2 . Length 2"2 millim. ; expanse 3"4 millim. ; greatest width 

 of fore wing 0"39 millim. Pace and vertex smooth, well rounded, 

 with small sparse round punctures ; pronotum and mesoscutum 

 regularly scaly with appressed hairs ; mesoscutellum very finely 

 granulate, but shining ; abdomen very faintly transversely striate, 

 longer than head and thorax together ; all pleura and hind coxae 

 hairless, shining, irregularly shagreeued, the coxae more coarsely 

 than the pleura ; middle and hind femora somewhat obliquely 

 longitudinally shagreened, middle femora with sparse appressed 

 hairs. Eunicle-joints 1, 2, 3 of the antennae subequal in length 

 and width, all wider and longer than pedicel, but somewhat 

 shorter than club, which is slightly flattened and acuminate ; 

 first tarsal joint of fore legs about half as long as tibia; corre- 

 sponding joint of middle and hind legs as long as tibia. Two 

 dark brown subparallel longitudinal raised lines on dorsum of 

 fore and middle tibiae ; a series of five or six irregular longitudinal 

 closed cells formed by similar dark brown lines on hind tibise * ; 

 middle tibial spur about | as long as first tarsal joint. Greneral 

 colour dark metallic gi-eeuish-blue ; antennae dark brown, scape 

 yellowish beneath ; minute tip of scutellum yellowish white ; 



* These dark brown or black raised lines, the peculiar arrangement of which 

 on the hind tibiae affords svicb a good character in this genus, are, when examined 

 under a high power, seen to be rows of acute appressed spines situated so closely 

 together that their bases touch.
