144 Mr. G. R. Waterhouse's Revision of the 



extremely minute punctures, arranged in a line, in which same 

 line is a series of ir.inute pale hairs. 



In the structure of the legs I can perceive no sexual distinc- 

 tion, such as exists in C gibbosa, but it must be remarked that I 

 have examined but six specimens of the supposed new species ; 

 these were found by Mr. Wollaston, at Mablethorpe. 



The British Museum has received this insect from the Conti- 

 nent, under the name of C. dislinguenda of Comolli, but according 

 to the description of that insect, its thorax must be shorter, i. e. 

 half as broad again as long. The C. shnilala must somewhat 

 resemble the present species, but differs, according to the de- 

 scriptions, in having the interstices of the striae of the elytra 

 rugulose. I can find no description of a Corticaria which is like 

 C gibbosa in most of its characters, but which differs in the same 

 manner as the present insect. 



11. Corlicaria fuscula. C. breviter ovata, fusco-picea, thorace 

 transverse, angulis posticis denticulo minuto arraatis, supra 

 crebre punctato, fovea sub-rotundata impresso ; elytris 

 fuscis, punctato-striatis, interstitiis convexiusculis, seriatim 

 pilosis; antennaraum basi, pedibusque testaceis.

Very like C. gibbosa, but readily distinguished by the form of 

 the thorax, which is broad (about one-third broader than the 

 head), transverse, has the sides boldly rounded, the widest part a 

 little in front of the middle, the posterior angle armed with a minute 

 tooth and thus rendered acute and prominent; this tooth, however, 

 is not readily seen, excepting the thorax be separated from the 

 body ; instead of the curved groove, which in C. gibbosa extends 

 nearly from side to side of the thorax, C. fuscula has only a fovea 

 behind, and this is commonly transverse. The elytra scarcely 

 differ from those of C. gibbosa — the striae are perhaps usually 

 rather stronger, and ihe intersticial punctures less so. In the 

 most common condition the head and thorax are pitchy, or pitchy- 

 brown, and the elytra brown, with the suture rather dusky ; but, 

 not unfrequently, the whole insect is brown ; and, about the be- 

 ginning of September this year, I found many specimens at South- 

 end, which were entirely testaceous — no doubt from immaturity. 

 In both the above-mentioned species minute transverse rugulse
