 — This is commonly about an inch and half long, of which the head takes up a 

 third part, which is nearly as broad as long ; the sides are grey or frosty ; the 

 middle black : what in this part are most remarkable, are, two very black oval 

 spots, in texture, colour, and softness much resembling the finest black velvet, 

 being encompassed with a whitish circle. These orbicular spots at first view 

 seem to be their eyes, though they are ten times less, and placed at the setting 

 on of the horns, which are about half an inch long, composed of 8 serrae, or 

 teeth, notched on the under side only. The vaginas, or wing-sheaths, are 

 long, black, sulcated, and plentifully sprinkled with white specks, the under 

 part and belly is frosted on the sides, and in the middle of a shining black. The 

 structure of this insect is the same with a peculiar species I have seen in England, 

 and called snap-beetles, from their elastic or springing faculty, by which they will 

 easily force themselves out of your fingers ; I have also frequently observed, 

 that if you lay them on their backs, not being able to turn on their bellies, they 

 will spring or raise themselves to a wonderful height, and that for several times, 

 until they fall on their legs.

 coides Marianus, vaginis ex nigro aurantioque mixtis. 16. Cicindela Mariana, 

 the fire-fly, vaginis teneris fuscis marginibus fulvis. 17. Cantharis Anglica 

 viridis, maculis aureis insignita. 18. Cantharis Mariana viridis, lituris margi- 

 nalibus aureis insigniter notata. The spots in this are larger and finer marked 

 than the last. ig. Cantharis Mariana fusca, meandris marginalibus pallidis in- 

 curvatis. 20. Capricornulus nigrescens Marianus, undis et circulis flavescenti- 

 bus striatus. 



Sect. IV. Plants. — Muscus Filicinus Marianus repens pinnis brevioribus. 

 This diflx?rs from our common fern moss in having shorter wings set opposite 

 from the middle rib, which creeps along the ground, and is not branched. 2. A. 

 Branched coralline moss. This grows with us very plentifully on most heaths. 

 3. Trichomanes major Marianus longifolius, an trichomaues major foliis longis
