quam latius. 



Capvt profunde imniersum, deplanatum, ter fere latius quam 

 longius. 



Ocnli minutissimi. 



Ayitenncc sub capite celatEe, antennge primi paris iis secundi paris 

 longitudine superantes, octo-articulatEe. 



Processus segmenti primi i)ereii longissimi, caput fere longitu- 

 dine ^quantes. Segmentum quintum aliis latius. Anguli postici seg- 

 mentorum quattuor priorum truncati, sequentium rotundati. 



Epimera latera segmentorum non explentia. Epimera segmenti 

 secundi tertiique recta, non auriculiformia. 



Pedes piereii septimi paris longissimi. femoribus latissimis. 



Pleon curtum, angustum, segmen to primo non obtecto. 



Urvs quam pleon longior ac latior, fere rectangularis, angulis
