SECT. V. De Hydr.rocanthar.is, or Water-Beetles. 

 The Horns of moit are jointed, flender and needle-pointed, 

 and fome pectinated ; yet, fmce they are all found in the 

 Water, I would not feparate them. 



1. Hydrocantharus maximus la;vis antennis peftinatis Gaz. 74. 

 11. Hyd. major Anglicus Moffet. Scarabaus 2. aq. Aldrovand. 

 Infect. 449. defer, fig. 2, 3. p. 500. Id. ed. Francof. tab. 8. 

 fig. 2, 3. p. 178. It is about two inches long, and near one 

 broad ; the Iheaths extended above two and a half. It is black, 

 fmocth and Ihining above : the light furrows on the (heaths are 

 widell and moft apparent towards the tail : it has two pair of 

 feelers, thofe next the mouth much the fhorter : its horns end 

 pectinated, or comb-like. Along the middle of its belly runs a 

 xib, terminating in a Ihining fharp thorn : the tips of the two 

 tinder legs are hairy, with a long flender fpine on the infides of 

 the next joint : the ends of its fore feet are forked. From Wif- 

 bich, and in ponds beyond Iflington. Moffet fays, thefe fly in 

 the night, but in the day are rarely feen out of the water. . 



2. Hydrocantharus max. lsevis, pollicibus lanceatis Gaz. 74. 1 2. 

 Differs from the foregoing, only in having a lancet, or a farrier's 

 fleam-like protuberance, next the extremities of its fore feet only. 

 I fuppofe thefe male and female. 



3. Hydrocantharus medius ater lucens Gaz. 70. 4. Wholly 

 black, fmooth, and very Ihining ; 1 \ inch long, \ broad ; its 

 feelers of three joints, the tips fhorteft ; its horns pectinated. 

 N. B. Thefe three laft are Ddta-hz.ck.zd, i. e. with a triangular 

 fliell in the midft of its back, between the Iheaths. 



4. Hydrocantharus minor latus nigrefcens. Is much flatter than 

 the laft, and fmaller, viz. f long, and \ inch broad ; fmooth and 

 Ihining, but not fo black. 



5. Hydrocantharus minor latus rubefcens. Dandridge. Same 

 Iize and fhape with the laft, but not fo ihining ; iheaths reddifh, 

 with head and moulders black. Found in a pit in Hornfey Wood.

 velociter circumnatans Gaz. 13. 9. Scarabaus aq. fubrotundus 

 £ cserulco viridi colore fplendente undique tinftis Ray Hift. Infect, 

 p. 87. io. This muft be our common Water-Flea, though he be 

 fomewhat miitaken in the colour; fmce this is the only Beetle 

 that fo fwims on the furfacc : § an inch long, | broad ; very 

 fmooth and ihining, of a black fteely hue. Common in all 

 ditches- and ponds. 



7. Hydrocantharus major laevis, marginibus flavis Gaz. 72. 8. 

 5. Lifter, tab* muds. Some of thefe are above 1 § inch long, and 

 about half as broad: they are fmooth and blackiih, but edged 

 with a dull yellow : thefe have ftriated fpangles on their fore 

 feet (which are accurately expreiTed in Mr. Petiver's Tables :) 

 their horns are very flender, long and jointed, accompanied with 

 a pair of fhort feelers. 



8. Hydrocantharus major ftriatus, marginibus flavis Gaz. 72. 

 8. 1. Very like the laft in colour and magnitude ; but its iheaths 

 deeply furrowed, except the tips, Avhich are fmooth. This is not 

 fpangle-footed. 



9 Hydrocantharus major ftriatus, ventre nigricante. Dandridge. 

 This differs from the laft, in being a degree lefs, and without 

 yellow lifts crofs. the shoulders ; but particularly, in having a 

 black ihining belly ; whereas the others aremoftly buff. This is 

 the only one Mr, Dandridge has as yet feen, who caught it in 

 the gravelly water-pits beyond Iflington, in a field. Thefe three 

 laft have fmall delts or triangles. 



10. Hydrocantharus medius laryisGaz. 70. 3. Flydrocanth. 4 Lift, 

 tab. mutis. Refembles No. 7. but much lefs, viz. | long, iinch 

 broad ; the fheaths fmooth, but not fo black as the laft : if looked 

 through, they are tranfparent, and finely mottled and fpecked with 

 black; its fhoulders and edges yellowiih, as No. 7. and 8. This is 

 fpangle-footed, which I obierve is more particular to the fmooth 

 cnes, as No. 2. and 7. and belongs but to one of the fexes. 



11. Hydrocantharus medius ftriatus Gaz. 70.2. Scarabaus aq. 

 minor Aldr. Infecl. 455. fig. 6. edit. Francof. 178. fig. Of the 

 lhape and fize with the laft ; but its Iheaths broad, and deeply 

 furrowed, with not above five in each ; whereas No. 8. has as 

 many more, and thick fet. N. B. The membranaceous wings of 

 #11 tlie foregoing are not above a quarter part longer than their 

 flieaths or cafes. 



12. Hydrocantharus medius, laevis oblongus. This chiefly dif- 

 fers from No. 10. in being narrower, longer, and not fpangle- 

 footed.

 half the iize of the laft, with a black fpot in the midft of its yel- 

 low Ihoulder.

 ■ccnte. Steel. Thefe are about the iize of Brackenclocks, but 

 fmooth, and of a blackiih or dirty hue, mixed with fomewhat 

 paler lights ; its jointed horns hair-like, and pointed. At Den- 

 ham, Bucks. 



15. Hydrocantharus parvus nigrefcens. Like the laft, but four 

 times leis. Moft of thefe are found in the ponds, ditches, and 

 {landing waters, about town. Mr. Willoughby obferves all water- 

 beetles to be very nimble ; and when they happen to lie on their 

 backs, they jump themfelves on their legs by leaping. 



SECT. VI. Scarae/ei Elastici, or Snap-Beetles; be- 

 caufe, if you hold their bodies between your fingers, they 

 will with their head and fhoulders fnap with that force, that 

 you can fcarce hold them : They h^ve alfo fuch a fpringing

faculty, that, if you lay them on their backs, they will jump 

 up divers times, till at laft they fall on their feet. The na-« 

 ture of thefe is alfo very well defcribed by the accurate Mr. 

 Ray, in his Hift. Infect, lately publifhed, p. 78. 13. and by 

 the learned Dr. Lifter, in the fame book, p. 387. cap. 3.

 three quarters of an inch long, and anfwerably broad, with black 

 ftreaked Iheaths.

 curious and varioufly marbled, according to thepofition of light. 



N. B. All, or moft of thefe fnaps have been obferved in Cain* 

 Wood, at divers feafons. 



SECT. VII. Curculiones, or Pipers; from their long 

 fnout, out of which come their horns : thefe are fmooth and 

 flender at fetting on, bending in the middle, and thence 

 jointed to the ends, which generally terminate pectinatedj, 

 as is obvious in one of the largeft of this kind, Gaz. 3;. 5.

 be winglefs. 



29. Curculio minor rugofus niger. Small, Black, Rugged Pi- 

 per. This is more deeply furrowed and pounced than the laft,
