COLEOPTERA. 309 



■LORICERA, Lat., 



Is very remarkable. The antennae are setaceous and curved, with 

 the second and four following joints shorter than the last, and fur- 

 nished with fasciculi of hairs. The mandibles are small. The 

 maxillae are bearded externally. The labial palpi are longer than 

 those of the maxillae. The eyes are very prominent. The thorax 

 is nearly orbicular or cordiform, and widely truncated, with its pos- 

 terior angles rounded. The three first joints of the anterior tarsi 

 are dilated in the males(l). 



Patrobus, Meg. 



The antennae straight, filiform, without the fasciculi of hairs, the 

 fourth and following joints equal and almost cylindrical: the mandi- 

 bles of an ordinary size; the labrum forming a transverse square, 

 with the anterior edge straight. The length of the labial palpi does 

 not exceed that of those attached to the maxillae. The thorax is 

 cordiform and truncated, with the posterior angles acute. The two 

 first joints of the anterior tarsi are alone dilated in the males. The 

 eyes are less prominent than in the preceding subgenus, and the 

 neck is not so narrow(2). 



We will now pass to those Carabici whose anterior tibiae have no 

 emargination on the internal side, or which present one that begins 

 close to their extremity, or that does not extend on their anterior 

 face, and forming a mere oblique and linear canal. The ligula is often 

 extremely short, terminated in a point in the middle of its summit, 

 and accompanied by pointed paraglossae. The mandibles are robust. 

 The last joint of the exterior palpi is usually larger, compressed 

 into the form of a reversed triangle, or securiform in some, and 

 almost into that of a spoon in others(3). The eyes are prominent. 

 The elytra are entire or simply sinuous at their posterior extremity. 

 The abdomen, compared with the other parts of the body, is volu- 

 minous. They are generally large Insects, are ornamented with 

 brilliant metallic colours, run very fast, and are extremely carnivo-

(3) It is frequently more dilated in the males — a fact very evident in Procerus.
