Ann. 1867, p. 126). The true P. ccesum appears to be 

 distinguishable by its wide form, large head, and the con- 

 vergence towards the front of the lateral lines of its thorax. 

 From its ally P. ajffiiie, it may be known also by its much 

 smaller size, its more cordate thorax, and the finer, closer, 

 and more regularly asperate-punctuation of its elytra.

 Mag., ix, p. 179, described (1 January, 1873). 



Allied to T. picicorfiis, Mann., but with paler and more 

 slender antennas, of which the 8th joint is linear and not 

 incrassate, and in the punctuation of the thorax and elytra, 

 the former being covered with minute but distinct tubercles 

 arranged in wavy rows, with the interstices reticulate and 

 shining, and the latter being deeply and very closely aspe- 

 rate. 



A single example was taken in August, 1868, in Thoresby 

 Park, Nottinghamshire, by the Rev. A. Matthews, in whose 

 collection it still remains unique.

 Further localities (Loughton, Caterham and Esher\ sexual 

 characters, and variations in size, have been recorded for 

 the insect dubiously brought forward by myself under this 

 name ; and, the discrepancies between the original British 

 specimens and FaiiTuaire's description of A. grandis (the 

 main one being that the thorax cannot possibly be said to be 

 not contracted behind, but is, compared with A, cinnamomea, 

 distinctly less contracted in front) being, if anything, in- 

 creased by the additional individuals examined, I have 

 provisionally attached the name anglica to our species, in 

 case it should turn out to be distinct from that characterized
