narrowed a little above the ocellus and slightly anlcate below it, the 

 fasti^ium shallowly sulcate; antennae ferrujjinous. Pronotuni witli 

 the hiiMl margin feebly einarginate, the disk nearly uniform in color, 

 uat with tlie lateral lobes sometimes lighter and the metazona sonu'- 

 times longitudinally combed with obscure luteous, the :dteral lobes 

 mostly of the color of the disk or darker, bnt their lower portion, both 

 on ])rozona and metazona, with quadrate patches of didl luteous or 

 flavous, forming a broken band sliglitly separate from the lower mar- 

 gin. Prosternal spine quadrate, brief, appressed, broadly truncate. 

 Tegmina ovate, less than twice as broad as long, their inner edg« > 

 8e[)arated by half the widtii of the ])ronotum, of the color of the upper 

 surface. Fore and middle legs dull ferruginous; hind femora ferrugi- 

 lums, the carinae, lower margin of the outer face, and lower face 

 tiavous, on the last often strongly tinged with red; hind tibiae pale red, 

 the spines, except at base, black. Supraanal idate of male triangular, 

 acutely angled at tip, the lateral margins a little elevated, within them 

 the surface tectate, bearing at the summit of the ridge a deep sh '- • 

 sulcus fully two-thirds the length of the plate, the ridge fading beyouv. 

 furcula consisting of a pair of basally approximate, short, triangular, 

 pointed teeth, diverging at nearly right angles; cerci long and very 

 slender, tapering in the basal tliird, beyond lamellate, etiual nearly to 

 the tip, incurved gently and downcurved as gently, feebly twisted, tlie 

 apex acutangulate below by the sloi)e of the upper margin, somewhat 

 longer than the supraanal plate, pilose; iufracercal plates moderately

Length of body, male, 18 mm., female, 23.5 mm.; antennae, male, 5.1 



n., female, 6 mm.; tegmina, male, 3.25 mm., female, 4 mm.; hind fern 

 ora, male, 10,5 mm., female, 12.75 mm. 



Three males, 2 females. Mount Orizaba, Mexico, W. S. Blatchley; the 

 saine, 11,500 feet, March (L. Bruner). Originally described from tht 

 same mountain as collected by M. Aug. Salic "au pied de la niegc." 

 Mr. Ulatchley informs me that at the time of his visit the snow line 

 was at 15,000 feet, and adds that he took a single specimen of the specie^ 

 at 13,500 feet, "a very few individuals may have been taken as low as 

 9,000 feet, but the species was common only between 10,000 feet and 

 12,000 feet; above 12,000 feet scarce." 



According to statements in the daily press,^ Orizaba, which is o 

 volcanic origin, showed signs of a ^" lewal of activity early in Marcli. 

 1895, when hot ashes were ejected, the snow disai)])eared from the sum 

 mit and the vegetation of the ui»per part of the mountain was buriHii 

 Possibly this means the extinction of Paradichroplus mexicanus. 



The following description of the living insect, made upon the sjtot. 

 has been kindly sent me by Mr. Blatchley: Pronotum of male a>i 

 gray tinged with yellow, especially along the median line; sides v. 

 pronotum with a brownish strii^e ou upper half, bordered below witl
