 A NEW COLEOTICHUS FROM SAMOA 



DESCRIBED BY 



Dr. H. SCHOUTEDEN. 



During a visit to the Leyden Museum I found in the 

 collection a Coleotichus from the Samoa-islands which on 

 examination appeared to represent a new species of this 

 genus. When preparing my Monograph of the Coleotichus 

 (Annales Musei natioualis Huugarici, III, pp. 317 — 361, 

 pis. Vlll et IX, 1905) I did not see any material from the 

 Samoa-islands and it is quite interesting to find the genus 

 is represented there by a new species. In my opinion this 

 is certainly one of the intermediate forms which are to be 

 found between the splendid C. BlacTchurni from Hawaii 

 and the australasian Coleotichus. 



This new Coleotichus was collected at Savaii, Samoa, by 

 Mr. W. von Billow, after whom, at the request of Mr. Ritsema, 

 I have named the species C. Biiloici. I append here a short 

 description of it. 



Coleotichus {Coleotichus) BCdoioi, sp. n. 



One of the largest known species: cf 19,5 — 20,5 mm., 

 9 22— 23 mm. 



By most of its characters closely resembling C. excellens 

 Walk., from Australia and New Caledonia. The differences 

 are the following : 



Body above dark piceous, tinged with green ; punctuation 

 usually shining aeneous ; margins of head and lateral mar- 

 gins of pronotum testaceous; following parts somewhat
