The above measurements show that considerable size variation 

 is to be found in the species. The average smaller size of the 

 Brownsville series is almost certainly due to local environmental 

 conditions. This series is from the dense jungle brush of the river 

 plain; the much larger specimens, normal in this respect, from Mis- 

 sion, but sixty miles from Brow^nsville, were taken on gravelly 

 hillocks, in scattered scrub. 



Some variability is shown by the material before us in the con- 

 tour of various parts; often the margins of the pronotum, supra- 

 anal or subgenital plates show irregularities.
