antennae, are two small spaces, slightly darker than their surround- 

 ings, and with what (under a quarter-inch power) appear to be 

 facets. It is quite possible, however, that these are really slight 

 granular elevations of the derm. They cannot be seen until the 

 head has been removed. Of this species Capt. Broun writes me : 

 " I have made two examinations of the head from above and 

 below, using half-inch lens in the microscope, and a good Codding- 

 ton glass. There may be seen minute, rather distant, granules, 

 which cannot be distinguished from ordinary sculpture. I possess 

 three specimens, one mounted on its back with the head exposed; 

 all were examined." Of his P. lobatus he says : "My mounted 

 specimen shows no indication of eyes, but I cannot remove the 

 head without spoiling the type." 



Family CLERTD^E. 



Pelonium Austral i cum, n.sp. 



(Plate xviii., fig.7.) 



Black; muzzle and a curvilinear triangle on lower surface of 

 head, prothorax, legs (tips of femora, apical half of tibiae and the 

 tarsi excepted), basal third of antennae, and basal joints of palpi, 

 more or less flavous. Clotlied with straggling yellowish pubescence 

 or hair. 



Head transverse, with prominent eyes, black portion (both 

 upper and lower) densely and rather coarsely punctate. Antennas 

 with 1st joint stout, as long as 2nd and 3rd combined, 2nd stouter 

 than but about as long as 3rd, 6th-8th very short, 9th-10th each 

 strongly forked and each about as long as 2nd-8th combined, 11th 

 slightly longer and stouter than 10th. Prothorax at apex 

 slightly narrower than head across eyes, sides slightly incurved 

 near apex, then rather strongly dilated to beyond the middle, and 

 again diminishing to base; basal margin narrowly raised, with 

 rather large scattered punctures, becoming dense on sides. 

 Scutellum transverse. Elytra not much wider than prothorax, 

 coarsely and rather densely punctate, the punctures becoming 

 very small and less numerous posteriorly. Mesostemum coarsely
