crude pupal chamber near the exterior part of the trunk where 

 the old leaf axils are located. It was creamy white when 

 found, but upon being placed in alcohol, the latter acted as a fix- 

 ative, since the pupa changed to light brown and the spots on the 

 elytra became distinctly visible (Plate I, fig. 10). In general 

 appearance the pupa is rather elongate. Anterior margin of 

 clypeus and sides of the head beset with a few bristles. The 

 meso- and metathoracical segments dorsally, somewhat laterad, 

 beset with two thornlike tubercles, and the abdominal segments 

 dorsally beset with a series of fleshy tubercles bearing a few 

 short bristles. Anal segment dorsolateral with a more pro- 

 jecting tubercle and several smaller ones, each bearing a long 

 bristle. 



The beetles feed on the leaves of the fern, starting at the 

 edges and devouring an oval piece about 2 centimeters long. 

 Pachyrrhynchus venustus has the same common habit as have 

 most species of Pachyrrhynchus. The beetles in climbing about 

 and being approached at first try to hide by crawling on the 

 underside of the leaf or on the reverse side of the stem, but if 

 approached closely they instantly drop to the ground and remain 

 motionless for some time. In the dense undergrowth it is very 

 difficult to rediscover the beetle when it has dropped. The spots 

 on the elytra of P. venustus Pasc. vary in number from 20 to 24 

 and are very pale lilac-colored. 



On the leaves of the same fern I also found the interesting 

 Buprestidse, Endelus bakeri Kerrem.
