162 DOLERUS LATERITIUS. 



behind the eyes, the sheath before the apex emarginate 

 slightly and without a tooth, and the <$ has white on 

 the fourth to the sixth abdominal segments. Yon Stein, 

 however (Ent. Nacht., 1887, p. 170), sinks trigeminus 

 as a variety of palmatus, Kl., and in this view Konow 

 himself (D. E. Z., 1890, p. 251) agrees. 



DOLERUS TRIPLIOATUS (Vol. I, p. 162). 



The c? of this species is D. tremulus, Kl. (Berl. 

 Mag., viii, 228), and Konow and von Stein propose to 

 use this as the specific name ; but inasmuch as S-pli- 

 catus was printed before tremulus I prefer to retain 

 this designation. 



The cf I have described differs from tremulus in 

 having the thorax coloured like the ? , i. e. yellow 

 with three black marks, and the base of the abdomen 

 is not black. 



"Whether the <? I have described is a variety of the 

 $ of triplicatus, or if it belongs to a new species, is a 

 point which I cannot make out from the material at 

 my command, but I can find nothing like it described. 



DOLERUS LATERITIUS (Vol. I, p. 163). 



Konow adopts the name of madidus for this species 

 (D. E. Z., 1890, p. 251, and 1886, p. 79) ; lateritius, 

 KL, ? , being a composite form according to him, 

 having madidus as <$ for one part, and uliginosus, Kl., 

 for the other. In the ? the polished space on the 

 eighth abdominal segment occupies at least one half the 

 length of the segment, while in uliginosus it is short 

 and broadly triangular, and does not occupy more 

 than one-third of it. D. Lamprechti, Knw. (D. E. Z., 

 1879, p. 341), is a synonym. 



The larva as described by Brischke (I.e., 45, Taf. ii, 

 fig. 7) feeds on Juneus glomeratus. It is 25 mm. long, 

 bright greenish-yellow on the ground colour, the back
