IRRORHOTIDES : A NliW GENUS OF ATEUCHIDiE. 117 



exterior margin, curved inwards at extremity, with four small 

 equidistant points or tubercles on the inner margin. Femora of 

 a uniform thickness, and not perceptibly thickened towards base. 

 Intermediate femora thickened in the centre ; tibiae short, termi- 

 nated in a sharp curved spine. Posterior femora thickened in 

 the centre ; tibiae rather long, narrow, and slender, more or less 

 three-sided, obliquely truncate at apex, terminating in a sharp 

 curved spur. Tarsi similar to Actuiophorus. Prosternal keel 

 ending in an obtuse point ; sternum with a deep sharply defined 

 depression down the whole length from the prosternal keel. 



FRYii, n. sp. 

 Colour dull black. Head wider than long, 6-dentate, with 

 the two centre teeth prominent, and the indentation circular ; 

 the remaining teeth are almost obsolete. Clypeus smooth, 

 slightly curved upwards in front, covered with very small and 

 fine punctures ; occipital ridges very small, and not produced 

 towards the centre of the head ; margins smooth. Antennae 

 black, club greyish. Thorax slightly convex, shining, thickly 

 punctured with fine punctures and small granules. The posterior 

 margin is curved inwards towards the disc, emarginate, and 

 finely but closely crenulate ; lateral margins produced to the 

 centre, with a number of long porrect reddish-brown hairs on 

 posterior portion. Scutellum obsolete. Elytra slightly duller, 

 with six striae on each elytron ; interstices rugose and covered 

 with some large irregular shallow punctures, which get more 

 shallow and smaller towards apex. Suture very distinct, smooth, 

 shining, and impunctate. Abdomen smooth, shining ; pro- 

 sternal keel shinmg and finely punctured on sides, smooth on 

 disc. Pygidium dull, slightly granulate. Anterior tibiae quadri- 

 dentate on exterior margin, with the apex thickened laterally at 

 tip, and terminating in a sharp fine spine ; the apex is curved 

 inwards into a large obtuse tooth. Inner margin with a number 

 of long reddish-brown hairs, and a small tuft of hairs on the 

 centre of the under side of the femur, and another small tuft at 

 the apex, on the upper side. Intermediate and hind tibiae covered 

 with thick reddish-brown hairs; femur and sides of abdomen 

 pubescent. Tarsi verticillated. L. c. 25 mm. 



Hab. Port Nolluth, S. Africa. (Type in coll. A. Fry.) 

 I have to thank Mr. A. Fry for the loan of the above interesting 

 and unique Ateuchid. The peculiar form of the thorax will serve 

 to distinguish it from its other allies. The form of the anterior 

 legs is very similar to Sebasteos, Westvv., and the cordate form of 

 the abdomen places it after Actinophorus, Creutz, and Sebasteos, 

 Westw. It seems a link, too, between the Ateuchites (proper) 

 and the Old World genera of Eucranides —Maematium, McLeay, 

 and Pachysomay McLeay.
