ON CALANDRINAE. 147 



NOTE XIV. 



A NEW GENUS OF CALANDRINAE 



CHAKACTEEIZED BY 



C. RITSEMA Cz. 



Having received from Mr. A. L. van Hasselt of Padang 

 Sidempoean , among some other interesting beetles from 

 Sipirok (North West Sumatra), a couple of a beautiful 

 Calandrid of the group Rhynchophoridae , viz. Macrocheirus 

 spectahilis Dohrn , I carefully examined the materials of this 

 group in the Leyden Museum , and this examination con- 

 vinced me of the necessity of dividing Schönherr's genus 

 Cyrtotrachelus in two genera. 



The following table will clearly show the distinctive 

 characteristics of the genera of the first division of Lacor- 

 daire's group Rhynchophorides (Genera des Coléoptères. 

 Tom. VII. p. 271): 



a. Elytra distinctly narrowing backward, conjointly emar- 



ginate at the end. 

 h. Anterior coxae rather widely separated, 

 c. Joints of the funiculus slender, its 2nd joint much 

 longer than the 1st. Rostrum curved. Scutellum elon- 

 gate lanceolate. The metasternum very strongly con- 

 vex in its anterior half. — (ƒ. Anterior tibiae fringed 

 with long hairs at the under margin of their apical half. 



Macrocheirus Schönh. 



cc. Joints of the funiculus not or but little longer than 



broad, its 1st and 2nd joints about equal in length 



to each other. Rostrum straight. Scutellum acutely 



triangular with concave sides. The metasternum not
