322 FAUNA HAWAIIENSIS 



Dark blue ; the antennae, apex of fore femora, apical third of middle and apical 

 half of hind femora, the tibiae and tarsi yellowish testaceous, base of four anterior tibiae 

 fuscous ; club of antennae darker than scape ; abdomen more or less green. Wings 

 hyaline, nervures testaceous. Head covered with large, distinctly separated punctures ; 

 thorax more closely punctured, the punctures being also smaller than those on the head ; 

 scutellum closely and more finely punctured than the metanotum ; abdomen shining, 

 impunctate. Head and mesothorax finely and sparsely pilose ; scutellum densely 

 pilose. Abdomen glabrous. 



Scape of antennae longer than the flagellum, the flagellum 7-jointed, the first six 

 broader than long, becoming gradually broader until the sixth is double as wide as long; 

 last joint (forming a club) longer than the preceding six ; the apex produced laterally, 

 the elongation forming about one-fourth of the total length, and half the thickness of 

 the central part ; the club becomes gradually thickened towards the apex. The 

 flagellum is covered with longish stiff hairs, directed towards the apex. Head broad, 

 rather large ; eyes large, converging above ; ocelli in a wide triangle, widely separated, 

 the upper two nearly touching the eyes ; occiput concave. Face deeply excavated, the 

 excavation reaching laterally to the mouth ; epistoma projecting, broadly keeled. 

 Thorax large, broad, without sutures ; scutellum large ; metathorax small. Abdomen 

 shorter than the thorax, the apex narrowed, transverse. Wings scarcely as long as the 

 body ; cubitus more than double the length of the ulna, which is very short ; radius 

 absent ; edge of wing shortly ciliated. The cubitus does not reach to the middle of the 

 wing. Hind tibiae almost one-spurred, the inner being a mere stump. 



The above-described species is certainly not an Encyi-ttis as now understood. I 

 cannot make it fit into any of the genera as defined by Mayr and Foerster ; but having 

 only a single example (a male), I do not care to found a new genus for its reception. 

 The sculpture of the head and thorax is pretty much as in BothriotJiorax. (Cameron.) 



There is a BothriotJiorax insularis Howard, described later from the West Indies; 

 it may be known hereafter as B. howardii.
