allied to Masynates of Karsch, but differing from it in having a more appressed head 

 and less convex vertex and broadly convex and prominent fastigium, were found near

 cinereous with a broad black median stripe on the vertex and the upper half of the 

 lateral lobes of the pronotum and on the abdomen. The length is only 9 mm.

 The first generation of the insect appears as early as the end of February. Pupae 

 have been found in the middle of July. Larval development is slow.
