42 EKOTYLIM. 



parvulis in margine antica, limbo laterali, elytris macula magna communi tribusque aliis (una subhu- 

 merali, duabus paullo post medium transverse dispositis), et sutura nigris. Long. 6 millim. 



Eab. Panama, Bugaba (Champion). 



Very nearly allied to I. septemsignatus, but more obsoletely punctured and with the 

 markings different. The head has no spot ; the thorax has two small spots upon the 

 front margin, and no basal marks of any kind. The two spots on the middle of the 

 elytra do not represent the one spot in I. septemsignatus ; they are placed further back % 

 The suture is very narrowly black, and that colour vanishes before the apex. The 

 underside and legs are pale, but possibly the unique specimen is not fully matured. 



One specimen. 



13. Ischyrus undulatus. (Tab. III. fig. 3.) 



Oblongo-ovatus, flavo-ferrugineus, subtus subtiliter punctatus; ore, antennarum clava, protboracis pimctis 

 quatuor (duobus anterioribus approximate, duobus posterioribus magis distantibus), elytris macula 

 magna scutellari communi, puncto bumerali et subapicali fasciaque mediana, valde attenuata, marginem 

 baud attingente, sutura pedibusque nigris. Long. 7 millim. 



Bab. Panama, Bugaba (Champion). 



Head red, finely and thickly punctured, the front edge blackish ; antennae pitchy, 

 their third joint and the club black ; thorax less densely and more deeply punctured 

 than the head, the four spots arranged in a trapezium, the two front ones being 

 nearest, and not touching the front margin. The punctured striae of the elytra are 

 very faintly impressed and obliterated at the sides and apex. 



This and I. nitidior, Crotch, are the only species of Ischyrus at present known to me 

 with the spots arranged on the thorax in this way. Allied to /. nitidior, Crotch, but 

 larger and differently punctured. A single specimen. 



14. Ischyrus pictus. (Tab. III. fig. 4.) 



Oblongo-ovatus, crebre sat fortiter punctatus, flavus; vertice, antennis, protboracis punctis duobus discoi- 

 dalibus et tribus basalibus, scutello, elytris macula scutellari communi subquadrata, gutta oblonga juxta 

 suturam pone medium, punctisque tribus (una humerali, una mediana prope marginem et una subapicali), 

 sutura, limbo tenui pedibusque nigris ; pectore picescente. Long. 6 millim. 



Hab. Guatemala, San Juan in Vera Paz (Champion). 



Eather broadly ovate and convex; the puncturing moderately strong, the striae 

 evanescent at the sides and apex of the elytra, but fine interstitial puncturing may be 

 seen. The mouth and palpi are pitchy ; the head is yellow above, but the base and the 

 whole margin of the epistome are blackish. The thorax is about twice as wide as long, 

 the sides not much rounded, narrowing in front ; the three basal spots are connected '. 

 along the base, the two outside ones being somewhat triangular. The tarsi are (as usual) 

 pitchy-red. The markings of the elytra need not be re-enumerated, as the figure gives 

 a very good representation of them. A single specimen.
