fellow as from the inner edge of the eje, between the inner edge of the eye and the 

 black point a subquadrate black spot. Face pale yellow, with a brown line from the 

 base of the antennjae to the apex of the lorse ; frontal suture distinctly angled near 

 the base of the aiitennaj, from thence to the apes straight, deeply impressed, and 

 longer than the width of the frons between the eyes. Setal plate of antennae very 

 narrow. Pronotum yellowish-brown, with bluish-white spots, behind each eye some 

 irregular dusky markings and a few black spots, sometimes with a bluish-white 

 middle stripe. Scutellum greyish-yellow, a black triangle on each side at the base, 

 two points on the disc, and sometimes a middle stripe rust-brown. Elytra pale 

 brown, a spot at the apex of the anal vein, about three spots on the brachial veini 

 and an irregular curved transverse band commencing at the apex of the clavus and 

 scarcely reaching the costa, white ; veins dark brown, punctured, on the pale parts 

 white. Legs pale yellow. 



? . Resembles the <? , but the crown and upper part of the face are marbled 

 with dark brown ; there is a large fuscous tract on the forehead ; the subquadrate 

 black spot next the eye is frequently wanting ; the pale middle-sti'ipe on the pro- 

 notum has a tendency to be more evident ; and the dark triangles at the base of the 

 scutellum are rust-brown, 



I have examined sis males and nine females, taken by Mr. W. 

 West off sallow at Oxshott and Wisley, at various times, and com- 

 pared them with Kirschbaum's types ((^, ? ), most obligingly lent to 

 me for that purpose by the Director of the State Natural History 

 iVIuseum at Wiesbaden. Kirschbaum says of the elytra, " ?««Y den 

 gewohnlichen zwei unterhrochenen Querbinden,'' but apart from this 

 discrepancy, for which one cannot account, his description agrees 

 admirnbly with his type-specimens. The latter ate evidently imma- 

 ture, and still show that the eyes were red during life. 1 believe, how- 

 ever, that this colour of the eyes is due to immaturity, as it is present 

 in one of Mr. West's examples, which, like the types, is immature. 

 Although described in 1868, this species remains but little known. 

 Paul Low (Verb. z.-b. Ges. Wien, 1885, p. 343) said that a speci- 

 men of /. signatus, Fieb , in his collection determined by Dr. Puton 

 agreed well with the original description of I. rufilans, and therefore 

 the two species were identical ; but this view has not been adopted 

 by later writers, who put Kirschbaum's insect, quite erroneously, as a 

 synonym of /. eltgans, Flor. It appears to me that Melichar's figure 

 of the elytron of /. poscilus (Cicad. Mitt, luir., t. viii, f. 5) might 

 well have been taken from a specimen of /. rutilans.
