172 Mr. G. Lewis on the Pyrochroidse of Japan. 



and one rather deep and broad before the scutellum ; scutellum 

 posteriorly semicircular, black and opaque, like the elytra, 

 the latter rugose and moderately dilated behind ; legs black 

 with yellow claws. The female has the head transversely 

 convex between the eyes, a slight longitudinal ridge between 

 the antennge and a small boss-like elevation on each side close 

 to them ; the epistoma is flavous and the palpi black. 



Whether this last character is really sexual or whether the 

 coloration is inconstant in the species must remain at present 

 uncertain, as I have but one female. 



Found by sweeping under brushwood in June on Omine 

 in Yamato, and at Chiuzenji. Four examples. 



I have one more species of Pyrochroa from Miyanoshita 

 which is unique, and I do not describe it. Its head is rather 

 thickly punctured. 



Pyrochroa rufula. 



Pyrochroa rufula, Motsch. Bull. Soc. Mosc. 1866, p. 173, 



" Statura et color Pyrochroa pectinicorni, sed major. Oblonga, de- 

 pressa, opaca, supra rufo-coccinea, pubescens, corpore subtus, 

 fronte, ore, oculis, an tennis subserratis, pedibusque nigris ; tho- 

 race transverse, longitudinaliter triimpresso ; elytris thorace latio- 

 ribus, postice subdilatatis, nervis vix distinctis. Long. 3^- 1, 

 (about 7 miU.) lat. 1| 1." 



The measurements given above are less than those of P. 

 pectinicornis ; but the diagnosis expresses a contrary state- 

 ment. 



ScMzotus ruhricollis. 



Elongatus, subparallehis ; fronte in medio longitudinaliter carinata 

 utrinque valde excavata ; elytris thoraceque rufis, L. 9 mill. 



Elongate and posteriorly scarcely dilated ; head between 

 the eyes transversely convex and sparsely puncticulate, the 

 convexity being broadest close to the eyes ; the region before 

 the eyes is deeply excavated, with a polished longitudinal 

 ridge in the centre of the excavation which terminates before 

 the interocular raised or convex portion, and at the point of 

 termination there is a triangular excavation deeper than that 

 of the sides ; bordering the carina the head is more or less 

 reddish ; the neck is red and somewhat coarsely punctured. 

 Thorax uneven, a little raised in two portions behind the 

 neck with similar raised parts before the scutellum; the 

 raised portions are a little polished. Scutellum a little
