Var. elytris sicut in E. metrico longioribus sig: 



Eab. Mexico, Jalapa {Edge). 



The variety from Mexico bridges over the difference between this species and 

 E. metricus. 



3. Euproctus quadrinus. (Tab- VIII. fig. 11.) 



fenestrello simillimus, sed differt elytrorum fascia mediana nigra duplo latiore et minus obliqua, maculisqne 



inclusis quatuor flavis minoribus. Fulvo-flavus, thoracis margine laterali fusco basin haud attingente; elytris 

 basi (margine inflexo flavo excepto) tota late nigra, margine suturali sicut in E. fenestrello sat lato, scutellum 



attingente ibique dilatato etc.; elytris adhuc latioribus, subtiliter punctulato-striatis, interstitiis planis. 

 Long. 3| lin. 



Eab. Panama, Volcan de Chiriqui (Champion). 



The black markings of the elytra form a similar pattern to that of the two preceding 

 species ; but the cross bar is much broader and less oblique than it is in either, and the 

 included yellow spots are less prolonged at their outer upper angles than in the allied 

 species. Further, the black basal border is not indented or subinterrupted by a yellow 

 basal spot (near the shoulders) as in the other two species. 



One example only. 



4. Euproctus ornatellus. (Tab. VIII. fig. 15.) 



Prsecedentibus proxime affinis, sed multo minor elytrorumque signaturis nigris multo latioribus. Subgracilis, 

 flavus, thorace lateribus late infuscatis; elytris nigris, utrinque margine angusto maculisque quatuor 

 ovatis flavis ; thorace sicut in prsecedentibus, anguste cordato, postice valde sinuatim angustato, angulis 

 posticis exstantibus acutis ; elytris subtilissime striato-punctulatis, interstitiis planissimis.

The black colour in th 

 surface ; and the pattern 



species occupies the chief part of the elytra! 

 lsequence, not as fine marginal and cross lines 



i yellow ground, but as four rather large oval spots on a black ground, the edges of 

 yellow spots being perfectly entire. 



5. Euproctus deliciolus. (Tab. VIII. fig. 13.) 



Subgracilis, fulvo-flavus, thoracis margine angusto elytrisque dimidio basali lineisque suturali submarginalique 

 (usque ad angulum suturale) nigris, relicta utrinque macula subapicali magna oblongo-ovata fulvo-flava ; 

 thorace sicut in prsecedentibus, anguste cordato, sed postice minus sinuato angulisque minus exstantibus ; 

 elytris subtilissime et obsolete striato-punctulatis (fere lsevibus).

In this distinct and beautiful species the basal part of the elytra (up to the extreme 

 basal and humeral rims) is deep glossy black, this colour being continued to the apex 

 (enclosing a large oval yellow spot) in fine submarginal and sutural lines ; the sutural
