INSECTA. 545 



Family LXIII. Carabicina (Adephaga terrestria, Carabici and 

 \Cicindeletce LATR.). Palps six; maxillae with double palp (ex- 

 Iternal lacinia palpiform). Mandibles exsert. Maxillae incurved at 

 'the apex. Antennae thin, filiform. Body mostly oblong, with 

 thorax cordate, oval or quadrate. Abdomen composed of six seg- 

 ments, the three first connate. 



A numerous family, in which DEJEAN in 1839 distinguished 

 nearly 2,800 species, and which with LINNAEUS consisted of two 

 genera Carabus and Cicindela numbering together, in the last 

 edition of the Sy sterna Naturce, only 57 species.

Phalanx I. Ligula porrect (often augmented by lateral ap- 

 pendages or paraglossae). Apex of maxilla (with few exceptions) 

 without hook distinct, articulate. Labial palps with three joints, 

 set upon labium by means of a peduncle elongate, immoveable. 

 Head not broader than thorax, mostly narrower. Many species 

 ipterous. (Carabicina in the stricter sense, Carabidce LEACH, 

 WESTW.) 



Running-beetles, earth-beetles. Most of the species live under- 

 ground, under stones, under bark of trees. They run very swiftly. 



The oasophagus is at its origin narrow, but it soon expands 

 largely ; to this crop succeeds the muscular stomach and a long 

 narrow stomach beset with villi, at the inferior extremity of which 

 the four vessels secreting urine are implanted. The small intestine 

 is short, the rectum oval and wide. RAMDOHR, op. cit. pp. 82 84,

The larvae have a longitudinal body, divided into twelve rings, 

 without counting the head. The first ring (prothorax) is horny ; 

 the last has two conical, horny, or membranous appendages. The 

 head has strong jaws, six simple eyes on each side, and two antennae 

 consisting of four joints. The six feet are of moderate length, with 

 two hooklets at the extremity.
