INTRODUCTION. 



Eyes completely divided ; antennae 



abnormal, very short 



Posterior coxae very widely separated ; 

 metasternum emarginate before them, 

 very large, almost as long as the 

 abdomen ; antennae moniliform ; legs 

 ambulatorial 



Gyrinidae, p. 65. 



Rhysodidae, p. 68. 



II. Abdomen with four visible ventral segments 



(the basal segments being connate without 

 apparent suture) ; antennae with 2-11 joints *, 

 usually more or less abnormal ; metasternum 

 with an antecoxal suture extending almost 

 across its breadth, slightly produced between 

 the posterior coxae , Paussidae, p. 67. 



III. Abdomen with five free ventral segments ; 

 antennae 11-jointed ; metasternum with a 

 deep antecoxal suture, extending almost across 

 its breadth, scarcely produced between the 



posterior coxae Cupedidae, p. 68, 



Family 1. CICINDELID^. 



CI y pe us extending laterally in front of the insertion of the 

 anteniw ; head large; eyes large and prominent; antennae eleven- 

 jointed, inserted on the forehead above the base of the mandibles, with 

 the joints, except the four based ones, finely pubescent ; maxillce with 

 the. outer lobe two jointed (sometimes rudimentary and setiform 

 (Therates)), the inner lobe (or lacinia) nearly always terminated by 

 an articulated hook {except in Ctenostomld^e) ; abdomen ivith the 

 three anterior segments connate, with six ventral segments visible in 

 the female, and seven, as a rule, in the male; legs slender,, formed 

 for swift running ; posterior coxce dilated internally, not reaching 

 the sides of the body ; venation of ivings irregular, the areola oblong a 

 nearly always wanting. 



As the Cicindelijle are described in the present volume there 

 is no need to say much about them. From the ferocity of their 

 nature (as well, perhaps, as from their colouring), they are often 

 called " Tiger Beetles,'' a name which they well deserve. Their 

 larvas, moreover, are more ferocious than the perfect insects ; but 

 comparatively few have been discovered, and nothing is known of 

 the life-history of some important genera (e. g. Tricondyla and 

 Therates) ; quite recently a larva of the genus Colly vis has been 

 described by Mr. Shelford, a full account of which will be found 

 in the following pages. 



* Ganglbauer (Die Kafer Mitteleuropa. i, p. 3) says 2-6 or 10 joints, but the 

 comparatively recently described genus Protopanssus has the antennae normal 

 and il-jointed.
