near the scutellum, an undulating fascia a trifle behind the middle, descending at the 

 suture, and a second fascia just before the apex. The terminal segment of the abdo- 

 men of the male is excised at the apex, the excision being straight in the middle, with 

 its sides oblique ; on the outer side are four not very large triangular teeth placed very 

 obliquely (fig. 19). 



35. Pachyschelus elegans. (Tab. VIII. fig. 20.) 



Ovatus, convexus, nitidus, supra obscure cupreo-purpureus ; thorace creberrime reticulato-striolato, lateribus 

 parce pubescentibus ; elytris postice arcuatim angustatis, basi punctatis, ante apicem fascia communi 

 curvata alba ornatis.

This species somewhat resembles P. bifasciatus, but is a little broader, without 

 angulations at the sides, a trifle broader just before the middle than at the base, and 

 then arcuately narrowed to the apex ; the apical half is very delicately punctured, 

 appearing almost smooth ; there is a little whitish pubescence near the scutellum, a 

 small spot near the suture, about the middle, and a distinct curved fascia commencing 

 at the margin behind the middle and descending to one-third from the apex at the 

 suture. The terminal segment of the abdomen of the male has at the apex four teeth 

 on each side (separated by a wide triangular space) — first a very small one, then a large 

 terminal one, a rather smaller one on the outer side at a lower level, and the fourth 

 still smaller and lower down (fig. 20). 



36. Pachyschelus azureus. (Tab. vni. fig. 21.) 



Supra azureus, nitidus ; capite thoraceque aeneo-tinctis ; elytris postice angustatis, punctatis, ante apicem guttis 



duabus albis ornatis.

This and the following species, which closely resemble each other, vary somewhat in 

 tint, the elytra being usually bright blue (sometimes slightly tinted with golden-green), 

 and the head and thorax more generally of a less distinct blue. The thorax is very 

 finely and not very closely punctured. The elytra at the base are as wide as the base 

 of the thorax, scarcely widened at the middle, narrowed posteriorly for some distance, 

 and then very obliquely narrowed at the apex; moderately strongly punctured at the 

 base, smoother at the apex ; each elytron has an obliquely transverse white spot near the 

 apex. The terminal segment of the abdomen of the male has three triangular teeth 

 on each side, separated by a wide space or excision, the base of which is nearly 

 rectilinear ; the second tooth is a little longer than the first, and the third or outer one 

 is smaller and at a lower level (fig. 21).
