6 COLEOPTERA 



FAMILY CARABIDES. 



Mentum emarginate. Ligula prominent, nearly always furnished 

 with paraglossae. Maxilla slender, ciliated inwardly ; their external 

 lobe bi-articulate, palpiform. Mandibles in general moderate, unarmed, 

 or having few teeth on the inner side. Labial palpi three-jointed. 

 Antenna eleven jointed, usually filiform or setaceous. Posterior coxae 

 widened and prolonged at their inner extremity ; trochanters of the same 

 pair projecting inwardly ; tarsi five-jointed. Abdomen composed of six 

 segments, the three first connate. 



Mesothoracic epimera not reaching the middle coxae. 



Amarotypus. 



Bates; Entom. Mon. Mag., vol. ix.,/. 50, 1872. 



Corpore ovato Gen. Amaram simulans. Antennis articulis, 4 

 basalibus glabris. Caput postice crassum, retractum, oculis haud pro- 

 minulis. Mentum breve, leviter emarginatum, dente mediano brevi, 

 bifido. Palpi breves, robusti, articulis ultimis elongato-ovatis, ad apicem 

 sub-acuminatis, leviter oblique truncatis. Prosternum obtusum, haud 

 porrectum. Epimera metasterni nulla. Tarsorum maris articuli basalis 

 4 pedum quatuor anteriorum dilatati, subtus spongiosi, articulo quarto 

 eequaliter bi-lobato. 



The strange little Carabid forming this genus is distinguished from 

 the allied genera Migadops, Brachyccelus, Loxomerus, &c., by the four 

 dilated basal joints of the anterior and middle legs, and by the equality 

 of the lobes of the fourth joint. 



The species resembles an Amara to deception, and forms an 

 interesting addition to the Antarctic group Migadopintz, allied to our 

 northern Nebriance. but differing from them in facies and in the middle 

 tarsi being generally dilated. In form Amarotypus resembles Systolosoma, 

 but the hind coxae do not reach the side of the body, as in that still 

 more anomalous genus.
