 griseous or ochreous ; thorax with two more or less distinct black spots, 

 placed obliquely a little behind the shoulders; legs reddish-testaceous, or 

 griseous, a little clouded with brown occasionally. 



No two examples are found precisely alike: the following varieties have been 

 described as distinct by Zetterstedt and others : — 



Var. /3. Ac. laterale. Zetter. O. S. 118. — Fuscous, with the head dusky, 

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

 with an oblique black spot. 



Var. y. Ac. ephippium. Zetter. O. S. 118. — Reddish, the thorax with a broad 

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

 and behind by two ordinary black spots. 



Var. S. Ac. binotatum. Zetter. O. S. 119. — Variegated with ashy and brown, 

 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 carinae 

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

 thorax spotted as usual. 



Var. Z. Ac. vittatum. Zetter. O. S. 121. — Fuscous, variegated with griseous, 

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

 abbreviated waved longitudinal black line, on each side. 



Var. t). Ac. zonatum. Zetter. O. S. 124. — Dusky-black, with a broad waved 

 white band on the thorax, in which are two very obscure dusky spots, 

 and a flexuous fascia on the outer edge of the femora whitish. 



Var. 6. 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 

 the head ; the hinder femora with a pale streak without. 



Var. t. Ac. ochraceum. Zetter. O. S. 124. — Fuscous, with the legs variegated 

 with testaceous; above ochreous ; the thorax with the deflexed lobes brown 

 or pitchy, the disc on each side with a lateral triangular black spot. 



Var. K. Ac. hieroglyphicum. Zetier. O. S. 125.— Fuscous, spotted with 

 testaceous ; thorax with four rather distinct black ziczac streaks and dots, 

 placed irregularly ; the deflexed lateral lobes with the apex testaceous. 



Var. X. Ac. scriptum. Zetter. O. S. 126. — Fuscous or ashy; back of the 

 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 

 becoming bifid; on the hinder portion are some brown streaks and spots 

 flisposed somewhat in lines.
