50 COLEOPTERA. 



The present insect ajDpears to belong to the genus Bryopo- 

 rusy on account of the structure of its maxillary palpi, the 

 apical joint of which is short and moderately stout, of an 

 elongate conical form, and only a trifle shorter than the 

 preceding joint. In the typical Boletohii the palpi are 

 elongate and slender, but Mr. Bold's insect approaches very 

 nearly in these members to the form exhibited by the section 

 Megacronus of Stephens, and moie especially to Bryoporus 

 rvfus; it is, however, smaller and narrower than the latter 

 species, with shorter and stouter antennae, the only punctures 

 on the elytra being about five (somewhat indistinct) in the 

 ordinary discoidal and sutural striae. 



It also in size, form and proportions, bears a great resem- 

 blance to Mycetoporus splendenSj but differs from that insect 

 in the greater development of the terminal joint of the max- 

 illary palpi, in the antenna being rather stouter, with the 

 basal joints (especially the 2nd, 4th, and 5th) shorter, the 

 punctures on the striae of the elytra fewer and less distinct, 

 and the abdomen less thickly punctured, the basal segment 

 being nearly impunctate. 



In colour it is rufo-testaceous, with the head rufo-piceous, 

 the abdomen pale castaneous, and the antennae, except the 

 three basal joints, black.
