British species of Corticaria. 135 



(excepting tlie legs and antennae), sometimes testaceous. The 

 pubescence is of a dirty white hue. 

 Moderately common. 



2. Corticaria crenulata. C. oblonga, convexa, longius pubescens, 

 nigro-picea, antennis pedibusque flavescentibus ; thorace 

 subrotundato, coleopteris angustiore, lateribus denticulato, 

 supra convexo, punctato, postice fovea impresso ; elytris 

 oblongo-ovatis, crebre seriatim punctatis. 



Long. 1 lin. 



Mas. femoiibus incrassatis ; tibiis anticis, intermediisque ad 

 apicem intus sub-productis, extus oblique truncatis ; tarsi 

 antici articulo primo dilatato.

I possess specimens of this insect showing different shades of 

 colouring from testaceous to brown, pitchy brown, and black (in 

 the last the humerus is usually paler); but in the most common 

 condition, the head and thorax are black, or nearly so, and the 

 elytra rufous-brown, with the disc dusky. 



Not uncommon in the neighbourhood of London, but most 

 plentiful, according to my experience, near the sea, under decaying 

 vegetable matter. Common at Southend. 



Stephens has evidently taken his description of the present 

 species (and indeed all other species of Corticaria, excepting C. 

 pallida') from Gyilenhal, but in the diagnosis he has left out one 

 word referring to the sculpturing of the elytra, and by so doing 

 has omitted the very pith and marrow of the description. In the 

 original the elytra are described as " confertim punctato-striata," 

 and in the " Illustrations" the word " conferlim" is left out. This 

 is unfortunate, since it so happeps that C. crenulata, C. pubescens 

 (where the same omission has also been made) and C. serrata are 

 three species which, though differing- much in other respects, are 

 pre-eminently distinguished by this peculiarity in the sculpturing, 

 that instead of having about eight ordinary punctate stria?, they 

 have about double that number of closely-packed rows of punc- 

 tures, and the ordinary striae are not distinguishable. In speaking 

 of C. serrata these remarks should be slightly modified, for here 

 the punctuation of the true striae becomes rather more evident. 

 In other British species the punctures of the interstices of the
