punctures) in the fifth (counting the short scutellar one) row 

 of punctures at the posthunieral depression, and sometimes 

 one in the fourth as well. Both species vary considerably in 

 colour, but whereas on hypochalcea each elytron (when not 

 uniformly coloured) has a blue transverse vitta occupying the 

 posthunieral depression, and no other ; on the present species 

 there is a wider blue vitta there, and an oblique postmedian 

 one as well. But the four hind tibiae of the male readily 

 distinguish the species from hypochalcea and from all other 

 described ones of the genus. 



The most abundant form has the upper-surface mostly 

 of a fiery-red or golden, with parts of the clypeus and a 

 median line on head, an irregular part of base, and the 

 extreme lateral and apical margins of prothorax, scutellum, 

 suture, the two vittae on each elytron (the first transverse 

 and at the basal third, the second oblique and from just 

 beyond the middle to near the apex) purple, but where the 

 two colours join the surface is more or less of a golden-green ; 

 the under-surface and legs are more or less golden-green or 

 ■fiery, overlaying blue or purple. But many specimens are 

 more or less brassy-green, with purple markings as noted, 

 and with the under-surface and legs almost entirely purple. 



Var. 1. Purple, with a greenish gloss replacing the 

 fiery-golden colour of the upper-surface, but head (labrum 

 excepted) and under-surface entirely purple. One male of 

 this form with the green but feebly indicated was sent by 

 Mr. Dodd as having been taken in cop. with a normal female : 

 other specimens have the green so faintly indicated that they 

 might have been regarded as belonging to the following 

 variety. 



Var. 2. Entirely purple (except for the labrum, anten- 

 nae, and palpi). This form has a deceptive resemblance to 

 Stethomela flavicornis, but the prosternum is very different 

 and antennae with only some of the basal joints partly 

 ■pale, etc. 



Cyclomela nit ida, Baly. 



On the form of this species with brassy elytra the tibiae 

 are usually uniformly red, on the form with coppery-green 

 elytra they are usually black at the base ; one specimen before 

 me has purplish-blue elytra, with no black on the tibiae ; 

 another with brassy elytra has knees black at the base and 

 the prothorax (except at the sides) deeply infuscated. 



Cyclomela nigricollis, n. sp. 

 Head, basal joints of antennae (the others black), palpi, 

 and legs^ reddish-flavous ; prothorax, scutellum, and under- 

 surface black, elytra metallic-green.
