MKI.AMJliYlDAK. I I ■') 



Elytra as hioatl as thorax at the base, giaduallv attenuate behind the 

 middle, with actite but not divergent apices. 



Eyes widely distant above, prominent, with distinct facets; they 

 are large above, but taper downwards without any definite emargina- 

 tioji. Antennae inserted before the middle of the eyes; l)asal joint stout, 

 cylindrical, nearly as long as the elongate 3rd; 2nd short yet longer 

 than broad, 4th longer than 3rd, 5th and 6th elongate but shorter than 

 4th; 7th and 8th distinctly longer than bi-oad, narrowed towards the 

 base; 9th and 10th obconical, rather broader but a little shorter than 

 the preceding ones, the terminal joint broadly oval or subrotundate. 

 Terminal joint of maxillary palpi subtriangular or broadly cultriform. 

 Legs robust; tibiae not aspei-ate externally, the intermediate longest, the 

 posterioi- short, almost elongat<:'-triangular, hardly longer than their 

 equal, distinctly pectinate spurs, these nearly attain the extremity of 

 the long basal joint of the tarsi, the terminal three are well developed 

 and slendei- and together barely the length of the 1st, with slender 

 claws. Anterior taisi dilated, basal four joints cordiform, the 1st 

 longest, 2nd and 3rd transverse, penultimate deeply emarginate above 

 and below and thei'efore sublobate, the terminal moderately slender, 

 inserted near the base of its predecessor and twice its length; pen- 

 ultimate joint of the intermediate pair with moderately elongate lobes. 



Prosternal process prolonged to the extremity of the coxae, the 

 mesosternal cariniform in front. Flanks of prosternum distinctly de- 

 fined. Trochanters present. 



The entire absence of the scutellum at once separates this from all 

 its allies, whilst the differently formed eyes, antennae, and tarsi dis- 

 tinguish it from Orchesia. In Neorchesia the eyes are flat. 



3431. Allorchesia validipes sp. nov. 



Nitid, elytra subopaque, and covered with depressed, slender, 

 greyish-yellow pubescence, and bearing also, towards the extremity 

 paiticularly, a few slendei' erect setae; body castaneo-rufous, legs and 

 antennae somewhat fulvescent, anterior tarsi testaceous. 



Head moderately closely, rather finely, yet quite definitely punctate. 

 Thorax finely margined laterally behind the middle, a little rounded 

 there, so that the base is not quite as broad ; its sculpture as close as that 

 of the head, the punctures not as well defined, and with a tendency to 

 become transformed into fine irregular rugae near the sides. Elytra 

 rather wider near the ]iostei'ior femora than elseAvhere, with slightly 

 convex, acuminate apices, which are narrowly separated; their sculpture 

 neai- the shoulders is similar to that near the sides of the thorax, but 

 it is finer elsewlieir ; the sutural striae are very fine at the base, but 

 well marked behind ; the pubescence is feather-like near the middle. 



Underside a little shining, reddish-chestnut, the abdomen paler, 

 finely i^unctured, with fine yellow pubescence, its basal segment 

 bipunctate between the middle and each side, the breast closely punctate.

Ohx, — 32.")8, also uni(|uc, should be transferred to this genus, not 

 only on account of siinilai'ity (^f structure, but also ':.:-cause there is no 

 scutellum. The insect itself, now Allorchesia guinnessi, is a good deal 

 snuiller, with more slender legs and less dilated anterior tarsi; this last 

 character, to some extent at anv rate, mav be onh' sexual.
