of the Famihj Lamiidoa. 279 



Legs of equal length ; the femora sublinear ; middle tibiae 

 without the slightest trace of tubercle or notch. 



Sternal processes simple and rather narrow ; the anterior 

 coxal cavities distinctly open behind *. 



This last character, in conjunction with the entire median 

 tibige and the rather narrow sternal processes, will sufficiently 

 distinguish the genus amongst the group of the Monoham- 

 mids ; there is only one other genus of the group (^Eukeniopsis, 

 described in the present paper) in which the anterior coxal 

 cavities are open behind ; from this genus it is very distinct. 



May be placed after Mecyntppus and Goes. 



Haploihrix simplex^ n. sp. (PI. XVI. figs. 5 & 5 a.) 



Omnino dense brunneo-griseo pubeseens ; antennis concoloribus, 

 scapi cicatrice pubesceute ; protliorace supra aequah', spinis lateral- 

 ibus ad basin angustis ; elytris elongatis, lateribus subparallelis, 

 apicibus rotundatis ; segmento abdominis quinto ( c? ) ad apicem 

 media fovea. 



Long. 26 mm., lat. 8 mm. 



Uab. Siam. 



The whole of the body, the legs, and antennae covered with 

 a unicolorous, dense, drab-grey pubescence. The head ira- 

 punctate. The prothorax smooth above, the lateral spines 

 rather narrow at the base ; the elytra very minutely punc- 

 tured, the punctures scarcely visible through the pubescence. 

 The legs all very similar in size and form. The last seg- 

 ment of the abdomen in the male is slightly emarginate at 

 the apex, and has, just in front of this emargination, a deep 

 and somewhat transverse depression. 



Pharsalia albojjlagiata, n. sp. 



P. vinosa affinis, sed major ; protborace omnino oehraceo, impuuctato, 

 antice et postice transverse sulcato ; elytris lateribus ante medium 



* lu the treatment of the Lamiid^ this character of the coxal cavities, 

 so useful in other families, has been hitherto neglected. Lacordaire, 

 indeed, in his iutroductor}' account of the family, states that the anterior 

 coxal cavities are coustantly closed behind. 1 have shown that there are 

 exceptions to this ride in the Monohammiis-growp. In the Batocera- 

 group of Lacordaire the character is of greater importance, for by means 

 of it the genera may conveniently be subdivided into two groups, in one 

 of which the coxal cavities are open behind, in the other closed. The 

 former includes Batucera and all the genera which most closely resemble 

 Butocera in their organization, \iz. Apriona, Mcyacriodas, and liusen- 

 beryia.
