Figures, comp. p. 374 : — Fig. 33, the tambourine of the left elytron, magnified : u, vena ulnaris, forming the 

 limit of the dorsal field ; a, v. analis ; x, v. prima axillaris ; z, its continuation or v. post-axillaris 

 prima; n, its anastomosis with the anal vein (u); A, its inner branch or v. stridans ; x ', x", the two 

 parts of the secunda v. axillaris, confused in o, then separated again and emitting the connecting branch c ; 

 u, nodus analis vel musicus ; b, point of division of the second axillary vein x', x" ; z", normal continuation 

 of the second axillary vein, or v. post-axillaris secunda ; z, the outer branch of the second axillary 

 vein, reinforcing the support of the stridulating vein, A; t, connecting branch for the reinforcement of 

 the same ; s, speculum centrale, or central (inner) drum ; e, speculum externum or external drum. — 

 Fig. 34, the tambourine of the right elytron. The same letters designate the corresponding nervures. 

 The two branches of the second axillary vein (x, x"), after their conjunction in o, do not turn round the 

 end of the stridulating vein A, to form the inner transverse vein z', nor the external branch z", as in the 

 left tambourine, but are broken away from their branches, and thrust inward to border the inner 

 margin of the elytron, so as to form the trill-organ {ilex, i) upon which the v. stridulans of the left 

 tambourine rubs. The end of the inner branch z" thus fuses with the stridulating vein A and forms its 

 continuation.
