The work concludes with an explanatory Index, I believe the first 

 that has been attempted : of this a specimen is given below. 



Convoluta, (lacinia) is rolled up below the 

 head like the mainspring of a watch, 

 figured, 162 



Corcula, the reservoirs in the dorsal chan- 

 nel through which the blood of insects 

 flows, 187 



Coriaceae, (proalee) when composed of a 

 tough substance which bends without 

 breaking, but never folds, 166 



Coriaria, (lacinia) long, leathery and flex- 

 ible, as in bees, 162; figured, 161, u4 



Laetus, implies that a colour is very bright, 

 175 



Lasvigatus, when the surface is perfectly 

 smooth, without impressions or eleva- 

 tions, 176 



Lacinia, the blade of the maxillae, being 

 the fourth or apical portion, 162; fi- 

 gured 161, M 4 



Lamellatae, ( antennae ) when the apical 

 portion only is flabellate, 1 56 ; figured 

 156,9 



Pectiniformes, (antennae) when the joints 

 are furnished on one side with slender 

 processes resembling the teeth of a 

 comb, 156; figured 156, 7 



Pedunculated insects, are so called when 



they have the sixth segment or podeon 

 slender and thread-like, as the wasp, 

 &c., 145 



Perforatae, (antennas) when a portion of 

 each joint is dilated and flattened, and 

 the remaining portion being cylindrical, 

 appears like a thread on which the dila- 

 ted parts are strung, 158 



Pulvilli, the soft cushions on the under 

 surface of the joints of the tarsus in 

 some insects, 170 



Pulvinulus, a soft ball at the end of the 

 tarsi, 171 



Puniceus, red inclining to orange, 174 



Puncto-striatus, when the longitudinal 

 impressed lines are punctured, 176 



Punctus, when the surface has the appear- 

 ance of having been thickly punctured 

 by the point of a pin, the pin not pass- 

 ing through, but simply making an im- 

 pression, 176 



Pupa is the quiescent state which some 

 insects assume when full fed, prior to 

 their undergoing the final change, 2 



Pustulosus, when covered with pustules, 

 resembling those occasioned by the 

 small pox, 176
