siniiDtis posterior margin merging with the narrowly blunt posterior 

 margin. The cervical grooves are very deep and convergent, and 

 reach the midlength of the scutumj thence they continue as very 

 shallow, divergent grooves extending to or almost to the posterior 

 margin. Lateral grooves as such are absent; their place is marked 

 by three to seven very large, deep ptmctations that may be either 

 free or in a shallow depression; the lateral field beyond these 

 grooves is more or less abruptly raised. The scutum is slightly 

 depressed between the lateral punctations and the shallow exten- 

 sions of the cervical grooves, but its intense black surface is 

 otherwise marked by only four to seven large, deep, scattered 

 punctations. The basis capituli is three times as wide as long 

 and widest at its midlength; the porose areas are oval, vertical 

 (not tilted), about twice as long as wide, deep, separated by a 

 distance of one and a half times their own length, and extend 

 from alioDst the posterior margin to just past the midlength of 

 the basis capituli. Ventrally, it is important to note that 

 coxa I is not deeply divided but that its posterior margin bears 

 two robust spurs; the broadly triangular internal spur is not 

 quite so long as the more narrowly triangular external spur and 

 the division between these two spurs is equi triangular with the 

 internal spur.
