 brown at the base, with uncolored tip; eye indistinct with one long hair, and near 

 the posterior margin a second long hair ; temples rounding, with four long hairs, the 

 three in the temporal angle are pustulated, occipital margin weakly convex ; ground 

 color of head chestnut-brown, signature distinct, anterior margin deeply concave, 

 with a slight lateral constriction near the anterior angles, lateral margins rapidly 

 diverging, forming sharp posterior angles, the posterior margin extending backward 

 in a long, acute angle beyond the mandibles ; antennal bands interrupted at the suture,
