510 ENTOMOLOGICAL NOTES 



Cyl. pallida. Testacea, oculis fuscis. 



The head, antennae, prothorax, elytra, and legs, are entirely of a 

 pale brown colour ; the eyes alone are darker : the prothorax and 

 elytra are slightly rugose ; the former has an indented ring near 

 the anterior, and another near the posterior, margin. (Length 

 4 lin.) 



Mr. Bently's rich cabinet contains a specimen of this insect. 

 Mr. Ingpen has taken it more than once, and I possess one 

 which was taken at Camberwell. I have reason to believe 

 that it is not an uncommon insect, but, from a similarity of 

 colour, has been taken for Callidium variahile, a species to 

 which widely differing insects appear to have been frequently 

 referred. 



Genus. — Tritomacrus.'' Newman. 



Caput prothorace paullo angustius : mandibulis elongatis, porrectis, 

 vix dentatis, apice arcuatis : oculi prominentes : antennis corpora 

 valde longioribus, articulo 1°. incrassato, 2". brevissimo, 3°. lon- 

 gissimo, caeteris longitudine decrescentibus, et ad apicem pede- 

 tentim attenuantibus : prothorax elongatus, depressus, indentatus, 

 lateribus convexis : elytra postice paullo angustiora ; femora prse- 

 cedente minus incrassata. Characteribus aliis vix Obrione difiert. 



Trito. testaceus. Testaceus, oculis fere concoloribiis, an- 

 tennis corpore valde longioribus. 



Testaceous, the eyes being nearly of the same colour : the antennae 

 are much longer than the body, pubescent, and taper gradually 

 to a point. (Length 5 lin.; antenno3 8 lin.) 



The only specimen I have seen of Trilomacrus testaceus 

 is in Mr. Bently's cabinet, and named Obrium pallidum ; it 

 was taken by Mr. Whitecroft, in Ireland. I should have 

 been very glad to have retained the specific name, but thought 

 it more applicable to the preceding species, and did not like 

 to give them both the same name. From the descriptions, I 

 think it will be seen, that Tritomacrus is more nearly allied 

 to Obrium, Cylindera to Callidium, forming, together with 

 those genera, a beautifully connected series. 



« T^iTos tertius, fxanpos longus : — third joint long; in all the Cerambicites this 

 is partially the case, but in the present instance very remarkably so.
