 the second scalpal and extreme base of the first flagellar segment a little red-

 evenly and roundly notched, the lateral angles produced into conspicuous 

 chitinized horns ; a tiny median notch on the caudal margin, and a pale yel- 

 lowish median line extending the length of the tergite. Ninth pleurite incom-
