$. Body long, oval and narrowed anteriorly. Dorsal shield (fig. 1) long and rather

 posteriorly and pointed at the end. Surface of shield almost smooth, but it is 

 slightly roughened by a faint reticulate sculpturing. Two pairs of hairs are placed 

 close together in the middle of the front end of it, the posterior pair being long. 

 Besides these two anterior pairs, there are seven inner pairs of hairs on the shield,
