have much doubt \vhether the immature specimen in which T 

 found the character that I mentioned as those of the male could 

 even with maturity have reached the dark colors described as 

 those of novicum. On the whole, therefore, it will be best to 

 consider the authenticity of my statement of the sexual characters 

 of the male of S. novicum as needing confirmation.

SCIATROPHES (gen. nov. Scaphidiidarum). 

 Oculi minores, sat convexi, integri; caput antice elongatum

 subtilibus 7° quam hi manifeste crassiori parum longiori 8° 

 quam 7^"' sat breviori sat graciliori 9° — IP quam 7°^ parum 

 longioribus sat crassioribus (clava laxe articulata, modice 

 perspicua) : scutellum baud manifestum ; elytra postice 

 truncata, abdomen baud tegentia ; prosternum ante coxas 

 brevissimum ; coxae anticse contiguse, intermedise inter se 

 modice separatee, posticse inter se sat late distantes ; meta- 

 sterni episterna angusta ; abdominis segmenta basale elon- 

 gatum, 2''™ — 4""'" brevia, 5"™ elongatum conicum ; pedes 

 modici, tarsis sat brevibus 5-articulatis, posticis quam tibise 

 dimidium parum longioribus. 

 The species for which I propose this new^ generic name is near 

 Scaphiso7na but cannot be placed there on account of its much 

 shorter tarsi, and much narrower metasternal episterna. Its 

 antennae, moreover, are of structure somewhat different from 

 those of any Scaphisoma known to me. Their club is five-jointed 

 strictly speaking, but its first joint is so slightly enlarged in 

 comparison with the apical three, that to a casual glance it 

 seems to be only three-jointed. The eyes are smaller and more 

 convex than in Scaphisoma.
