Astathes and allied Genera of Longicom Coleoptera. 39 



anteriorly with a deep horizontally directed pit. Costae of elytra 

 usually more or less obsolete and never very acute. 



1. Astathes perplexa. 



Astathes perplexa, Newm., The Entomologist, i, p. 299 



(1842). 

 Astathes illigeri, Thorns., Syst. Ceramb., App., p. 558. 



Entirely testaceous with the exception of the last six or seven 

 joints of the antennas which are infuscate. Head somewhat strongly, 

 but not very thickly, punctured in front, feebly and sparsely 

 punctured on the crown. Pronotum rather feebly and sparingly 

 punctured on the sides of the central elevation. Elytra sparingly 

 punctured, the punctures being rather large, and arranged, some in 

 rows the others more irregularly, on the basal half ; with numerous 

 very minute setigerous pits in addition, the setae arising from these 

 being of a tawny colour. In the female type the elytra are pale 

 yellowish-testaceous, contrasting with the more rufous tint of the 

 head and prothorax, and the costse are almost obsolete. In three 

 other specimens, the elytra are nearly concolorous with the head 

 and pronotum, and in two of these the costse are distinctly, though 

 not strongly, raised. In the type of illigeri, Thorns., the elytra are 

 rufous in tint, exhibiting slight purplish reflexions in certain lights, 

 and the costae are distinctly raised.

2. Astathes mniszechi. 



Astathes perplexa, var. y, Newm., The Entomol., i, p. 299 



(1842). 

 Tetraophthalmus mniszechi, Thorns., Archiv. Ent., i, p. 50 

 (1857). 

 Very closely allied to A. perplexa, Newm., the only character 

 serving to distinguish it being the somewhat feebler puncturation 

 of the front of the head, and the presence of a very distinct, but 

 rather small, violet spot behind the middle of each elytron. The 

 elytra are usually of a rufo-testaceous colour, exhibiting slight 

 purplish reflexions in certain lights ; but in one specimen in M. 

 Oberthiir's collection, the general colour is pale yellow or stra- 

 mineous, with the antennae infuscate towards the apex, and the 

 violet spot on each elytron rather larger and more conspicuous than 

 in the type .
