positis, duohus in margine antico, elytrorum macula magna scu- 

 tellari, altera parva infra humerum, puncto huic approximato, 

 fascia pone medium in sutura lata, ad marginem attenuata, limbo 

 tenuiter, apice latius nigris ; pedibus fulvis, femorum basi et 

 genibus nigris. 

 Long. 9| millim. 

 Hab. Peru. 



This species so far resembles 1. A-punctatus that it will be 

 sufficient to mention the characters which amply justify its di- 

 stinction from that North-American species. Its form is longer, and 

 its size larger ; the thorax, in addition to four spots, has two on the 

 front margin, and its base is not black. 



The elytral markings, though similar, are all different in shape ; 

 the narrow mark below the callus is on the margin ; and a round 

 spot in a line with the callus is in addition. The suture is more 

 widely black ; and the wide fascia has a projection in front on each 

 side of it. 



This insect was captured in Peru, but whether at Chancamayo or 

 not I am not certain. 



27. ISCHYRUS GRAMMICUS. 



Oblongus, subparallelvs, nitidtis, subtus rufo-piceus, supra rufo- 

 testaceus, capite nigra ; thoracis limbo tenuissimo maculis quatuor 

 transversis, duabus hasalibus triangular ibus ; elytrorum maculis 

 duabus baseos, una subscutellari, altera subhumerali, plagis 

 duabus rectis interstitialibus in medio maculisque tribus oblongis 

 {duabus sublateralibus, U7ia ante apicem), limbo toto tenuiter, sutura 

 et maculis duabus suturalibus {una oblonga, altera pone medium 

 rotundata) nigris; antennarum clava, tibiis geniculisgue nigro- 

 piceis. 

 Long. 9g millim. 

 Hab. Peru, Chancamayo. 



Punctuation fine but distinct under a strong glass, both on the 

 licad and thorax ; the latter transverse with the sides rounded, and 

 contracted near the front angles. Elytral striae rather distinct ; the 

 black lines are between the first and the second, a short one close to 

 the suture, often confluent, between the third and fourth and between 

 the fifth and sixth of equal length, in the middle or nearly so and 

 about equal to a third of the length of an elytron. The eighth stria 

 is not visible ; but following the seventh and hence in a line with the 

 subhumeral spot, are two spots parallel to the median line. 



28- Lybas? dorsalis. 



LcEte ferrugineus, prothoracis disco elytrorumque fascia lata 

 communi marginem haud attingente nigris, antennisfuscis, basi 

 rufis.

Hab. Peru, Chamicuros (Bartlett). 



Short, broad, and convex ; thorax with a few scattered punctures
