70 THE CANADIAN ENTOMOLOGIST. 



Vertex very dark metallic green, evenly punctate. Frons above and 

 in front dark metallic greenish-blue, bordered below and at the sides by a 

 brownish-yellow band. The dark area, except a narrow median smooth 

 space at the bottom of the depression above, is rather coarsely and 

 irregularly pitted and covered by dark brown pile, while in the lighter 

 yellowish parts the pits are much finer and the pile, as elsewhere in the 

 face, paler. Anteclypeus and labrum pale yellow; postclypeus reddish- or 

 yellowish-brown, generally much darker in its middle part, but not forming 

 as distinct a dark band between the lighter parts above and below it as it 

 does in elongata, in which the middle portion and sometimes the entire 

 postclypeus forms a strong dark brown or black band between the paler 

 parts of the frons and anteclypeus. Labrum black. Occiput shining 

 reddish-brown, well rounded behind, bearing dense dark brown hairs 

 above, pale brownish ones behind. Posterior surface of head shining 

 black, with a submarginal dense row of long pale brownish hairs in line 

 with those of the occiput. 



Prothorax black, anterior lobe broadly margined with very pale yel- 

 low, posterior lobe dull metallic bronze-green, with pale brownish hairs, 

 convex behind. Meso- and metathorax dull metallic green, with blue or 

 violet-blue reflections, especially upon the epimera, covered with long pale 

 yellowish-brown hairs, except upon the antealar sinus, where the hairs are 

 dark brown, very short and denser than elsewhere. A few black hairs also 

 about the bases of both pairs of wings. A dull yellow mesepimeral band 

 usually 4-6 times as long as broad, and an elongate-oval metepimeral spot 

 of the same colour. These markings may be very inconspicuous in old 

 examples. Under parts of thorax pale yellowish brown. Legs black with 

 the following parts yellowish-brown : the coxae, or greater part of them, 

 first and upper surface of second trochanters, first femora, except near the 

 knees and sometimes the under surface, upper surface of second femora 

 except distally. 



Abdomen slightly more than 2^/^ times as long as head and thorax, 

 tumid at base, narrowest before middle of 3, thence expanding to apex of 

 5, where width about equals base of 2, sides of 6 parallel, remaining 

 segments very gradually narrowing. Colour dull dark bronzy-green, 

 covered with fine short pale brownish hairs ; sides of 2 and base of 3 

 shining dark brown with conspicuous pale brownish hairs, genital lobe 

 black. A brownish yellow band on lateral surface of 2 in its lower half, 

 passing just above genital lobe, where it is generally constricted and often
