Shorter and more robust than C. blattoides, the whole surface asperately 

 punctate, and clotlied with moderately dense, long-, reddish pubescence. The 

 thorax is sli<;litly broader than lonp:, with the base truncate, feebly narrowed 

 from tlie ba^e forwards; the lateral line is thrown ou to the dorsal surface from 

 the posterior angles until close to the middle of the anterior margin. The 

 elytral co>tae take the form of fine raised lines, the intervals being- flat, each 

 with tiiree reguLir rows of setigerous asperate punctures ; humeri obtuse, but 

 distinctly angulate. J\ves almost contiguous above, the front of the head more 

 uneven, with a broad transverse impression a.U'oss the clypeal constriction, 

 which extends upwards towards the eyes in the middle line ; this depressed 

 area, and the part in front of the eyes, strongly asperately punctate, leaving a 

 broad, smO(Uh area above the insertion of each antenna. The anterior femora 

 are rather more slender than the others.

This species is named in honour of the late J. Cliatanay. who fell in 

 action at Yermelles on October 15th, 1914. He was one of the younger 

 French entomologists, and had accomplished much sound and useful 

 work on this family of Coleoptera.

A NOTE ON THE SYSTEMATIC POSITION OF THE GENUS 

 TRETOTHORAX Lea (COLEOPTERA).

In describing Tretothorax cleistostoma Lea (Proc. 11. Soc. Victoria, 

 xxii, 1911, p. 211, pi. XXV, iig. 13), its author, being unable to include 

 it in any existing family of Coleoptera, was comj)elled to erect for it a 

 new family, Tretothoracidae, which he considered intermediate between 

 the Colydiidae and the Rhysodidae. 



Dr. Gestro, judging only from the description and figure, and from 

 its termitophilous habits, has assigned the genus to the Khysopaussidae 

 (Ann. Mus. Genova, xlv, 1911-13, p. 5, fig.) ; but with this family 

 {=^ Tenth r ion idae, subfam. Hhysopaussinae of Gebien in Junk's 

 " Coleopterorum Catalogus," 1911) Tretofhorax certainly has no 

 connexion. 



The heteromerous tarsi and closed anterior coxal cavities assign it to 

 the Tenebrionidae ; but the lack of visible connecting membranes be- 

 tween the postenor abdominal segments, and of visible trochantins to the
