198 CURCULIONID^. 



PHYTOBIUS, Schmidt. 



P. muricatus, Ch. Bris. (Gren. Cat. Col. de France, p. 1S7). 

 Mr. Champion (Ent. Mo. Mag. xxxv. (2 Ser. x.) l«9i), 143) says that 

 this is probably the insect doing duty in our British collections for 

 P. quadrinodosus, (!yll., whereas the name quadrinodosus should be 

 applied to the species known to us as P. denticollis, Gyll. The latter 

 has been included under PJdnoncns by Bedel, myself, and others, but 

 wrongly, as it has the funiculus of the antennse (5- (not 7-) jointed. 

 P. muricatus has the elytra much broader than in P. quadrinodosus, 

 the thorax with the sides more oblique, the elytra much broader in 

 proportion to the thorax, with the shoulders much more prominent 

 and the third to the ninth interstices muricate ; in ]\ quadrinodosus 

 the shoulders are rounded oft', and the base of the elytra is almost as 

 broad as the base of the thorax, and the fifth to the seventh interstices 

 only are muricate. 



The synonymy of the two species will therefore stand as follows, 

 both being included under the genus Phytohius : 



P. virtricatus, Ch. Bris. (IST)?). 



granatus, Thorns. (LSdo) {nee Gyll. 1836). 



quadrinodosus, Shai-p and Fowler. 

 P. quadrinodosus, Gyll. (1813). 



denticollis, Gyll. (1837). 



LIMNOBARIS, Bedel. 



Ij. pilistriata, Steph. (111. Brit. iv. p. 10). Mr. Champion 

 points out (Ent. Mo. Mag. xH. (2 Ser. xvi.) 1905, 224) that J. Sahlberg 

 (Acta. Soc. pro Fauna et Flora Fennica xix. 3, pp. 22, 23 (1 900)) separates 

 Paris T.-alhum into two species, B. T.-album, L., and i>. martidus, 

 Sahib. The P. T.-alhitm of Sahlberg appears to be the B. pili- 

 striata of Stephens, and, as the Linn;ean description applies better 

 to B. T.-album than to B. jnlistriafa, Stephens's name must stand, 

 if the two forms are to be regarded as separate. I feel coMsider- 

 able doubt as to their distinctness, as Stephens himself (Manual, 

 p. 21(')) subsequently treated his insect as a "fine form" of 

 B. T.-albitm. 



The following synonymy and distinctive characters are given by 

 Champion [l.c) : 



I. Larger and more elongate, the elytral 

 interstices irregularly uniseriate- 

 punctate, especially towards the 

 suture, the punctures each bearing 

 a rather long, coarse, decumbent, 

 whitish hair . . . . B. pilistriata, StejjJi.
