duponch. ; but differing from it in having the 

 scutellum black and the upper surface of a less sanguineous -red colour, as well as in 

 minor details. 



The antennae are thinner and have all the joints (especially those intermediate 

 between the second and the club) longer. The lobe in the middle of the base of the 

 thorax has its tip black in two examples, viz. in the one from Guatemala, and in 

 another from Costa Eica, and these have also the extreme limb of the lateral margins 

 of the thorax and elytra black. The opalescent tint of the prothorax appears to be a 

 specific character ; but none of the specimens received (there being only one from each 

 locality) are in good condition.
