ANHAMMUS ABERRANS. 147 



Dalenii. As it is however a Monohammid ') with declivous 

 mesosternum (neither produced nor tuberculated), with per- 

 pendicular (not transverse) lower lobes of the eyes, and 

 with the prothorax armed at the sides before the middle 

 (although not so far forwards as in Dalenii) with a strongly 

 developed acute spine , whereas the antennae are neither 

 fringed nor ciliated and the femora and tibiae are not 

 compressed , I do not hesitate to bring this species as a 

 somewhat aberrant one to the genus Anhammus Thoms. 



Length 38 mm., that of the antennae 53 mm.; breadth 

 at the shoulders 6 mm. — Black , with the palpi (the 

 apical half of the last joint excepted), the 3rd and follow- 

 ing joints of the antennae, the tibiae and the abdomen 

 chestnut-brown , the apex of the tibiae blackish. Covered 

 with a close dark fulvous pubescence, especially on the 

 under surface ; on the posterior portion of the head it is 

 coal-black; on the tarsi the pubescence has a somewhat 

 greyish tinge , and on the apex of the 4th-8th as well 

 as on the entire 9th-llth joints of the antennae (except 

 on the extreme tip of the apical joint where it is ashy) 

 the pubescence is blackish. Moreover the antennae and 

 tibiae have a few scattered pale coloured erect hairs. The 

 lateral spines and the granules of the thorax, the middle 

 of the scutellum , and the granules and surrounding parts 

 of the punctures of the elytra are destitute of pubescence ; 

 the naked portions round the punctures irregularly con- 

 fluent. 



The head slightly rugose in front and sparingly punct- 

 ured; a slightly impressed line extending from the ante- 

 rior margin of the clypeus up to the prothorax. The scape 

 of the antennae densely covered with very minute punct- 

 ures intermixed with larger ones. 



The prothorax with one anterior and two posterior not 

 very distinct transverse grooves; the disk between the
