while ill normal V. io only the large spots in the outer angle, two 

 shown also in A. levana,fig. 4, are plainly marked in the under 

 side. The " tortoiseshell " Vanessids develop the whole chain 

 of spots also — sometimes both in the upper and under side — but 

 the spots are only rudimentary, their real centres being visible 

 mostly only in Grapta-si:>e(iies. In the Pyrameids tn^o of these 

 spots — in each iving part one — are usually far advanced by de- 

 velopment. The Araschnids develop these markings much as 

 they are found in the atalanta-form Pyrameids. All the 

 Araschnids mentioned hitherto were fasciated at least in their 

 under sides, but fig. 8 shows the normal facies of A. davidis 

 (male), in which the central fascia is masked, and it may be of 

 interest to note the markings by which the process of masking 

 up is accomplished. 



Fig. 6 (drawn three-quarter size) represents an aberration of 

 P. atalanta (reared on September 22Qd, 1908), which shows one 

 of the most characteristic Araschnid markings — a light line bor- 

 dering the median ocelli. The Araschnid fascia is also traceable, 

 and its upper part can he seen to have ivandered towards the base of 

 the wing ; P. indica and the cardui-form. species (also species of 

 Hypanartia) show transitory stages of this movement. If the 

 under side hind wings of V. io and of the ''tortoiseshell" 

 Vanessids are compared, it will be found that also in these 

 the Araschnid fascia is plainly traceable, and that it occupies 

 exactly the same position in every wing as shoicn in the aberration of 

 P. atalanta, Jig. 6. In normal P. atalanta the fascia is found in 

 the same position, but it is not so plainly marked by lighter 

 colours as in fig. 6.

A NEW SPECIES OF TRACHYPUS FEOM 

 ERYTHRINA, RED SEA. 



By p. Cameron. 



Trachypus curvimacnlatas, sp. n. 



Black, shining, a transverse broad line on the top of the face, the 

 sides obliquely narrowed below, the incision forming a curve, the 

 central lower part rounded ; the part below the antennae, except for 

 a longish triangular black spot below each antenna?., the spot continued 

 below along the suture and ending in a rounded spot which is dilated 

 outwardly ; laterally the mark is continued to the middle of the eyes, 

 the upper half being obliquely narrowed, and the mandibles broadly 

 at the base, pale yellow. The following markings are bright orange 

 yellow : a large tx'ansverse spot, broadly rounded above, the apex 

 transverse in the middle, the sides (this part wider than the central) 

 roundly obliquelj' narrowed, a curved line behind the ocelli reaching
