198 Mr. J. S. Baly on neio species of Phytophagous Beetles. 



Dolichotoma speciosa. PI. V. fig. 6. 



D. rotundata, leniter convexa, nigro-senea ; elytris plaga magna intra- 

 marginali sanguiiiea, nigro-senea notata instructis. — Long. 7\ lin. 



Rotundate, moderately convex, dark nigro-seneous, subopake ; 

 each elytron with a large sanguineous submarginal vitta, which 

 extends from below the base nearly to the apex, its surface 

 dotted here and there with roundish nigro-seneous spots. Head 

 impressed on the vertex with a large fovea ; antennae nearly the 

 length of the body, black, six basal joints rufo-piceous beneath. 

 Thorax short, transverse, concave-emarginate at the apex; sides 

 rounded and dilated, reflexed ; above convex in the middle, con- 

 cave on the sides, central line transversely impressed just in 

 front of the basal lobe, surface indistinctly punctured. Elytra 

 much broader than the thorax ; shoulders rounded, sides regu- 

 larly rounded and dilated to their middle, narrowed and sub- 

 sinuate below the latter, thence to their apex regularly rounded, 

 apex obtuse ; above moderately convex, obsoletely gibbous below 

 the scutellum ; surface covered with large deep punctures, which 

 are smaller and less deeply impressed close to the apex ; margin 

 dilated, slightly deflexed, its outer edge somewhat reflexed; 

 smooth, and almost entirely covered by a large submarginal 

 sanguineous patch, over the surface of which are scattered some 

 shallow subrotundate nigro-seneous spots. Beneath dark shining 

 nigro-seneous ; under surface of four anterior thighs rufous.

Calaspidea Bohemani. 



C. rotuudato-ovata, valde convexa, obscure viridi-senea, subopaca ; 

 elytris intra marginem laxe sanguineo-reticulatis. — Long. 9^ lin. 



Rotundate-ovate, subopake, obscure metallic green, the outer 

 border of the elytra sparingly covered with some irregular 

 sanguineous reticulations. Head smooth ; antennse more robust 

 than in C. discors, third joint rather longer than the fourth. 

 Thorax transverse, apex concave-emarginate; sides dilated, re- 

 flexed, regularly rounded ; above convex in the middle, indi- 

 stinctly depressed transversely in front of the basal lobe, sides 

 deeply concave and covered with irregular shallow depressions ; 

 surface shining metallic green, indistinctly punctured. Elytra 

 much broader than the thorax, very convex, shoulders slightly 

 prominent, retuse, humeral angle obtuse; sides dilated and 

 rounded to their middle, thence narrowed and rounded to the 

 apex, tbe latter rounded ; disk covered with shining, distinctly 

 punctured, slightly elevated reticulations, which enclose small 

 opake areoles ; lateral margin dilated, deflexed, subopake, finely 

 punctured, covered within the outer border with irregular loose
