1. T. hwmatocephalus, Schonh. Of this insect owly two supposed British speci- 

 mens appear to be known — one in Kirby's collection, which was received from ISIr. 

 Spence ; the other in the collection of Mr. Wollaston, to whom it was given, with 

 other small Coleoptera, as having been taken in the Isle of Wight. 



2. T. 5-punctatus, Linn. 



3. T. polylineahis. Germ., Schonh. This insect is also described by Schonherr, in 

 his ' Supplement' (vol. vii. p. 311), as T. lineatulus, Kirbij, from English specimens 

 sent by Mr. Walton ; but the somewhat obtuse tooth of the hinder femora is over- 

 looked, and I have no doubt that T. lineatulus and T. polylineatus will be found 

 identical. With regard to the name lineatulus, as applied to different species of 

 Tychius, there is evidently great confusion. The following abstract from my notes 

 I think will be found correct: — 



T. lineatulus of Schonh. (not of Kirby) = T. polylineatus, Germ., Schonh. 



T. lineatulus of Kirby's MSS. and collection :=T. Schneideri, Schonh. 



T. lineatulus of Stephens' ' Illustrations' = T. Schneideri (part) and Miccotro- 



gus picirostris (part). 

 T. lineatulus of Stephens' collection = T. polylineatus (part) and Miccotrogus 



picirostris (part). 

 T. lineatulus of Germar = T. uigrirostris of Walton's Catalogue, and perhaps 



also the T. tibialis, Schonh. 

 The T. polylineatus of Schonh., in our collections, is generally, if not always, 

 labelled " Schneideri," and is sometimes mixed with the true T. Schneideri. The 

 name lineatulus is given as synonymous with Schneideri both in W^alton's Catalogue 

 and that of Dr. Schanm. 



4. T. venuslus. Fab. 



5. T. Kirbii (T. flavicollis, var. /?., Schonh.; T. flavicollis, Walton, in the British 

 Museum Collection, not of Kirby or Stephens). Oblong-ovate, pitchy, densely 

 clothed with broad ochraceous scales, those on the under parts and on the suture of 

 the elytra whitish ; rostrum, antennae and legs testaceous ; thorax rounded and con- 

 tracted in front, the sides behind the middle line very nearly straight and parallel ; 

 elytra ample, with the humeral angles somewhat prominent, distinctly striated as seen 

 denuded of the scales, and of a rufous colour, excepting at the base ; rostrum long, 

 nearly straight and cylindrical ; posterior femora dentate in both sexes. Consider- 

 ably smaller than T. venustus, which it most nearly approaches in form, and distinctly 

 larger than either of the following species. 



The above species all have some at least of the femora dentate : the following 

 species have unarmed femora. 



6. T.junceus, Germ., Schonh. Oblong-ovate, pitchy (the elytra posteriorly more 

 or less red), densely clothedswith elongate yellowish scales; rostrum distinctly arched, 

 gradually attenuated from the base to the point of insertion of the antennae, then 

 rather more distinctly attenuated and somewhat pointed, especially in the males; an- 

 tennae, legs and the greater part of the rostrum testaceous ; thorax with the sides dis- 

 tinctly rounded ; elytra striato-punctate. General form shorter and more inclined to 

 ovate than the following species. Schonherr's description of T. flavicollis, as it 

 appears to me, belongs almost entirely to this species. 



7. T. tomentosus. Germ., Schonh. Oblong, pitchy black (the apex of the elytra 

 more or less rufescenl), above clothed pretty densely with elongate pale yellowish 

 scales, with filiform scales on the striae of the elytra, and a few broad while scales on
