 posterior median area on the median segment ; a large 

 ■oblique mark, rounded at the apex, on the lower part of the

 and complete ; the posterior median is widely distant from the 

 base, is longer than broad, rounded at the base, and slightly 

 narrowed towards the apex. The greater part of the coxae
