Hi Chris &amp; All,&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; Sept 15, 2005<br>
&nbsp;&nbsp;&nbsp; I collected a small beetle on Sept 5 (1208) that had two prominent features;
very enlarged hind coxae and a combination of features that did not fit any
family that I could think of. So your mention of 'plate-thigh' solved that
riddle, at least to family level.<br>
  <br>
&nbsp;&nbsp;&nbsp; The key in Amer. Beetles conflicts with the figures so one must navigate
by guesswork and doing so has <i>Nycteus</i> as the endpoint. <br>
&nbsp;5.meso- &amp; 5.meta-tarsomere longer than 4. respectively;<br>
procoxae transverse;<br>
5 visible sternites with trace of 6th;<br>
sutural stria impressed in apical 3/5 but other stria not hinted;<br>
epipleura widened in basal 1/3;<br>
head hidden from above and narrowed abruptly distal to eyes;<br>
antenna long and gradually widened as in Fig 1.35 for <i>E. terminalis</i>
 LeConte.<br>
  <br>
&nbsp;&nbsp;&nbsp; Does this fit <i>N. punctulatus</i> (LeConte) or any <i>Nycteus</i> ?<br>
  <br>
Yours truly, Dave Webster, Kentville<br>
