36 M. mutator. Niger, pube cinereo variegatus, thorace confertim rugoso-puncta- 

 to, spinis horizontalibus dense albido-pubescentibus, scutello albo, elytris dense punc- 

 tatis, punctis antice elevatis ; rufo-piceis, pube cinereo, fuscoque variegatis, antennis 

 nigris, cinereo annulatis. Long. -98. 



This is very similar to M. confusor Kb. (maculosus Hd.), but the thorax, which is 

 smooth in that species with a few small punctures, is rugosely punctured, and the 

 suture of the elytra is slightly prolonged. The $ has very long black antennae. 



37 ARGALEUS. Caput mox pone oculos non constrictum ore attenuate, palpis labi- 

 alibus modice dilatatis. Antennae ante oculos insertae, longac ; oculi antice emarginati, 

 postice truncati. Tibiae posticae apice truncates, calcaribus terminaliter sitis. Thorax 

 spinosus. Elytra triangularia. 



Differs from Toxotus cylindricollis, &c., in the form of the eyes, as well as the situa- 

 tion of the terminal spurs of the tibiae. The spinous thorax gives an appearance like 

 Rhagium. To this genus belongs the European Toxotus cursor. 



A. nitens. Minus elongatus, niger subtiliter dense punctatus longe cinereo-pubes- 

 cens, thorace canaliculato, antice angustato, basi apiceque profunde constricto, lateri- 

 bus acute tuberculatis, elytris postice angustatis, apice subtruncata, glabris punctatis 

 luteis, disco saepius infuscato ; antennis articulo 4 to abbreviato. Long. -6. Pic. 



39 Evonixus. Caput mox pone oculos angustatum, ore attenuato ; palpis apice 

 oblique truncatis. Antennae ante oculos insertae, longae : oculi magni vix emarginati. 

 Thorax lateribus acute tuberculatus. Mesosternum angustum, parallelum, coxis mag- 

 nis. Elytra triangularia, apice truncata. 



E. monticola. Niger, fulvo-pubescens, thorace canaliculato, utrinque constricto, 

 elytris subtilissime rugose punctatis, flavis, utrinque maculis 2 parvis ante medium 

 transversim sitis, alteris 2 majoribus lateralibus, apiceque nigris : antennis rufescenti- 

 bus, corpore vix brevioribus. Long. -4. On the flowers of Cornus. 



40 ACM.EOPS. Caput mox pone oculos angustatum, palpis apice recte truncatis. 

 Antennae ante oculos insertas. Thorax apice constrictus, vel tuberculatus, vel gibbus, 

 vel simplex. Mesosternum triangulare. 



A numerous group, which may be dipped into two sections. 



A. Body thick, mouth short. Pachyta thoracica Hd. some new species, with the 

 European P. virginea and collaris. 



B. Body more slender, mouth elongated : the species cited above, with 4-vittata. 



41 A. strigilata. Niger, punctatus, flavo-pubescens, capite elongato, subrostrato, tho- 

 race convexo antice angustato, tenuiter canaliculato, minus dense punctato, elytris 

 latiusculis, postice non angustatis, apice truncata, luteis humeris apiceque infuscatis. 

 Long. -28.
