98 PAMPHILIUS SYLVARUM. 



II. THE GROUP or SYLVARUM. 



Head and thorax pale ochreous, with numerous black spots; 

 metathorax and abdomen black above. Antenna3 19-jointed, 

 shorter than abdomen, third joint a little longer than two 

 following united. Head broader than thorax. Lateral sutures 

 on vertex very deep and broad, reaching to the antenna ; trans- 

 verse suture not so broad nor so deep but still clearly denned. 



This is a group of small extent. It is well defined 

 by the broad and flat head, short antennae, and by the 

 pale ochreous head and thorax, which bear more black 

 markings than any other species, and by the fulvous 

 tinted wings. The species appears to be rare.
