200 On the Longicorn Coleoptera of Japan. 



Xylotrechus pyrrhoderus , n. sp. 



X. elongato-oblongus, niger, thorace globoso-ovato, rufo, grosse 

 retieulato-punctato, sparsim nigro-pubescente ; elytris regione scu- 

 tellari fulva, fasciisque duabus flavis, prima paululum obliqua (ad 

 suturam versus scutellum ascendente), altera longe post medium 

 recta. Long. 5-6 lin. 



Nagasaki ; Yokohama. 



Belongs to that section of Xylotrechus which has only the 

 marginal ridges of the forehead distinctly raised ; the whole 

 head is coarsely scabrose-punctate. The antennae are rather 

 short and much thickened from the fifth joint ; velvety black, 

 with the basal part inclining to piceous. The thorax is 

 oblong-ovate, as broad as the elytra, strongly convex and 

 rounded on the sides ; it is blood-red above and beneath ; its 

 vestiture consists in very short black bristles planted in the 

 large closely packed punctures. The scutellum and a patch 

 around it are tawny testaceous. The apex of the elytra is 

 obtusely rounded ; but the exterior angle is marked by a 

 strong pointed tooth. The legs are black ; all the femora 

 gradually thickened, not clavate. The mesosternum is red, 

 like the prothorax ; the metasternum and abdomen are deep 

 black, coarsely punctured ; the episterna and the second 

 (sometimes also the first) abdominal segment have a stripe of 

 whitish torn en turn. 



Clytus caproides, n. sp. 



P. caprce (Germ.) proxime affinis, at differt elytrorum humeris late 

 fulvo-testaceis etc. Valde elongatus, parallelus, nigro-fuscus, 

 fulvo-birsutus, fronte vittis duabus, thoracis marginibus anticis 

 et posticis, fasciisque duabus elytrorum (antica valde obliqua, 

 angulata, abbreviata) lsete flavis ; elytris humeris plaga magna 

 fulvo-testacea ; antennis et pedibus testaceo-rufis. Long. 7| lin. 



Two examples, Ipongi. 



Of very similar shape to C. capra ; elongate and parallel. 

 Body and limbs rather less densely clothed with long 

 pale hairs. Thorax globose-ovate, rather narrower than in 

 C. capra ; very densely granulate-punctate. The humeral 

 tawny patch of the elytra is triangular, obliquely defined 

 posteriorly, and not extending to the humeral margin ; it 

 encloses in the middle a dusky spot (and there is no oblique 

 yellow linear fascia as in C. capra) ; behind this, on the 

 margin, is a short yellow streak, as in C. capra ; the oblique 

 yellow stripe towards the middle is much shorter than in 

 C. capra, and is bent in the middle ; the posterior belt is much 

 widened towards the margin ; and there is no yellow apical
