Remarks. — This species may be separated from all its allies in 

 Lacordaire's eighteenth group by the very uniform pronotal punc- 

 tures, which show a tendency to form longitudinal rows on the pos- 

 terior central part of the pronotum. The little pronotal black spot 

 and the distribution of the dorsal coloration may help in its identi- 

 fication, 



CHLAMISUS YAGUAR. new species 



Figure 90 



A small species belonging to the same group as C. rogaguanus and 

 C. cribricollis; yellow with many well-defined black spots. 



Pronotum. — Seen from above, of triangular shape with the apex 

 broadly rounded; central area hemispherical, not grooved longi- 

 tudinally and somewhat corroded, owing to the presence of small 

 but deep confluent punctures, which do not occur on some irregular 

 small raised vermicular areas; seen from the side, the notal profile 

 semicircular, somewhat flattened on top. 



Figure 90. — Chlamisus yaguar, new species, holotype: a, Dorsal view, left side, indicating 

 color pattern; right side, showing microsculpture and irregularities; b, lateral aspect. 



Scutellum. — Flat and smooth. 



Elytra. — Somewhat narrower than the abdomen, the sides of which 

 are partly visible posteriorly; basal margin feebly toothed; the sutural 

 margin toothed in the posterior four-fifths; each elytron with the 

 usual irregularities of this group, arranged as may be seen in figure 

 90; between the ridges small nonconfluent circular punctures. 

 f, Head. — Flat, covered mth large but not very deep punctures, 

 uniformly dense over the whole surface; antennae moderately long, 

 the second and third joints short and opposite to each other; distinctly 

 saw-edged from the fourth joint.
