T. difficile^ sp. no v. Elongato-ovale ; obscure nigro- et griseo- 

 hirtum ; nigrum, antennarum articulis 3-7 tarsisque rufis ; 

 obscure subcrasse (prothoracis disco multo minus crasse) 

 punctulatum ; sulcis antennariis minus profundis, postice 

 clausis, lateribus subparallelis. 

 Mas. (?) Antennarum clava 4-articulata, quam articuli 1-7 

 conjuncti baud longiori, articulis 3-7 p^rvis, clava ovali, 

 hujus articulo I'' parvo, 2° et 3" sat sequalibus, 5° quam 

 4''^ multo longiori baud angustiori. Long., If 1. ; lat., -^-^ 1. 

 Tbe prosternal sulci in this species differ in form from those 

 of the preceding ; they are a little wider and less deep, and in- 

 stead of the sides of each sulcus converging from its open base 

 (on the front margin of the prosternum) continuously till they 

 meet at the hind angle of the prosternum, they run almost 

 parallel to each other for about half their length, and converge 

 only in their hind portion. 



The 3rd and following joints of the antenna? are very closely 

 crowded together, and consequently difficult to count ; it is only 

 by examination under a high-power that I have satislied myself 

 as to their number. As in some of the preceding species, the ap- 

 portionment of joints to the stem and club is no easy matter. At 

 a glance, the club seems to be 3-articulate, but on examination 

 the 8th joint seems clearly to go with those of the club, being 

 evidently much wider than the preceding — l^ut I cannot look 

 upon the 7th joint as a part of the club. The robust apical joint 

 (not at all narrower than the penultimate) gives the antennae a 

 very distinct appearance. The puncturation of the elytra also is 

 coarser than usual.

 T. Madeayi, sp. nov. Late ovale, postice angustatum ; nigro- 

 hirtum ; nigrum, antennis tarsis et elytris (macula magna 

 communi discoidali nigra excepta) rufis ; obscure vix crebre 

 (prothoracis disco magis subtiliter sat sparsim) punctulatum ; 

 sulcis antennariis profundis bene determinatis, triangulari- 

 bus, postice clausis. 

 Mas. Antennarum articulis 4-10 pectiniformibus, 3^ minuto, 



11° compresso-lamelliformi. 

 Femina. Antennarum articulis 5-10 leviter serratis, 11° ovali 



apice acuminato. Long., 1^— 1|- 1. ; lat., 4 1. — 1 1. 

 The pectinations of the antennte of the male increase in length 

 to the seventh joint, those of the seventh, eighth, and ninth being 

 about equal inter se, each of them about as long as the basal four 

 joints together of the front tarsi, that of the tenth joint is a little 

 shorter. The apical joint is a compressed somewhat piriform 

 lamella scarcely so long as the tenth joint.
