 thorax reddish, the deflexed lateral lobes yellow, the back on both sides 

 with an oblique black spot.

 ochreous humeral fascia, terminated in front by a small streak-like spot, 

 and behind by two ordinary black spots.

 the elevated keel on the thorax testaceous, with a white patch on both 

 sides, terminated anteriorly and posteriorly as in var. y. 



Var. e. Ac. cristatum. Zetter. O. S. 120. — Griseous-brown, with the carinas 

 on the front and vertex, and the central one of the thorax yellow ; the 

 thorax spotted as usual.

 the crown and central thoracic keel yellow, the disc of the thorax with an

Var. 0. Ac. obscurum. Zetter. O. S. 125. — Brown, or dusky-black; thorax, on 

 both sides, with an oblique black spot, with a triangular white one towards

 thorax on each side anteriorly with a black incurved crescent-like line, and 

 behind this the ordinary spot, having a slight tooth behind, and thus
