and Species of Eumolpida. 887 



This insect, by its cylindrical form and the smaller size of its 

 spots, approaches M. humeralis and M. tetrasticta ; and the 

 three, with M. testacea, Fab., and others, form a group of allied 

 species.

Metaxyonycha quadrinotata, sp. ined. 

 M. testacea, antennarum articulis 4-12, nigris ; thorace elytris angus- 

 tiore, lateribus medio bisinuatis ; elytris confertim, prope suturam 

 seriatim punctatis, apicem versus costatis, costis laevibus ; in singulo 

 elytro maculse duse magnse fusco-cserulese ; antennse crassiusculse ; 

 tarsi subinfuscati. 

 Long. lin. 4^-5, lat. hum. l|-2 lin. 



Closely allied to M. crucifera (of which it may be a permanent 

 local variety), but separated (1) by the thick antennse, (2) by the 

 punctuation of the elytra, (3) by the brownish-blue tint of the 

 dorsal blotches. Head and thorax smooth, shining, with scat- 

 tered punctures. A single punctured stria next the suture, 

 followed, after a wide smooth interval, by a line of doubled 

 punctures ; the rest of the elytra hardly striato-punctate, except 

 at the apex, where the usual eight smooth costse become visible, 

 their interstices punctured. Otherwise like M. crucifera. 

 Hah. Brazil. From Thomson^s collection. 



Metaxyonycha humeralis, sp. ined. 

 M. oblongo-ovata, subcylindrica, nitida, scite punctulata, testacea, 

 oculis nigris ; elytris punctato-striatis, cujusque striae punctis ge- 

 minatis, interstitiis laevibus, postice elevatis. Elytron utrumque 

 maculis binis, parvis, rotimdis, nigro-cseruleis, quarum altera major 

 in ipso callo humerali sita, altera infra medium minima. 

 Long. lin. 4, lat. hum. 1^ lin. 



Front with three small fovese, arranged in an arc above the 

 antennse and between the eyes. Thorax finely margined at the 

 sides and base, with a scarcely visible sinus in the middle of 

 each side; like the head, irregularly punctured and shining. 

 Scutellum impunctate, shining, and, with the head and thorax, 

 pale reddish testaceous. Elytra paler, broader at the base than 

 the thorax, parallel for three-fourths of their length, thence 

 to the apex conjointly attenuated and rounded, and in an equal 

 degree deflexed from above : punctate-striate, the punctures 

 geminated, the interstices shining, elevated posteriorly into four 

 smooth costse next the suture, and, after a wider interval, three 

 more, of which the first is continued from the base to the apex, 

 and connects the two cyaneous spots on their outer edges. On 

 the humeral callus is a round cyaneous spot, angulated poste- 

 riorly, and behind the middle a much smaller discal dot.
