124 THE ENTOMOLOGIST. 



pale yellow, and was thiclily covered with white powder 

 along the posterior margin ; as usual, the eyes were inserted 

 in round black spots (see fig. 2). The claws of the anterior 

 legs were brown. 



After the larvge had moulted for the last time the white 

 powder had entirely disappeared. The head now assumed a 

 shining, ochre-brown tint, with black spots, in which were 

 the eyes (figs. 3, 4) ; the body was of a pale, feuille-morte 

 colour, and wrinkled, the skin being in folds as before. They 

 descended into the ground for the purpose of passing into the 

 pupa state ; but as on the occasion of making these observa- 

 tions I only had one or two examples at a time, and I am 

 convinced that any disturbance of the mould prevents the 

 completion of the metamorphosis, I let them remain quietly. 

 Thanks to which, it may be, the iraagos appeared ; but in 

 consequence of which I missed the opportunity of observing 

 the pupa. 



The perfect insects were produced at the beginning of 

 October: I find two dates mentioned in my notes, namely the 

 3rd and the 14th of that month. Having regard to the length 

 of the body, and more especially to the neuration of the 

 wings, they certainly belong to the genus Eraphytus ; the 

 structure of the antennae, however, approaches more nearly 

 to that of Nematus, while the habit of the larva closely agrees 

 with that of many species of Selandria. The head is quadrate, 

 with rounded angles (looked at from above), black, and 

 thickly clothed with very short hairs; the sides of the head, 

 behind the eyes, are very projecting, and the vertex has a 

 number of elevated points. The labrum is very hairy ; the 

 mandibles are short and broad ; the palpi are rather long, the 

 middle joints being of a whitish tint. I'he thorax is clothed 

 with a short pubescence ; the tegulse are brown, and the 

 cenchri clear white. The first abdominal segment is black, 

 and deeply notched on the posterior margin, so that, as is the 

 case with the males of Cimbex, a considerable triangular 

 space remains open, within which a white membrane is seen. 

 The rest of the abdomen is shining and orange-yellow, both 

 on the dorsal and ventral surfaces. The valves of the 

 ovipositor are dark brown, nearly black. The antennae are 

 black, and are longer than is generally the case in the genus 

 Emphytus. Wings transparent, iridescent, a little darker at
