finer structure of which I have been unable as yet to make 

 out. I could find no trace of a hypodermis between the 

 retinal cells and the cuticle. 



The eyes have completely lost all traces of a lens. The 

 chitin is thinned away over them, so much so that very 

 minute eyes are little more than plugs of pigment in deep 

 chitinous pits (fig. 2).

 the Galeodidaj is ready for publication. 



LXII. — Description of a new Longicorn Beetle of the Genus 

 Diaxenes, tcMch has been found injuring some imported 

 Orchids. By C. J. Gahan, M.A. 



The genus Diaxenes^ Waterh., has up to the present included 

 but a single described species, and with regard to the locality 

 of that species nothing very definite was known. The one 

 example of D. Taylori^ AVaterh. (Ann. c^ Mag. Xat. Hist, 

 ser. 5, vol. xiii. p. 128), which the British Museum contained 

 ■was found in the Koyal Nursery, Chelsea, where it was 

 gnawing off the stems of an orchid from ManiUa, of the genus 

 Fhalanopsis. Three additional examples are, I tind, contained 

 in the Pascoe collection ; these are ticketed " Moulmein," 

 though on what authority is not stated, and cannot now be 

 ascertained. My reasons for giving Burma as the habitat of 

 the new species are stated below. This new species has also, 

 like its congener, exhibited a special taste for orchids, espe- 

 cially those of the genus Dendrobium. 



Diaxenes dendrobii, sp. n. 



Fortitcr pnnctatus ; pube fulvo-bruunca sat dense vcstitus ; pro- 

 thorace clytrisipie albescentc lineatis, hueis elytrorum doi"s;ilibu3 

 sinuatis ; scutello fusco, puucta centrali ct limbo exteruo albis; 

 antennis griseo-t'ulvis, articulis 4" ad (i""" plus uiinusve iufuscatis.

Strongly and rather closely punctured, with the punctures 

 partly concealed by the close pubescence ; this is mostly of a 

 fulvous brown or drab colour, but there are darker brown 

 areas on some of the intersi);;ees between the whitish lines ; 

 the ])ronotum bears three white lines, one median and one 

 towards each side, the two latter converging anteriorly. Each
