CHLAMYDOPSIS FORMICICOLA King, var. DARWINENSIS 



var. nov. 



A specimen from Darwin is -tructurally so close to some cotypes of 

 C. foniiicitola that I cannot regard it as representing more than a variety of 

 that species; but it differs in. several respects; on the cotypes the striation of the 

 vertical side of each elytron is everywhere strong, and is conspicuously directed 

 towards the opening behind the epaulette ; on the Darwin specimen the striation 

 is nuich less strong, and abo\e and just below the opening is altogether absent, 

 or traceable with difficult}', the inner (liscal ridge on each elytron is acute, and at 

 its apex, still as a distinct narrow ridge, it curves round and abruptly terminates 

 half-way to the outer ridge, and about one-third from the apex: on the cotypes 

 the inner discal ridge is much less acute posteriorly, and at its apex is obtusely 

 connected with a wide feeble ekwation ; the punctures on the prosternum are 

 also less conspicuous than on the cotypes,

]\lr. W. du Pioulay has recently taken, in nests of Hctotoiiniia iiu'tallicuin 

 near Sydnev, two specimens of this species. l)Ut they ditter from the type in being 

 paler, dark castaneous-l)rown with the elytra and legs paler, and one of them has 

 the serrations at the apex of the prothorax more pronounced (pi. ix. fig. 2). 

 The antennae on both are closely fitted into cavities in the head, all parts but the 

 outer portion of the first joint being concealed. At the side of each antenna 

 (the corner of the head and prothorax) there is a depression allowing a small
