24-6 [April, 



On tearing open the coarse reticulation of white silk which held 

 the leaves together, and formed a lining to the oblong puparium an 

 inch and a quarter long, I found the pupa itself to be of the length 

 of 8| lines and very similar in form to that of its congener ActcBon* 

 having the end of the trunk lying free from the abdomen, held in 

 position, head upward, by an oblique cincture behind the thorax, and 

 the anal tip secured by a fan-like spread of fine hooks at the extremity 

 fixed in the silk lining, but the head had the frontal tapering beak 

 shorter and more bluntly pointed, the colour then was the same light 

 green as that of the larva, of which the paler lines could still be 

 faintly traced.

A NEW BRITISH SPECIES OP CRABSO—C. KOLLABI, DAHLB. 

 BY EDWAED SAUNDERS, F.L.S. 



Mr. Billups has been fortunate enough to capture two males of this 

 interesting species near Headley, and I find a male in my own collection, 

 which was originally in Shuckard's, mixed with C. interruptus, De 

 Gr.,^=Lindenius, Shuck., but without note of locality. It very closely 

 resembles interruptus, and the other yellow-banded species, but may 

 be easily distinguished by the sculpture of the mesothorax, which is 

 strigose behind and at the sides, but punctate in front across the 

 middle, whereas, in interriipfns, it is transversely strigose in front ; 

 from the other yellow-banded species the male may be known by its 

 simple antenuie and tarsi and the sculpture of the thorax. The $ 

 has not yet been taken in this country, so far as I know, but Dahlbom 

 says that it agrees with the (^ in sculpture ; both sexes are rather 

 smaller than interrupt us: it may be briefly characterized thus :

Head and thorax black, mandibles piceous at the apex and bifid, the teeth 

 rather shorter than in interruptus. Antennae simple, basal joint yellow, with a black 

 line above. Prothorax with two yellow spots. Mesothorax punctured, with strise 

 diverging from the base, which leave a space on the anterior margin, which is simply 

 punctured, and in which are two short carinae originating from the anterior margin. 

 Wings darker than in most species. Abdomen with lateral spot on the 2nd to 4'h 

 segments, and an entire band on the 5th and 6th, apex of the 5th and 6th and the 

 entire 7th dark. 7th segment simple, not deeply impressed longitudinally as in 

 interruptus, beneath brown, shining ; legs with the femora spotted with black 

 behind, the posterior pair entirely black ; tibiaj more or less spinose. 



Length, 10 mill.
