dentate in middle, and the front trochanters armed ; its sur- 

 face also is very feebly punctured. In Raffray's Table*, it 

 would be associated with T. hunirralis (except that the head 

 could scarcely be called rounded), but it differs from the 

 figure of that species in having the head shorter, with more 

 prominent eyes, the middle tibiae armed, and the front pair 

 unarmed. 



Rytus insignicornis, n.sp. (Plate xvii., fig. 5). 



(J. Reddish-castanecms, legs souiewhat paler, palpi and tarsi 

 still paler. Wtih moderately long, and not very dense, pale 

 pubescence. 



II ((id of moderate size, deeply transversely excavated to- 

 wards the front, the excavation with a strong semicircular 

 backward extension at middle, so that the extension appears 

 to be margined by a strong, obtuse horn on each side ; with 

 a strong, curved elevation between antennae, the elevation 

 then narrowed and depressed posteriorly, and then with a 

 strong tubercle at its apex, which is slightly in front of and 

 between the obtuse horns ; with moderately distinct punc- 

 tures. Antennae with first joint rather short and stout, 

 second gently transverse, third and seventh each about twice 

 as wide as long; fourth, fifth, and sixth each more than 

 thrice as wide as long, and feebly concave on their under- 

 surface; fifth widest of all ; eighth almost as wide as seventh, 

 but much shorter ; ninth rather strongly, tenth moderately 

 transverse ; eleventh rather thin, slightly longer than the 

 three preceding joints combined. Froth ova. r widest near 

 apex, with moderately distinct punctures on sides, but feeble 

 along middle. Elytra almost as long as wide : punctures very 

 indistinct : each with two small basal foveae. Mcfastcrnum 

 moderately impressed. Abdomen gently flattened along 

 middle of under-surface. Le(js long: middle trochanters sub- 

 triangularly dentate. Length, 2 mm.
