386 Mr. M. Cameron on new Stapliylinidae 



TiNOTOMA, gen. nov. 



Mandibles rather stout, lightly curved, the right with a 

 strong tooth about the middle of the inner margin,^ the left 

 bifid at the apex, both at the base with a membrane furnished 

 with four large, stout, triangular teeth. Maxillary palpi 

 5-jointed, the first joint small, the second moderately 

 elongate, gradually enlarged towards the apex, the third 

 longer and a little stouter than the preceding, the fourth 

 much narrower than the preceding, parallel and about one- 

 fourth its length, the fifth scarcely narrower and about half 

 as long as the fourth, the apex rounded. Inner lobe of the 

 maxilla with moderately long and slender pectinations along 

 the inner margin ; outer lobe with the apex finely ciliate. 

 Tongue extending to the level of the apex of the second 

 joint of the labial palpi, rather short, broadly emarginate 

 nearly to the middle. Paraglossse distinct, finely ciliate. 

 Labial palpi 4-jointed, the first joint rather short, stout, the 

 second much shorter and narrower and twice as long as 

 the preceding, cylindrical, the fourth a little narrower and 

 one-fourth the length of the third, the apex rounded. 

 Labium broadly emarginate in front, antero-external angles 

 prominent. Temples finely bordered below throughout. 

 Mesosternal process narrow, pointed, extending nearly the 

 whole length of the inner margin of the coxse, which are 

 narrowly separated. Metasternal process short and bluntly 

 pointed, not meeting the mesosteruum. Tarsi 4, 5, 5. The 

 anterior pair with the first three joints short and equal, the 

 fourth as long as the three preceding together ; middle pair 

 with the first joint short, the second to the fourth gradually 

 increasing in length, the fifth nearly as long as the three 

 preceding together ; posterior pair with the first joint a 

 little longer than the second, the second, third, and fourth 

 equal, the fifth as long as the two preceding together. Claws 

 slender, lightly curved. Tibiae finely ciliate. Elytra not 

 sinuate. The facies of the insect on which this genus is 

 founded is that of a minute Tinotus. 



141. Tinotoma 7'ufotestacea, sp. n. 



Moderately shining, testaceous; the head and abdomen 

 rufo-testaceous, the 5th and 6th segments of the abdomen 

 pitchy. Antennae rather short and stout, testaceous, the 

 last three or four joints infuscate. Legs testaceous. 



Length 1'5 mm. 



Head suborbicular, the eyes large^ not prominent, their
