86 TRAVELS AMONGST THE GREAT ANDES. 



two following, united ; claws appeudiculate ; posterior femora very moder- 

 ately thickened. 



The strongly and regularly punctate-striate elytra distinguish this species 

 principally from other South American forms ; I am somewhat doubtful if 

 the true place of the present insect is in Aphthona. 



15. Diholia viridis, n. sp. 



Hab. Eastern side of Corazon (12,000 feet). Three examples. 



Ovate, testaceous ; terminal joints of the antennae, hlack ; above light 

 green, thorax transverse, remotely punctured ; elytra closely and strongly 

 semistriate-punctate, the interstices .slightly rugose. 



Length, 3| mm. 



Head obscure testaceous, impunctate, transversely grooved between the 

 eyes ; frontal tubercles oblique, distinct ; clx-^Jeus swollen, triangular ; 

 antennae less than half the length of the body, tlie second and third joints 

 equal, short, fourth slightly longer, the rest gradually ^\■idened ; basal and 

 third joint testaceous, the second and terminal joints black ; thorax nearly 

 three times as broad as long, narrowed in front, the sides nearly straight, 

 posterior margin rather strongly rounded ; anterior angles obtuse and 

 thickened ; surface distinctly but very remotely punctured at the disk, more 

 closely at the sides with an obsolete fovea near the posterior angles ; scutel- 

 lum obscure testaceous ; elytra narrowed towards the apex, not wider at the 

 base than the thorax, vnth a longitudinal depression within the humeral 

 callus ; surface very closely and rather strongly punctured, the punctuation 

 arranged in irregular rows near the suture, the interstices, especially at the sides, 

 .slightly transversely wrinkled, the space near the lateral margin, impunctate ; 

 legs robust, posterior femora strongly incrassate, their tibiae deeply channelled 

 and dilated at the apex, the latter armed with a distinct bidentate spur ; 

 first posterior tarsal joint scarcely as long as the two following united ; claws 

 appendiculate ; prosternum broad, pubescent. For Figure see the Plate 

 facing p. 84. 



The species described here, which may be known at once by its pale 

 green colour, seems to be the first of the genus which has l)een obtained in 

 South America. 



1 6. Diphaulaca glahrata, n. sp. 



Hah. Eastern side of Picliincha (12-13,000 feet). Two examples. 



Oblong-ovate, black below ; above metallic green ; first three joints of 

 the antennae obscure fulvous ; thorax impunctate ; elytra extremely finely 

 punctureil. 



Length, 3-4| laiii.
