80 Mr. David Sharp on the 



together. The antepenultimate joint of all the tarsi 

 simple. 



146. Sten(2sthehis siinioides. Brunneus, subopacus, 

 capite, thorace, elytrisque crebre fortiter punctatis, abdo- 

 mirie omnium dense subtilissiraeque puuctato, antennis 

 pedibusque testaceis. Long. 1^ lin. 



Mas, abdomine segmento 7° ventrali longitudinaliter 

 fisso, 6° late triangulariter impresso. 



Antennae rather short, extremely slender except the 

 basal joint (or two joints); the 10th joint elongate, stouter 

 than the 9th, 11th joint also elongate and stouter than the 

 10th. (I assume these organs to be 11 -jointed, but have 

 quite failed to get a clear view of the four or five basal 

 joints.) Palpi pale yellow. Head large, with the eyes 

 a little broader than the thorax, the front even, rather 

 coarsely and closely punctured ; the eyes moderately large, 

 placed very near the back of the head, coarsely facetted. 

 Thorax narrower than the elytra, longer than broad, con- 

 siderably narrowed behind ; it is densely and rather coarsely 

 punctured, even and unimpressed. Elytra broad and 

 short, considerably shorter than the thorax, rather coarsely 

 punctured, a little shining. Hind body very stout, cylin- 

 dric, more elevated than the other parts ; it is extremely, 

 finely and densely punctured and shining, and its pubes- 

 cence is so fine and short as to be almost invisible. This 

 curious little insect reminds one of the Simii, but has no 

 outstanding seto3. 



Four specimens, found on INlitzuyama, March, 1870. 

 Also from North China. 



147. Stenus tenuipes, n. sp. Nigro-subchalybeus, dense 

 profundeque punctatus, subtiliter albido-pubescens, palpi s 

 articulo primo testaceo, 2" fusco-testaceo, 3° fusco-nigro ; 

 elytris macula sat magna fulva. Long. 2^ lin. 



Of the slender form of S. higuttatus, but with the femora 

 thinner, the spot on the elytra larger, and the thorax more 

 cylindric, and the palpi not quite so darkly-coloured. 

 Antenna long and slender, generally pitchy in the middle. 

 Head deeply excavate, as in hirjuttatus, the raised line at 

 the bottom of the excavation more distinct. Thorax 

 narrow and elongate, with a short, but deep and distinct, 

 channel or impression in the middle at a considerable dis- 

 tance from the ])ase. Elvtra a little longer than tlie thorax.
