mate joint lobed and wider than the preceding joint, the claws appendiculate ; 

 ventral segments 1 and 2 sub-equal in length along the median line, 2 with a 

 pubescent pad in S • 



Type : L. cliilensis. 



Three S. American species are referred to Larcoderus. These 

 insects are closely related to the imperfectly known '^. American genus 

 Lacconnhis Lee.,* differing from it {L. pinicola) in the stouter maxillary 

 palpi, large eyes, deeply bifoveate disc of the prothorax, etc. Compared 

 with Euryjrus, the tarsi ai-e narrower, and have a much less dilated 

 penultimate joint, and the antennae are not so strongly serrate. The 

 (J of L. chilensi!^ has a large pad on the second ventral segment, much 

 as in the same sex of the Palaearctic 3Iycterus curctdionoides ¥., the 

 corresponding pad in Lacconotus pinicola ^ , being oblong, instead of 

 transverse. According to both Leconte and Hoi'n the first ventral 

 segment in Lacconotus is shorter than the second, but this is not the 

 case with L. pinicola. 



1. — Laccoderus chilensis, n. sp. 



Elongate, depressed, sub-parallel ( <? ), widened posteriorly ( $ ), shining ; 

 piceous or fuscous, the head and a space down the middle of the prothorax 

 usually reddish or rufo-testaceous ; the elytra testaceous, with the sides, an 

 oblique streak or angulate fascia extending thence to near the suture at 

 about the middle, and an oblong mark along the suture before the apex, 

 piceous or fuscous, the dark markings sometimes so extended as to leave only 

 an oblong spot on the anterior part of the disc and an oblique sub-apical fascia 

 testaceous ; the antennae towards the tip, and the femora, usually testaceous 

 or reddish ; densely, finely punctate and somewhat thickly pubescent. Head 

 broad, sulcate down the middle ; eyes large, convex, separated by about their 

 own width ; antennae reaching to a little beyond the humeri, joint 3 longer 

 than 2 or 4, the latter sub-equal in length, 4-10 sub-triangular, about as long 

 as broad, 11 aciuninate-ovate. Prothorax transverse, narrower than the head, 

 slightly narrowed in front, feebly sinuate at the sides before the sub-acute 

 hind angles, the base bisinuate and conspictiously margined, the two dorsal 

 foveae large. Elytra long, rounded at the tip, obsoletely grooved, the punctures 

 equal in size, the suture depressed before the apex. Ventral segment 2 with 

 a rather large, oval, transverse, densely pubescent, raised pad in the middle, 

 and 5 broad and transversely grooved towards the apex, in <J . Length 4f-6i, 

 breadth If-^^ mm. 



Hab.: Chile {Reed), Valdivia (ex coll. Bates). 



Nine specimens, including four males, varying greatly in the 

 development of the elytral markings, according to the predominance 



* I am greatly indebted to Mr. H. P. Wickham for a (J of the rare L. piaicola Horn, for 

 comparison. L. 'pimctatus Lee, the type of the genus, is unknown to me.
