Tribe XVI.— Panagseini. 

 Antennae slender arising under a distinct frontal ridge, three basal joints 

 glabrous, without fine punctuation and pubescence, but ciliate. Head usually 

 constricted behind the eyes and dilated to a semiglobular neck, front with two 

 supra-orbital setse. Eyes round, rather prominent, distant beneath from the buccal 

 opening. Labrum with four setse only. Maxillse small the inner lobe slender, 

 hooked at tip ciliate or spinous within, outer lobe stout, biarticulate, palpi elongate 

 the last joint triangularly dilated and inserted obliquely on the preceding, these 

 two hairy. Mentum emarginate, toothed at bottom, the basal suture distinct. 

 Ligula moderately prominent, bisetose at tip the paraglossse adherent and rarely 

 longer than it, palpi moderate in length the terminal joint triangular. Thorax 

 variable in form. Body not pedunculate, scutellum distinct. Elytra not margined 

 at base, sides narrowly inflexed, margin interrupted posteriorly and with an 

 internal plica. Prosternum not prolonged. Mesosternum' oblique, the epimera 

 very narrow. Metasternal epimera distinct, posterior coxse contiguous. Tibite 

 ciliate externally, the anterior emarginate within, the spurs distant. Tarsi slender 

 in our genera, the fourth joint bilobed in certain exotic genera. 



The males rarely have the anterior tarsi dilated. In our genera the first two 

 joints of the anterior tarsi are dilated and hairy beneath. 



Of late years authors seem pretty well in accord as to the limits of 

 this tribe. Lacordaire included Loricera which has already been dis- 

 cussed. To the tribe as left by the latter author Schaum ( Ins. Deutschl. 

 i, p. 318), added Tcjflus, and Disphrxricus which however is not included 

 by Chaudoir in his essay on the tribe (Ann. Belg. 1878). I have not 

 seen the latter genus in nature. Geohius included by Lacordaire is 

 excluded by Chaudoir for reasons which seem scarcely more than of 

 generic value. I cannot see any relation with Pelecium. 



Chaudoir in the characters of the tribe has the following paragraph : 



" Machoires crochues et tres ciliees en dedans, lobe inferieur a dernier 

 article court, tr^s large, comprime et termine par un petit crochet 

 ( excepte 'dans le genre Micrixyi).'" 



I can find no such character as that mentioned for the outer maxillary 

 lobe and if it did exist would be uniqiie in the tribe and extraordinary 

 in the entire family. 



The affinities of the tribe are not well marked in any direction, it 

 appears in fact to stand more nearly alone than any tribe of the present 

 sub-family, and I have already expressed the opinion that its affinities 

 with the Carabinae are rather through the Clivina? than the Cychrini. 

 I can see no reason for suspecting any relationship with the Chlaeniini. 



Two genera occur in our fauna which, difi^r in the following manner : 

 Clypeus prolonged beyond the base of the mandibles, the latter decussating, 



scissor-like Pauagseiis. 



Clypeus emarginate at middle, the mandibles stout, pincer-like Micrixys. 



The latter genus has the head not distinctly constricted but the neck 

 is of the same semi-srlobular form as in the former.
