ORDER COLEOPTERA. 331 



ring red, in the form of a plate, having two sorts of cylin- 

 drical horns, as it were annulated or articulated, and arched 

 within. It has six small feet. 



Another species, but smaller, altogether black, with the ex- 

 ception of the elytra, which are red, and the end of the an- 

 tennae, which is reddish (Lycus minuhis, Fab. Panz, Faun. 

 Insect. Germ. XLI. 2), is also found in France, but in fir- 

 woods of the mountains.* 



Omalisus, Geoff. Oliv. Fab. 



Have no very perceptible muzzle. The articulations of 

 their antennae are almost cylindrical, a little attenuated at 

 their base, and the second and third are much shorter than 

 the following. The penultimate of the tarsi alone is in the 

 form of a reversed heart. The others are elongated and cylin- 

 drical. The elytra are of a tolerably solid consistence. 



O. Suturalis, Fab. Oliv. Col. II. 24, 1,2. A little more 

 than two lines in length, black, with the cases, their anterior 

 portion or suture excepted, of a blood-red. In the woods of 

 the environs of Paris, and particularly of the forest of St. 

 Germain, on oak-trees in spring. (See the article Omalise of 

 the Encyc. Method.) 



The other lampyrides of our first division are distinguished 

 from the preceding, not only by none of them having any 

 muzzle, and that their head, almost entirely occupied by the 

 eyes in the males, is concealed totally, or for the greater part, 

 under a semi -circular or square corslet, but still more by a 

 very remarkable character, either common to the two sexes, 

 or peculiar to the females, that of being phosphorescent. 

 From this comes the names of glow-worms, luminous-Jlles, 

 Jire-Jlies, given to these insects. 



The body of these insects is very soft, especially the ab-
