both sexes, and 7-jointed, the three terminal joints rather thicker than the 

 preceding, and not soldered together ; abdomen ovate-depressed, and gra- 

 dually becoming acute to the tip ; wings of the male not more than half 

 the size of those of the female. 



Spec. 1. Hem. fulvicollis Westw. Viridis; collari et mesothorace fulvis

 basin aureo-viridi, pedibus flavis, femoribus intermediis supra linea nigra, 

 alis <$ apice late fuscis, $ hyalinis, nubila semilunari centrali subfuscescenti. 



Green ; front of the thorax fulvous ; abdomen pitchy tinged with green, 

 golden green at the base, less yellow, the central tibiae having a black line ; 

 wings of the male terminated by a large brown patch ; those of the female

Spec. 2. Hem. Waterhoiisw Westw. £ obscure aeneo-cupreus ; abdo-

Dark coppery aeneous, the abdomen having a darker coppery tinge ; 

 anterior legs, intermediate tibiae and tarsi, and posterior tarsi, red ; inter- 

 mediate femora, and posterior femora and tibiae, pitchy black ; wings £ 

 with the terminal half dark brown, having two slender pale fasciae run- 

 ning across the wings, near and parallel to the posterior margin.

I have named this conspicuous species after the indefati- 

 gable and zealous young entomologist above named, who cap- 

 tured it at Dorking. The antennas are broken off at the third 

 joint ; but from the formation of the basal joints, and the 

 shortness of the wings, I have no hesitation in uniting it 

 in the same group with the preceding species, although differ- 

 ing in one or two minor particulars.

 This singular worm is to be found abundantly in Berwick 

 Bay. It lurks under stones, in a somewhat muddy soil, in 

 which it forms burrows similar to those of the earthworm, 

 and into which it retires slowly when disturbed. As yet it 

 seems not to have been noticed on any other part of the 

 British coast ; but, when this department of natural history is 

 more studied, it will probably be discovered to be common,
