pubescent : head hardly broader than the chest : eyes and eyelets 

 red : feelers black, compact, rather stout, nearly filiform, clothed with 

 yellow down, nearly as long as the chest ; first joint long, slender, 

 green ; second cup-shaped, shining, not pubescent ; third and fourth 

 extremely minute ; fifth and following joints nearly equal in length ; 

 club long-conical, rather more than twice the length of the preceding 

 joint : chest long-elliptical : fore-chest rather long, narrower and 

 rounded in front ; its length rather more than half its breadth : shield 

 of the mid-chest very long ; sutures of the parapsides very strongly 

 marked ; axillae parted by rather less than one-fourth of the breadth 

 of the chest ; scutcheon nearly rhomboidal, almost smooth at the tip, 

 where it forms a ridge and thence declines very abruptly ; hind-scut- 

 cheon short but distinct : hind-chest of moderate size, obconical. de- 

 clining, nearly smooth : petiole very short : abdomen convex, spindle- 

 shaped, smooth, shining, bright purple, rather hairy, bright blue at 

 the base, narrower than the chest and but little more than half its 

 length ; metapodeon occupying about one-third of the back, concave 

 at the base ; its hind-border convex, and passing over the back of 

 the octoon which is short ; ennaton longer than the octoon ; decaton 

 longer than the ennaton ; the three following segments shorter : 

 sexual parts piceous, rather long : legs yellow ; hips, thighs and hind- 

 shanks green ; trochanters and knees tawny ; tips of feet brown : 

 wings colourless, pubescent ; veins brown ; ulna full half the length 

 of the humerus ; radius rather more than one-third of the length of 

 the ulna ; cubitus very short, not more than one-third of the length 

 of the radius ; brand very small, forked, emitting a short branch. 

 Length of the body 1^ line ; of the wings 3 lines.

Head finely shagreened, bright green, purplish blue on the crown, 

 broader than the chest : eyes and eyelets red : feelers black, clavate, 

 not longer than the chest ; first joint long, slender ; second cup- 

 shaped ; third and fourth very small ; the following from the fifth to 

 the tenth successively increasing in breadth, but hardly decreasing in 

 length ; club conical, broader than the tenth joint and about thrice 

 its length : chest blue, nearly elliptical, very convex, shining, trans- 

 versely rugulose, but appearing almost smooth, the marks being very 

 slight : fore-chest very short ; its length not more than one-eighth of 

 its breadth : shield of the mid-chest large, roughly punctured, much 

 broader than long ; sutures of the parapsides indistinct ; scutcheon 

 obconical above, having a rim behind whence it declines abruptly 

 and forms a right angle ; axillae parted by nearly one-third of the 

 breadth of the chest : hind-chest transverse, rough, very short : 

 petiole extremely short : abdomen long, obconical, convex, shining, 

 rather hairy, especially towards the tip, finely punctured, denticulate 

 and with rows of large punctures across each segment, smooth at
