SYNOPSES OF CERAMBYCID^. 

 By Chas. W. Leng, B. S. 



(Continued from p. 24, vol. III.) 



These two species have been much confused. Both vary in color 

 from entirely black to nearly entirely rufous, the tip of the elytra remaining 

 black in all I have seen. There is usually in pint an oblique line of silvery 

 pubescence but it is (rarely) scarcely visible and though usually absent in 

 picipes it is sometimes indicated. The thorax of picipes scarcely shows a 

 sign of the lateral depressions forward which are conspicuous in pint, 

 making the subangulate form more pronounced and finally the difference 

 in the eyes is conclusive. Dr. Leconte mentions that thesubbasal elevation 

 of the elytra is more prominent in pint but poorly developed specimens 

 occur in both species in which the difference is not appreciable. 



Eu. spinicornis Chev. , (elegans Lap), has occured in Mexico near 

 the boundary and is easily known by the long spine of the 3d joint of 

 antennae. 



Eu. Reichei Lee. S. M. C, No. 264, 1873, p. 202. 



Length 4 to 5 mm. = .16 to .20 ins. Hab. Texas, Illinois. 

 Easily distinguished by the direction of the ivory band. The pro- 

 thorax also is punctured not longitudinally striate as in the other species. 



Eu. parallelus Lee. 1. c. 



Length 5 mm. = .20 ins. Hab. Lower California. 

 The anterior ivory band extends from the suture to the outer third, 



the hinder one is entire. This species I have not seen.

Since writing the note on N. approximates (Ent. Am., vol. Ill, p. 7) 

 I have seen several specimens of that species in Mr. Henry Ulke's collec- 

 tion — all identical with Dr. Horn's specimens. Chas. W. Leng. 



Mr. Leng (Ent. Am., vol. Ill, p. 6) savs of Neoclytus scutellaris : 

 "the [middle] band of thorax is always distinct." I have seen specimens 

 in' which it must have been totally lost by abrasion if it ever existed. The 

 form of the scutellum is characteristic and readily separates it from X. 

 luscus, from which in this case it would otherwise be undistinguishable. 

 In the latter it is transverse oval ; in the former elongate triangular with 

 the apex rounded — characters L have not seen mentioned in the literature 

 of the species. N scutellaris is comparatively rare in the North, and a 

 form of A' luscus with a red interrupted fascia occupying the same posi- 

 tion is put for it in exchange. This fascia, however, is one of integumental 

 coloration, and not a line of pubescence, as in X. scutellaris.*

 * I>r. Hamilton i> quite right, though the character is not very apparent without 

 careful comparison ol both species. Ass't Ed.
