PHYTOPHAGA. 



Head very minutely punctured ; antennae slender, two thirds the length of the body testaceous ; thorax trans- 

 versely subquadrate, the anterior angles acute and produced, the surface extremely finely punctured ; elytra 

 with ten rows of regular and deep punctures, the striae more closely approached at the sides than on 



the disc. 

 Hob. Mexico {Salle). A single specimen. 



The figure referring to the present insect gives a better idea of the design of the 

 elytra than a description. The species cannot be mistaken for the North-American 

 B rhois, Forst., on account of its larger and more elongate shape and that of the 

 thorax, which is quite differently formed ; the latter in the North-American species is 

 not semiquadrate, but narrowed in front, and has some deeply impressed punctures 

 placed on its disc ; the posterior margin of the thorax in B. reticulata is slightly, but 

 evenly, rounded, and not oblique as in B. rhois. 



3. Blepharida mexicana. (Tab. XXII. fig. 16.) 



Testaceous; head and thorax very finely punctured; elytra strongly punctate-striate, the sutural and lateral 

 margins and three longitudinal rows of interrupted spots on each elytron dark fulvous. 



Length 3|-4 lines. 



Head extremely finely punctured; apices of the mandibles black; frontal tubercles obsolete; antennae two 

 thirds the length of the body, testaceous, the third and fourth joints equal ; thorax three times as broad 

 as long, narrowed at the base, the sides rounded before the middle, the anterior margin straight, its angles 

 acute, but scarcely produced, the 'surface very finely and irregularly punctured; scuteUum fulvous ; elytra 

 convex, subquadrate-ovate, each elytron with ten rows of regular and distinct punctures (the first very 

 short), the spaces between the third, fifth, and seventh rows occupied by irregular-shaped longitudinal 

 dark fulvous spots, which are sometimes connected by transverse branches ; the sutural and lateral margins 

 are also, although narrowly, of the same colour. 



Eab. Mexico, Cordova (H'dge, Salle). 



The shape of the spots on the elytra in this species is very irregular and variable, but 

 always disposed in three longitudinal rows ; a small spot at the humeral callus and 

 another more elongate near the scutellum seem to be constant. 



4. Blepharida trifasciata. (Tab. xxil. fig. 14.) 



Subquadrate-ovate, convex ; thorax flavous, margined with piceous ; elytra deeply punctate-striate, flavous, a 

 spot at the shoulder, and three obliquely-shaped transverse broad bands not extending to the lateral 

 margin, fulvous. 



Length 3 lines. 



Head distinctly and rather closely punctured, flavous, a central longitudinal band and the space surrounding 

 the eyes fulvous ; antennas nearly two thirds the length of the body, fulvous ; palpi slender, filiform ; thorax 

 more than twice as broad as long, the sides rounded and narrowed in front, the anterior angles produced 

 into a short tooth, the disc closely and strongly punctured, here and there with some irregular depressions, 

 flavous, all the margins accompanied by a row of piceous spots, of which some are also placed at each side 

 obliquely and anteriorly ; scuteUum fulvous ; elytra with ten rows of deep, but not very closely placed, 

 punctures, flavous, the three fulvous bands broad, of oblique shape, the first before, the second behind 

 the middle, and the third near the apex, the last two bands very irregularly shaped at their margins, and 

 interrupted by the flavous ground-colour, a fulvous spot is also placed at the shoulder, and the lateral 

 margin and elytral epipleurae are of the same colour, as well as the underside and legs.
