Mas capitc postice laminate lamina emarginata angulis pro- 



ductis.

 Long. 8| lin., lat. 4 lin. 



The upper surface is black ; the head is smooth in the male 

 and sUghtly wrinkled in the female, with the clypeus in the male 

 triangular, somewhat truncated and recurved at the apex, and 

 slightly emarginate, and in the female rather rounded ; the back 

 part of the head is produced into a plate with pointed angles, 

 and somewhat emarginate in the middle, in the female the head 

 is less produced and the angles less pointed. The thorax is 

 smooth and perpendicular in front, taking almost the shape 

 of the back part of the head which seems to fit into it, the 

 greater portion of the rest of the thorax is punctured, with the 

 medial Hne distinctly but not deeply marked. The elytra are 

 striated with a row of minute punctures in each stria. The 

 pygidium is triangular and finely punctured. The under surface 

 is black, punctured, and covered with tufts of reddish hair.

Long. 5^ lin., lat. 3 lin. 

 This insect is of a somewhat shining black colour. The 

 clypeus is rounded with the apex somewhat pointed and reflexed, 

 the head is produced behind into a plate with lengthened re- 

 curved angles and a deep emargination in the middle. The 

 thorax is retuse in front, with a broad almost emarginate tubercle, 

 crowning the retuse portion in the middle, and with a small 

 pointed tubercle on each side of it ; the anterior part of the 

 thorax seems in this species, as in that last described, to take 

 the shape of the produced back part of the head ; the medial 

 line is not well marked. The elytra are marked with stria?, 

 having a row of small punctures in each. The under surface 

 and legs are of a less deep black than the upper parts of the 

 insect, and are thinly clothed with reddish hair.
