Trib. Lebiidse. 

 Anchista. n. g N. 



Corpus depressum, ovatum. Mentum deute niaguo obtuso, lobis 

 parum breviore, his extus rotundatis, apice acuminatis. Palpi ro- 

 busti, maxillares art. ultimo magno ovato, apice obtuso, labiales art. 

 ultimo valde securiformi. Ligula cornea apice obtuse acuminata, 

 labri marginem anteriorem attingens. (Paraglossse a me non dis- 

 secta3.) Labrum trausversim quadratum. Mandibulae simplices apice 

 arcuata3 et acuminata. Antenna3 robustse art. 1° mediocri, 2° brevi, 

 3° quarto paulo longiore, 4-10 subsequalibus, 11° penultimo parum 

 longiore. Thorax longitudine latior, angulis anticis rotundatis, me- 

 dio obsolete angulatus, basi angustatus, angulis rectis. Elytra apice 

 quadrate truncata. Pedes robusti tarsis art. 4° profunde bilobo, 

 unguibus fortitor pectinatis. 



12. Anchista modest a. N. 



A. brunneo-testacea, elytris (maculis 2 obsoletis subhumeralibus 

 exceptis) obscurioribus abdomine piceo. Long. corp. 4 lin. 



Caput fronte medio leviter uniimpressa. Thorax linea media 

 longitudinali divisus. Elytra apicem versus parum dilatata, striato-

The characteristics of this new genus are those of the g. Calleida 

 (between which and Cymindis I place it) excepting the ligula which 

 in this case is obtusely acuminated, the last joint of the maxill. 

 palpi which is obtuse at the apex, and the thorax which is not as in 

 Calleida longer than broad, but the reverse. Prom Cymindis it 

 would differ principally in the deeply bilobed 4th tarsal joint, and in 

 some other minor points, but it is difficult to say what the true 

 characteristics of this genus (which appears from this reason to 

 require a careful revision) are, if even Lacordaire uses the particle
