longer, and the antennae are serrated. The elytra are most commonly 
dilated, either laterally, or at their posterior extremity, the two 
sexes differing greatly in this respect, particularly of certain species 
peculiar to Africa *. 
Other species of the same author, but with very short snouts, and 
whose compressed antennae, sometimes simple, and at others serrated 
or pectinated, have their third joint longer than the preceding one, 
and in which the intermediate joints of the tarsi have the form of a 
reversed heart, compose a second subgenus, the 
Dictyoptera, Lat. 
In some of the woods in the vicinity of Paris, on the flowers of 
the Yarrow, and of other plants, we frequently observe the 
Lycus sanguineus ; Lampyris sangumea, L. ; Panz., Faun, 
Insect. Germ. XLI, 9. About three lines in length; black; 
sides of the thorax and the eltyra blood-red ; elytra silky and 
slightly striated. The larva lives under the bark of the Oak. 
It is linear, flattened, and black, the last ring red, resembling a 
plate with two kinds of horns, cylindrical, and, as it were, 
annulated or articulated, and arcuated inwards. It has six small 
feet. 
Lycus minuhcs, Fah. ; Panz., Faun. Insect. Germ., XLI, 2. 
Smaller; all black, the extremity of the elytra excepted, Avhich 
is red, and the end of the antennae, which is reddish. Also 
found in France, but in forests of the Mountain Fir f. 
Omalisus, Geoff, Oliv. Fab. 
No apparent snout; joints of the antennae almost cylindrical, 
slightly reduced at base, and the second and third much shorter than 
the following ones ; penultimate joint of the tarsi alone in the form 
of a reversed heart ; the others elongated and cylindrical ; elytra 
tolerably solid and firm. 
O. suturalis. Fab, ; Oliv,, Col. II, 24, 1, 2. Rather more than 
two lines in length, black, elytra blood-red, the suture excepted. 
Found in the woods in the vicinity of Paris, and in the forest of 
Saint Germain particularly, on the Oaks, in spring J. 
The other Lampyrides of our first division are distinguished from 
the preceding ones, not only by the want of a snout, by their head, 
which, in the males almost entirely occupied by the eyes, is entirely 
or for the greater part concealed under a semicircular or square 
thorax, but also by a very remarkable character, either common to 
both sexes, or peculiar to the females, that of being phosphorescent, 
whence the names of glow-worms, fire-flies, &c., given to these 
Insects. 
Their body is extremely soft, the abdomen particularly, which has
