shoulder, the other near the apex ( 20 K The male differs in 

 being smaller, abdomen considerably smaller, prothorax with 

 black hairs much more conspicuous (on the female they are 

 sometimes entirely pale), elytra without sexual brands, and 

 tarsi somewhat longer. 



AUTOMOLUS MELANCHOLICUS, n. sp. 



Black; parts of tarsi somewhat reddish, antennae (club 

 excepted), and palpi flavous. Densely clothed with long ash en - 

 wliite hair, becoming darker on most of prothorax than 

 elsewhere, elytra with short and rather dense suberect, dark 

 pubescence, and with a few longer pale hairs. 



Head densely granulate-punctate; clypeus with sides and 

 apex incurved. Antennae apparently eight-, club three-jointed. 

 Prothorax rather strongly convex; with punctures as on head. 

 Elytra with suboblong, asperate punctures in irregular 

 (semidouble) rows, alternate interstices somewhat elevated. 

 Hind parts with dense and rather large but shallow punctures. 

 Front tibiae with two strong apical teeth, and a small one near 

 base, basal joint of hind tarsi very short. Length, 5-5 J mm.

In Blackburn's table would be associated with funereus 

 and striatipennis, from the former distinguished by its larger 

 size and hind tarsi, etc., and from the descripion of the latter 

 by the complete absence of abdominal scales. On funereus the 

 second joint of the hind tarsi is scarcely more than twice the 

 length of the first, and the length (excluding the claws) of 

 the fifth; on the present species the second joint is about 

 thrice the length of the first, and distinctly longer than the 

 fifth. The elytra are obscurely diluted with red about the 

 apex, they are without a conspicuous sexual brand on any of 

 the four specimens before me, but on two of them the summit 

 of the apical slope of each elytron has a shining interrupted 

 space that may be remnants of brands; the elytra of these 

 specimens, however, are quite as dark as those of the others, 

 and I can find no other distinctions likely to be sexual. 



AUTOMOLUS TRIDENTIFRONS, n. sp. 



PI. xxxvii., fig. 146. 

 Black ; elytra bright-castaneous, but base and suture 

 somewhat infuscated, antennae (club excepted), palpi, and 



(20) One of these was standing with specimens of depressus 

 in Blackburn's collection, but the punctures of the hind parts 

 readily distinguish it from the females of that species, apart 

 altogether from the sexual brands.
