XXIV. Descriptions of New Species of the Coleopterous 

 genus Callirrhipis {RhipidoceridcB) in the 

 British Museum. Bj Chas. O. Water- 

 house. 



[Kcad November 7th, 1877.] 



The determination of a species of Callirrhipis from the 

 Andaman Islands lias led me to examine the specimens 

 of this genus in the British Museum Collection. I have 

 found among them numerous undescribed species which 

 are here characterized, and I have also made the following 

 notes. 



The males are always more or less pubescent above, and 

 the antennas are at least half the length of the entire 

 insect, and with long slender branches, the length of 

 which appears to vary slightly in the same species. The 

 male organ is short, rather flattened, and presents at the 

 apex three points, the two latei'al ones slightly curved, 

 acuminate and embracing the central smaller one. 



All the females of species known to me are destitute of 

 pubescence above ; the antennae are about as long as the 

 head and thorax taken together, and have only short 

 branches. The ovipositor is nearly as long as the entire 

 abdomen, and the apex (which is frequently visible) pre- 

 sents two sharp points. 



The small horny pieces ("piece jugulaires") situated in 

 ligament between the head and thorax seem to be for pro- 

 tection to the eyes when the head is withdrawn into the 

 thorax ; they are slightly woolly on the surface next the 

 eye. It is strange that they should have only been 

 observed in the American species. I have found them in 

 all the species in both sexes. 



I have not seen the female of any American species, 

 and have only been able to match the sexes of one species 

 from Borneo, that Avhich I here name Callirrhipis dis- 

 similis ; but of the chai'acterized species known to me 

 from description I have little doubt that C. Championi of 

 "Westwood will prove to be the female of C. Templetoni 

 of the same author. C. orieiitalis, Castclnau, will pro-
