starts from the middle of the fascia, which is there angulated towards 

 the apex. The abdomen is not punctured as in P. curvipes, on 

 each side. The front tibise in the male are more suddenly dilated 

 below the middle, and their inner sides above the middle are distinctly 

 crenulated. Three specimens. 



24. Megischyrus elongatxjs. 



Saturate sanguineus, parum nitidus ; prothorax subopacus limbo 

 laterali nigro ; elytris postice gradatim attenuatis, callo humerali, 

 maculis duabus obliquis {interiore majore in medio constricto) 

 dimidioque apicali nigris. 



Long. 15-17 millim. 



Var. Supra totus saturate rufus, elytris callo humerali maculisque 

 duabus obliquis tantutn nigris. 



Long. 17 millim. 



Hab. Peru, Chancomayo. 



A verj' distinct species, to be recognized by its very narrow 

 elongate form. It is widest at the shoulders, the thorax narrowing 

 in front with nearly straight sides, and the elytra gradually tapering 

 behind. The colour appears variable : in the three specimens before 

 me two have the apical half of the elytra black. In one of these the 

 head and body beneath is almost black, while the thorax is very 

 obscurely red, yet with black lateral margins. In the other the 

 head and thorax are more decidedly red ; while in the third example 

 the colour above is light brown, with only the three elytral spots and 

 the lateral margin narrowly black. The tibise and extreme tips of 

 the femora are black in all of these three specimens. 



It should be placed near M. bellicosus, 



25. Megischyrus bartletti. (Plate XVIII. fig. 9.) 



Niger, subnitidus ; elytris striatis, striis obsolete punctatis, fasciis 

 quatuor maculis alternis distinctis Uneaque submarginali flavis. 



Long. 17 millim, 



Hab. Peru, Chamicuros (^Bartlett). 



Elongate, sides of the elytra rather parallel; head and prothorax 

 slightly shining but without punctures, the latter with four deep 

 impressions upon its disk, possibly accidental. The elytra have four 

 fasciae — one basal, the second and third nearly straight, the fourth 

 formed of longer^ spots and diverging at the suture. These fasciae 

 are formed of five or sis elongate square marks separated by the 

 obsolete punctures, which are indicated by fuscous marks. There is 

 a sutural yellow line at the base and apex. 



This species somewhat resembles M. hogotce. Crotch : it is more 

 shining ; and the fourth fascia will distinguish it at once. I have only 

 seen a single specimen, which was sent me by Mr. E. Bartlett, by 

 whom it was collected in Peru. 



26. ISCHYRUS peruvianus. 



Elongatus, subcylindricus, nitidus, Jlavus, subtus nigro etferrugineo 

 variegatus ; capita, thoracis disco punctis quatuor transversim dis-
