the Rev. F. W. Hope nor Dr.Burmeister t«^ acquainted with the 

 veritable male of Erichson's species, which is now described for 

 the first time, and which differs essentially from C. cav'ifrons (var. 

 max.), Hope, by its broader and more convex form, the highly 

 polished dorsal patch on the elytra, and in the structure of the 

 mandibles, which in the insect now under consideration are some- 

 what broader, strongly curved at the apex, destitute of the flat 

 basal tooth, and instead of the group of subapical teeth only, as 

 in C. cav'ifrons, are armed with a stout tooth placed a little above 

 their centre, with four or five smaller ones between it and the 

 apical tip ; some of these teeth, however, may be more properly 

 called nodose elevations. The anterior tibiae moreover are straight, 

 and not curved as in C. cav'ifrons. 



The female is equally to be distinguished from that of C. cav'i- 

 frons by its more robust and convex form ; the anterior tibiae are 

 considerably more dilated, their outer edge also strongly denti- 

 culated ; the four posterior tibiae, like all the females of this genus 

 (with the exception of C. cavfrons), are armed with a single 

 spine.

The only two specimens of L. tenuipes^ Hope, with which I am 

 acquainted are in the Hopeian Collection and the British Museum, 

 and were obtained by Mr. Cuming during his visit to the Philip- 

 pines ; after careful examination, I have satisfied myself, from the 

 general sculpture of the head and the short strongly-punctate 

 mandibles, that both these specimens are females ; but from the 

 remarkable slenderness of the anterior tibiae, and from the absence 

 of spines on those of the four posterior legs, they have somewhat 

 the appearance of males with short undeveloped mandibles. The 

 specimen described by Mr. Hope is somewhat darker than that of 

 the British Museum, assimilating more in colour with the male, 

 which is chestnut-brown. While, on the one hand, the unarmed 

 tibiae of the four posterior legs would assign tenuipes to the genus 

 Odontolabis, in which Mr. Hope placed it, its slender fore tibiae 

 and general structure of body place it indubitably with those in- 

 sects which belong to the genus Cladognallius, and I am strongly 

 inclined to believe that it is the % of C. cavifrons.
