THE CALLIMENUS. 323 



are without wings, the male possesses those organs ; but here is 

 one of the exceptional examples to which allusion has already 

 been made, where neither sex possesses' wings. In order to show 

 more fully that this is the case, the illustration has been drawn 

 from a male insect. The female is very much like the male, but 

 is at once known by the short, broad, sharp-pointed, sabre-shaped 

 ovipositor, the blades of which have a strong tendency to sepa- 

 rate after the death of the insect. 



The insect is a curious, but not a pretty one. The squared 

 thorax is green, bright during life, but becoming dull yellowish 

 green after death. The thick, rounded abdomen is almost 

 entirely dull red, upon winch are a number of black patches, 

 placed as seen in the illustration. These black patches are 

 slightly raised above the rest of the surface, and are thus 

 much more prominent. Towards the end of the abdomen there 

 are a number of green patches, so that the ungainly form is 

 in some way compensated by the variety of colour. 



One species, Callimenus dasypus, of Hungary, is entirely black, 

 shining, and granulated like very rough sand-paper. It has a 

 number of large tubercles along the back. There are some most 

 extraordinary insects allied to the Callimenes, of which Lesina 

 lutescens is perhaps the most singular. It is a little, flat, yellow 

 creature, with its head developed into a sharp projecting spike, 

 and its long thorax furnished with three distinct sets of jagged 

 spikes, laid flat on the back, each set looking very much like 

 some of the ancient battle-axes. 



Another is Vates laMfolium, which bears, as its name imports, 

 a singular resemblance to a leaf. It has no spikes like the pre- 

 ceding insect, but its body is flat, and shaped much like that 

 of the Phyllonemia, which has already been described, except 

 that it is, if possible, rather flatter, while the legs are furnished 

 with flattened, ragged-edged appendages, that look exactly like 

 scraps of torn and jagged leaves. Instead of the bold spikes of 

 Lesina, it has a number of fine, needle-shaped prickles on the 

 thorax, which look exactly like the hairy edges of a leaf-stem, 

 so that when the creature is alive and green, the resemblance to 

 a leaf is wonderfully exact. 



On pp. 324 and 325 are depicted two figures of the same 

 insect, showing the difference of appearance which sometimes
