of Mr. Douglas and my own, yet it is not impossible that it may be 

 found mixed up witL. the two species named above in the cabinets of 

 other collectors. 



Crown testaceous, with an arcuate black streak at the anterior margin, and a fre- 

 quently interrupted transverse streak of the same colour in a line with the 

 anterior margin of the eyes ; frequently these characters are almost obsolete. 

 Face black, with 7 — 8 fine transverse, curved, yellowish lines on each side, the 

 two next the apex generally appearing as spots ; down the centre a nan-ow yellow 

 line, frequently wanting. Clypeus black, with a broadish yellow margin. LorfB 

 yellow, more or less broadly margined with black. Elytra as long as, or slightly 

 shorter than, the abdomen, testaceous. Clavus : on one or both sides narrowly 

 margined with brown, and frequently broken up into spots. Corium : next the 

 claval suture with a brown streak ; all the areas more or less brown ; apical 

 areas generally brown ; sometimes the entire disc is pitchy-brown, leaving the 

 nerves here and there narrowly testaceous. Thighs : 1st pair yellow, with a 

 broad black ring at the base, and another narrow one before the apex ; these are 

 very often represented by two spots on the lower margin, or are entirely 

 absent. Length, 1^ — If lines 4. soedidtjs, Zett. (cow/«sm5, Kirschb.). 



The characters on the head are somewhat like those of A. grisescens, 

 but their position is different, whilst those on the elytra more resemble 

 A. ohsolcfus, a species much larger than the one just described. 



JEltftra testaceous ; nerves on both sides, and frequently the areas, more or less irror- 

 ated with fuscous-black. Clavus : apex narrowly, and apex of the nerves white. 



Crown with a very narrow black central line extending from the base to about in a 

 line with the anterior margin of the eyes ; near the base, and nearer to the eyes 

 than the centre, a small black spot ; in front two others slightly larger and close 

 together ; round the half of the ocelli next the eyes is a broad black border to 

 which is joined an elongate black patch running somewhat obliquely towards 

 the centre of the basal margin. Face^frons with a lunate black patch on either 

 side, below which are seven or eight transverse black streaks. Thighs : first 

 and second pairs with the apex narrowly and two rings, the basal one broadest, 



black 5. lEBOBATUS, w. sp. 



Extremely like A. ohscurellus, and probabh^ may be mixed up "n"ith 

 this species in collections, but the narrower head and characters on it, 

 and the elytra, will lead to its identity. 



Section B. 



Distance between the inner margin of the eyes at the base twice as 



great as the length down the centre. 



a. Anterior margin distinctly rounded ; angle somewhat obtuse. 



g. Crown black, with a narrow yellow arcuate hne on the anterior margin, slightly 

 widest in the middle, and extending from eye to eye j basal margin with two
