Head and thorax pale ochreouB, with numerous black spots ; metathorax and 

 abdomen black above. Antennse IQ-jointed, shorter than the abdomen, 3rd joint a 

 little longer than the following two together ; head broader than thorax ; lateral 

 sutures on vertex very deep and broad, reaching to the antennae, transverse suture 

 not so broad nor so deep, but still clearly defined. 



This is a group of small extent, but well defined bj the broad 

 and flat head, short antenna ; by the pale ochreous head and thorax, 

 which bear more black markings than in any other species ; and by the 

 fulvous tinted wings.

Body orange, tho^rax and apex of abdomen black ; wings yellowish-hyaline, with 

 a small fascia in the middle, the stigma testaceous. Antennae long, 23— 28-iointed, 

 3rd joint a little longer than the two following together ; face slightly keeled ; scu- 

 tellum convex in the centre. 



5. Pamphilius betul^, L. 



The group of sylyaticus.

 and legs yellow, black at the base ; 23 — 31-jointed, the 3rd joint not much longer

 the middle of the front. Head between the antennae slightly carinated. Antennae 

 21-jointed, yellow at the base, the rest testaceous, 3rd joint not much longer than 

 the 4th. 



The yellow and black stigma, the antennae yellow at base, and
