from it (and its allies), and from any other known genus of recent 

 OalopterygincB, in the position of the nodus, in which it shows a distinct 

 analogy with the Agrionince. The form of the pterostigma is as in 

 Amphipteri/x and Devadatta {Tetraneura, Selys). The number of 

 ante-nodals is practically as in the Agrionince, because the last two or 

 three are finer than the others, and do not extend below the subcosta. 



Thaumatoneura inopinata, n. sp. 



Adult t?. Body deep black. A rounded orange coloured spot on the frontal 

 orbits. Pronotum narrowly edged with orange at the sides. Thorax (damaged 

 above) with four equidistant slender yellow lines on each side ; one humeral, two 

 lateral in the sutures, and one margining and continued round tlie pectoral area. 

 Legs black (only anterior present), femora dingy yellowish, tibiee with long black 

 spines. Abdomen bronzy, a fine yellowish, dorsal, longitudinal crest ; the segments 

 (after the second) with fine and close transverse corrugations. 



Wings hyaline, with a very broad, dark brownish-black, opaque band (in which 

 there are irregular pale points where the pigment has not developed) in all the 

 wings, occupying the space from the nodus to beyond the middle (or more than one- 

 third of the entire length in the anterior, and one-half in the posterior) ; internally 

 the edge of this band is ill-defined, shading off gradually, and causing the otherwise 

 hyaline basal portion of the wings to be somewhat smoky ; externally it is well- 

 defined, but irregular in the anterior, where it is excised below the costa, then 

 roundly dilated, and afterwards somewhat concave ; in the posterior the external 

 edge is nearly regularly concave, with a slight projection before the middle ; beyond 

 this band the wings are hyaline. Pterostigma (length, 5t mm.) and reticulation 

 black. About 70 post-nodals in the anterior-wings. 



Length of abdomen (26 mm. to end of 4th segment*). Length of posterior 

 wing, 48 mm. Greatest breadth of anterior wing, 13 mm., of posterior, 14 mm.

ON THE OCCURRENCE OF BLENNOCAMPA ATERRIMA, Klug, 



AT KEW. 



BY DR. A. GIJNTHER, F.R.S., P.L.S., &c. 



I first noticed this saw-fly in my garden at Kew in 1892t on a 

 clump of Solomon's Seal, which I had obtained from a neighbour. No 

 specimen of the insect had been noticed, then or before, in the original 

 location of the plant, and there were only a few individuals in the 



* From analogy the entire abdomen should be of exceptional length. There is nothing to 

 indicate that the I'ortion that remains has at any time been detached. This is mentioned 

 because there were some extraordinary cases of " reparations " in the collection ; for instance, 

 an example of Sieboldias Albardce, Selys, with the abdomen of JEachna cyanea ; and the curious 

 Stilbopteryx costaCis ( Myrmeleonidcv) with the head of an JEschna ! !
