240 THE INSECTS OF GAYNDAII, 



terstices elevated, — and marked with a large round spot near the 

 base, a fascia above the middle extending on the sides to near 

 the humeral angle and not reaching the suture, another fascia 

 behind the middle also not reaching the suture, and a small round 

 spot near the apex, all of a golden yellow. Under side of body 

 brassy green, with purplish spots on the abdomen. Legs green, 

 with the apex of the tibioa and the tarsi yellow. 



422. — Melobasis azukeipennis. n. sp. 



Length 4| lines. 



Head blue, densely clothed with golden hair. Thorax of a 

 fiery copper colour and punctate, densely on the sides, thinly in 

 the middle. Elytra blue, nitid, sti'iato-punctate — the interstices 

 smooth, — and strongly serrated at and near the apex. Body 

 beneath brassy green, changing to steel blue towards the apex of 

 the abdomen. In the female the under surface and legs are 

 entirely blue. 



I find specimens from Port Denison of this beautiful species 

 in my collection labelled M. azureipennis La Ferte, but I have not 

 been able to find any notice of such an insect having been 

 described. 



423. — Melobasis costata. n. sp. 



Length 6| lines. 

 Elongate, bronze green, subopaque, densely and finely punc- 

 tate. Head clothed with whitish pubescence. Thorax less 

 densely punctate than the rest of the body, with a minute fovea 

 in the centre of the base, and with an almost imperceptible 

 smooth space marking the median line. Scutellum small, rounded, 

 green, smooth, and nitid. Elytra slightly serrated towards the 

 apex, and marked with three elevated smooth lines, the inner 

 one largest and nearly reaching the apex, the second less dis- 

 tinct but nearly as long, the third least distinct and much shorter. 

 There is also a short costa near the scutellum extending from 

 the base to the suture at about one thii'd of its length. Legs 

 coppery red, tarsi cyaneous.
