JDescriptiont of four new British species of HalticiJce. — I see by the (Piener ent. 

 Monalsvhrift,\o\. 8 (1864), that among the Britiali species of Halticidic forwarded by 

 my father to Herr Kutscbera for inspection, are four species new to science. One of 

 these is the " Psylliodes, spe. 6," of my father's catalogue, a species discovered by Mr. 

 WoUaston in Lundy Island, and which is pretty well known to English Coleopterists. 

 To this Herr Kutschera gives the nama P. Itiridipennis (p. 393 of the Monatschrift). 

 The other three species belong to the genus Thyamis (Longitarsus), and are named 

 L. fusculus, L. Waterhousei, and L. gracilis. They are characterized as follows 

 {Monatschrift, pp. 273-5) : — 



1. Thyamis {Longitarsus) fusculus, Kutsch. " Oblongo-ovatus, sub- convexus, 

 nitidus ; fuscus aut fusco-piceus, elytrorum humeris, margine apiceque, antenuarum 

 basi et pedibus pallidioribus : thorace transverao, tenuissime granuloso et minutissime 

 punctulato ; elytris humeris vix prominulis, apice singulatim obtuse rotnndatis 

 distincte dense ac confuse ruguloso-punctulatis. Apterus — Long. | — 5"'." 



S . Abdominis segmentum ultimum foveola rotundata et profunda ornatum et 

 leviter 2-sinuatum. — Tarsorum anteriorum articulus 1. modice diktat us." 



Differs from T. brunnevs and minusculus in being less convex, and more thickly 

 punctured in the elytra. 



2. T. Waterhousei, Kutsch. " Ovatus, conyexus, nitidus ; capite ferrugineo, 

 vertice obscuriore, labro nigro-piceo ; thorace rufo-ferrugiueo, elytris, antennarum 

 basi pedibusque testaceis ; abdomine nigro, segmento ultimo pygidioque ferrugiueis ; 

 fronte encarpis distinctis ; thorace transverso ruguloso-puuctulato ; elytris ovatis, 

 humeris prominulis, apice vix conjunctim rotundatis, fortius confuse seriatimve punc- 

 tatis. Tibiarum posticarum spinula apicali longa. Apterus — Long. 1'"." 



This species is compared with T. hallotce and lycopi ; and distinguished from the 

 former by its more glossy surface and reddish colouring ; and from l<jCopi by its larger 

 size, greater convexity and breadth, and by its coarser, and, on the elytra, very indis- 

 tinctly striate punctuation. 



3. T. gracilis, Kutsch. " Oblongo-ovatus, depressiusculus, nitidus ; albido- 

 testaceus, capite pectore abdomineque pallide ferrugineis ; ore piceo ; antennis 

 extrorsum et tarsorum articulis ultimis cum unguiculis fuscescentibus : fronte encarpis 

 subdistinctis ; thorace transverso latiusculo laevi aut vix punctulato ; elytris ovatis 

 pellucidis, humeris modice prominulis, apice subsingulatim rotundatis, minutissime et 

 obsolete confuse punctulatis. Tibiarum posticarum spinula apicali brevi. Alatus — 

 Long: 1-^'"." 



" <J . Abdominis segmentum ultimum linea longitudinal! tenui ornatum, apice 

 bisinuatum." 



Extremely like a small T. ochroleucus, in which the blackish colouring of the 

 apical half of the hind tibise is wanting. The tliorax is broader than in ochroleucus, 

 more than half broader than long, at the sides gently rounded, and with a gentle 

 projection behind the anterior angles. The insect is common at Mickleham, and 

 elsewhere, on Senicio Jacobcea. 



4: Psylliodes luridipennis, Kutsch. Oblong-ovate, of the size and build of P. 

 hyoscyami, but not so broad ; head and thorax brassy green. Elytra reddish-brown, 

 shining, with brassy green legs, and testaceous autcnnse ; the hind femora brassy, pale 

 at the base. Its smaller size, brassy colouring, and more finely and closely pumtatc- 

 striato elytra will serve to distinguish it fi'om P. chrysucephala.
