EROTYLlDyE. 107 



larger size, raore convex and rounded sliape, and stronger punctviation. 

 The colour is very variable. The species is probably, as Mr. Donis- 

 thorpe points out, one of the ground feeders, which prey upon the 

 aphides at the roots of sea-lavender, and other salt marsh plants. 



P. lividus. Bold. This species must be deleted, as it is only a 

 small pale example of P. testaceus, Mots. {v. Newbery, Ent. Mo. Mag 

 xli. (2 Ser. xvi.), 1905, 161). 



P. mulsanti, Wat., has apparently proved such a puzzle to foreign 

 coleopterists that it is omitted altogether from the last European 

 Catalogue ; it may be synonymous with, or a variety of P. testaceus, Mots. 



ENDOMYCHIDiE. 



The table for the Mycetceina must be altered (Brit. Col. iii. 179), 

 as the antennas of Symhiotes, Redt., are 11-jointed and not 10-jointed. 



I. Antennas 11-jointed. 



i. Thorax with a strong impressed line on 



each side extending from base to beyond 



middle Syjibiotes, Redt, 



ii. Thorax with impressed line extending 



from base to apex Mycet^a, Ste2yh. 



II. Antennas 10-jointed • . . . . Alexia, Steph. 



EROTYLIDiE. 



DACNE, Latreille. 

 (D. fowleri, Joy (Ent. Mo. Mag. xli. (2 Ser. xvi.), 1905, 274). Dr. 

 Joy describes this species on specimens found in a hole in a large oak log 

 at Bradfield, Berks ; he believed them to be distinct from D. kumeralis 

 on the ground that the reflexed margins of the thorax were much 

 broader than in the last-mentioned species and almost explanate in 

 front, the anterior angles being more prominent ; the insects, moreover'^ 

 appeared to be much more active than D. Jmmeralis. From the first 

 I was doubtful of the species, and Dr. Joy is now of opinion that it 

 cannot be retained ; it is, at most, a variety or sub-species.) 



TRIPLAX, Paykull. 

 T. (Platychna) bicolor, Gyll., Ins. Suec. vol. i. p. 205 (1808); 

 T. scutellaris, Chai^p., Horas Ent. 1825, 244 {teste Ganglbauer). 

 Usually of about the same size as T. russlca, L. ; the British examples, 

 however, which have been hitherto taken, are on the average decidedly 

 smaller, and intermediate between that species and T. amea, Schall. ; 

 easily distinguished from T. 7'ussica, which it most nearly resembles, 

 by having the base of the thorax very finely and scarcely visibly 

 bordered and never provided with a transverse furrow (subg. Platychna, 

 Thoms.), by its more ovate shape, the sides of the elytra being 

 distinctly more rounded, and by the reddish or reddish-yellow colour of
