82 ME. DAVID SHAEP OlS" 



Cautomus, noY. gen. 



Caput minutum, palpis exsertis. Antennse 10-articulatse, clava elongata, 

 quasi divisa. Prosternum longitudinaliter compresso-carinatum. Pedes 

 posteriores sat distantes. 



This genus is well clistinguislied by the minute head, in strong 

 contrast with the ample thorax, and the palpi placed at the front 

 of the mouth and more than usually exserted, as well as by the 

 peculiar carination of the prosternum along the middle ; this 

 carina extends the whole length of the prosternum, and projects 

 scarcely at all behind the coxae, its extremity replacing the pro- 

 sternal process. All the femora are rather large, the anterior 

 pair being decidedly larger than the others. The middle coxae 

 are nearly contiguous, the metasternum rather short ; the first 

 ventral plate in the middle nearly as long as the two following 

 together. The tibiae are somewhat dilated externally, so as to be 

 slightly angulate some distance above the apex. 



Cautomtjs HTSTEicTTLirs, n. sp. (Plate III. fig. 10.) 



Fusco-rufus, opacus, setulis truncatis, erectis, pallidis conspicue vestitus; 

 prothorace densissime rugoso-punctato ; elytris dense obsolete sculp-- 

 turatis. Long. 2 raillim. 



Antennae with elongate acuminate club, which, owing to the 

 apical half being pubescent, appears to be divided across the 

 middle. Thorax strongly transverse, the sides greatly narrowed 

 towards the deflexed front angles ; the surface very dull, owing 

 to extremely dense punctuations, the interstices of which can 

 scarcely be detected ; the lateral margin undulate behind, the 

 base with a short indistinct excision at the angle. Elytra with 

 a dense but very indefinite sculpture, the interstices of which are 

 to be distinguished as a series of very minute, irregular, shining 

 spaces, and provided with perfectly regular series of short, stiff, 

 upright setae. The thorax also bears similar setae, but they are 

 less distinct on it except at the margins. 



This was met with in fifteen examples at Tagami, near Nagasaki, 

 in the spring of the year 1881. This and the next species were 

 taken in the centre of a large rotten fir, which measured many 

 ieet in circumference, and was probably more than 300 years old. 



TnTEODEEUS, nov. gen. 



Corpus minutum, convexum, fortiter sculpturatum. Antennae 8-ai'ti- 

 culatse, clava rotundata, uniarticulata. Prosternum utrinque maxime 

 excavatum.
