BULLETIN OF THE BROOKLYN ENT. SOC. 



The head is always distinct, usually corneous with one to six 

 eyes (ocelli) at its sides behind the antennae. 



The antennae are seldom wanting and consist of not more 

 than four joints sometimes augmented by laterally inserted joints, 

 usually above the base of the mandibles, rarely on the front. 



The mouth is very important. Many larvae masticate their 

 food. In this case all the oral parts are at the opening- of the 

 mouth ; some larvae only suck their food, having the mouth very 

 small, scarcely visible and the oral parts are often very distant 

 from the opening of the mouth. 



The mandibles are always (horny) corneous and according to 

 the manner of feeding differently shaped. In rapacious larva? 

 they are sharply pointed, often dentate more or less prominent. 

 In those that masticate their food, they are stout aiid short, the 

 insides fitting to each other. 



The maxillae consist of several parts, the same as in the imago. 

 The basal piece is sometimes exceedingly developed, and supports 

 at its extremity two appendages, an inner and an outer one ; the 

 inner (maxillar lobe) is mostly one-jointed, in Carabidae and Ela- 

 teridae two-jointed ; the outer (maxillar palpus) usually three- 

 jointed. 



The labium, consists as in the imagines of mentum, ligula and 

 labial palpi. The mentum is frequently more or less connate 

 with the head, often fleshy, never so developed as to cover the 

 two-jointed palpi. The ligula is often wanting- or rudimentary. 

 (Bivprestis has mentum and ligula much developed). 



The last abdominal segment ends by a cylindrical anus, which 

 is used as a propeller. 



Stigmata, nine pairs ; the first beneath the mesothoracic seg- 

 ment (rarely under the prothorax), the other eight at the sides 

 of the remaining segments. 



CICINDELID^. 



These larvae are remarkable for the hook which they have at 

 the back of the fifth abdominal segment and by which 

 they hold themselves in the vertical holes, they dig in the 

 earth or in the sand where they wait for their prey. 



They have legs with six joints, the two claw r s being 

 moveable and four eyes on each side with the exception 

 of Amblychila, which has but one eye on each side. 

 Leconte says they are easily procured in spring, by plac-
