This species in outward appearance so closely resembles Arthrolips ohscurus that 

 it is almost impossible to distinguish them from each other except by the antenna'. 

 They differ, however, comparatively in the following characters: in S. corticininn 

 the "thorax is smaller and more deeply punctured, and the elytra much attenuated 

 posteriorly, with the apex almost entire; in A. obscurus the thorax is larger, 

 broader, and more finely and more closely punctured, and the elytra are not 

 attenuated, but broad and much rounded at the extremities. 



Sacium brunneum. 



S. brunneum, Brisout de Barneville, Cat. Gren. p. 70, 1863. 



L. c. ^1 lin. = 1'63 mm. — Ovale, valde convesum, sat nitidum, sat profunde 

 punctatum, fusco-castaneum, pilis flavesceutibus vestitum ; pronoto sat parvo, 

 antice ovaliter rotundato, modice reflexo, et pellucido, modice et sat remote 

 punctato, interstitiis glabris, nitidis, margine basali sinuata, angulis rectis ; df/tris 

 pronoto parum latioribus, plus quam duplo longioribus, atque magis profunde 

 punctatis, ad media latissimis, interstitiis glabris, nitidis, stria suturali indistincta, 

 lateribus marginatis, apicibus valde rotundatis ; abdomine segmentis duobus 

 expositis ; pedibus sat longis, flavis ; antennis brevibus, flavis. 



Body oval, very convex, moderately shining, rather deeply punctured, fusco- 



castaneous clothed with flavescent hair. 

 Head moderate ; eyes rather large, dusky ; antenuse very short and robust, 



flavescent, with the seventh joint slightl_y enlarged. 

 Thorax small, ovally rounded, moderately reflexed and pellucid in front, moderately 



and rather distantly punctured with the interstices smooth and shining, 



basal margin sinuated, with the angles right angles. 

 Scutellum moderate, rounded. 

 Elytra rather broader, more than twice longer, and more deeply punctured than 



the thorax, widest at the middle, interstices smooth and shining, sutural stria 



indistinct, sides faintly margined, extremities very much rounded. 

 Abdomen with two segments exposed, flavescent. 

 Legs yellow, long and slender. 

 Under parts flavescent. 

 Differs from S. corticinum in its much smaller size, narrower form, and much 



shorter antennae. Immature specimens of jS'. latam are often mistaken for this 



species, but may be recognized by their larger thorax, broad-shauldered 



elytra, and longer antennae. 

 Habitat, Europe. Found in France and other countries. 



Sacium elongatum, sp. n. 



L. c. if-|i lin. = 1-63-1-75 mm.— Valde elongatum, fere lineare, modice 

 convexum, rnodice et regulariter punctatum, pilis aureis vestitum, rufo-castaneum, 

 pronoto rufescenti ; pronoto parvo, angusto, antice ovaliter rotundato et late reflexo, 

 modice et regulariter punctato, interstitiis glabris, nitidis, linea basali sat profunda, 

 margine basali vix sinuata, angulis rectis ; eli/iris prselongis, angustis, pronoto plus 

 quam duplo longioribus, vix latioribus, ante media latissimis, castaneis, humeris 

 atque apicibus rufescentibus, modice et regulariter punctatis, interstitiis glabris, 

 nitidis, stria suturali profunda, lateribus marginatis, apicibus vix rotundatis ; 

 abdomine rufescenti, segmentis tribus expositis ; pedibus longis, gracilibus, Isete 

 flavis ; antennis flavescentibus, articulo septimo valde incrassato.
