322 Mr. G. R. Waterhouse's Descriptions 



Sp. 17. Pachyrhynchus concinnus, Waterh. 



Ater ; elytris punctato-striatis ; thorace in medio lined trans- 

 versa, et pone banc linea longitudinali ; elytris lined transversd 

 centrali, lineis duabus longitudinalibus et linea marginali ; 

 his lineis pallide viridibus. 



Long. Corp. G — 7 lin. 



This species closely resembles the P. chlorolineatus, but differs 

 in being larger, in having the markings broader than in that 

 insect, and the rows of punctures on the elytra more distinct. 

 The longitudinal marks on the elytra are often interrupted near 

 the transverse mark. 



Sp. 18. Pachyrhynchus multipunctatus, Waterh. 



Ater ; capite maculis tribus, earum una interoculari, una 

 utrinque suboculari ; thorace nitido, dorso binotato, ad latera 

 lineis duabus ; elytris punctis plurimis ornatis ; his lineis 

 punctisque viridibus. 



This species is equal in size to the P. mon'iUferus, but its form 

 is more elongated. Scarcely a trace of any punctures is observ- 

 able on the head and thorax. On tlie elytra are rows of very 

 minute punctures. 



Sp. 19. Pachyrhynchus reticulatus, Waterh. 



Niger; capite lineis tribus longitudinalibus notato ; thorace 

 elytrisque lineis aureo-viridibus vel cupreis areas polygonas 

 circumdantibus reticulate ornatis. 



The P. reticulatus is equal in size to P. montUferus ; its rostrum 

 is narrower, and the thorax is rather shorter, and the elytra less 

 globose. A tolerably broad groove is observable between the 

 eyes, which runs down on to the rostrum, where it terminates, 

 having become gradually broader, in a transverse line at the point 

 of insertion of the antennae : the fore part of the rostrum is 

 thickly and finely punctured. The thorax is impunctate. The 

 elytra are provided with rows of small but distinct punctures. 

 The markings are all in the form of narrow lines, of brilliant, 

 golden, green, or reddish gold scales. On the head is a longi- 

 tudinal line above, and another on each side beneath the eye. The 

 upper surface of the thorax is divided into five areas by coloured 

 lines, — two areas in front, which are more or less confluent, two 

 behind, and a small central one ; and on each side of the thorax 

 there is moreover a large inclosed area. The elytra have the
