Anthonomus lapsus sp. nov. 



PI. XIII., Fig. 5. 



In a third species of Anthonomus the elytron is a little larger than in 

 A. disjunctus LeC, with which it can best be compared, though the rela- 

 tion is not very close. There is the same flatness of the interspaces, but 

 the striae are broader with more sloping sides, while the puncta are a little 

 larger and more distinctly impressed. The elytron is piceoiis, 3™ long, 

 and 1 •2'™ broad. 



6ne specimen : No. 16861, Reservoir Park, Toronto. 

 A. disjunctus is found in Illinois and Georgia. 



Orchestes avus sp. nov. 

 PI. XIII., Fig. 4. 



A complete right elytron of great relative breadth seems to belong to 

 Orchestes. The two outer and two inner strise unite apioally and another 

 pair of loops within them is formed by the third and sixth, and by the 

 fourth and fifth strise, while besides these the seventh and eighth striae 

 are united apically at about the middle of the distal third of the elytron. 

 The strise are rather coarse and well pronounced, but the puncta are rela- 

 tively obscure. The whole is dead black. It seems to be rather closely 

 related to 0. niger Horn, but in this species the fourth stria from the 

 suture unites with the third, and the whole apical arrangement of the 

 strise becomes thereby different. The fossil is a trifle larger but of the 

 same form, the strise less deeply impressed and the puncta more obscure. 

 The length is l-S™, and the breadth 0-9""°- 



One specimen : No. 16867, Logan's brickyard, Toronto. 



0. niger is known to occur in Nova Scotia, Canada, Illinois and Cali- 

 fornia. 



Centrinus disjunctus sp. nov. 

 PI. XIII., Fig. 3. 



The basal half or less of an elytron shows ten nearly straight delicate 

 strise, with delicate punctuation and flat punctate interspaces, all of 

 which closely resembles the appearance of C calvus LeC. It is of about 

 the same size apparently, and differs in being piceous and not castaneous.
