Curculioides ansticii, Buckland. Plate II, fig. 7; Text-figures 12, 13. 



1837. Curculioides ansticii, W. Buckland, Bridge water Treatise (ed. 2), vol. ii, p. 76, pi. 46", fig. 1. 



The exposed surface of both dorsal and ventral sides is closely covered with 

 small punctures marking the hollows of granules. A specimen in Mr. Bgginton's 

 Collection (PL II, fig. 7), showing the dorsal surface from the ventral side and the 

 ventral surface from the dorsal side on the two halves of a split nodule, has the 

 carapace flattish and only a little vaulted, and apparently about as wide as long, 

 though its lateral margins are not clearly defined. The posterior end of the 

 abdomen is markedly narrowed. Portions of the legs are well shown, especially on 

 the right side. The first and third are preserved as far as the end of the patella,

of the second and fourth as far as the end of the femur. The first lea' is the 

 thinnest and the second the longest of the series, the femur of the second being 

 about as long as the femur -f- patella of the third. Approximate measurements 

 in mm. : Total length about 11, length (without cucullus) and width of carapace 4, 

 length of abdomen 6"5, length of trochanter and femur of first leg 4, of second 6, 

 of third 5, of fourth 6*5, of the femora alone in the order named 3, 5, 3, 3*5. 



Another specimen (No. 17) in Mr. Egginton's Collection shows no structural 

 features not exhibited in the first and is much less perfectly preserved. The 

 abdomen appears to be more evenly oval and less narrowed posteriorly. The 

 entire animal, in fact, seems to resemble G. scaber of Scudder in shape. Approxi- 

 mate measurements in mm. : Total length 12, length of carapace 4, width of cara- 

 pace 4, length of abdomen 8, width of abdomen 5. 



In Mr. Madeley \s Collection there is a fairly well-preserved example showing 

 the cucullus apparently entire. It has convex lateral margins and rounded angles ;
