rounded, advanced in front of the eyes about one-third their breadth, the 

 frontal costa convexed, the distance between the anterior margin of the 

 frontal costa and that of the eyes widening considerably below ; the face 

 below imperceptibly continued and quite declined ; the apex is strongly 

 obtusely rounded. As seen in front, the frontal costa is sulcate rather 

 deeply, commencing near the apex, the branches are from here to the 

 middle ocellus sub-parallel, and not divergent as \\\ jalapa. Pronotum 

 with the dorsum anteriorly obtusely angulate, the sides a little convexed, 

 posteriorly subulate acute, passing the hind femora ; dorsum granulate, 

 with an indistinct longitudinal wrinkle on either side running i^arallel 

 with the humeral angles, otherwise scarcely rugose ; median carina 

 distinctly elevated, gradually but slightly arched between the shoulders, 

 sloping to the front margin ; anterior lateral carina near the front sub- 

 straight and subdivergent posteriorly ; humeral angles strongly sloping 

 laterally, as seen in front obtuse, between the shoulders convexed, the 

 median carina clouded with fuscous. Elytra almost smooth, dark 

 externally, marked with a minute light oblique line near the apex. Wings 

 extended beyond the apex of pronotum. Femora with the carina; 

 unchanged, the posterior femora quite large, the first and third articles of 

 Ahe posterior tarsi about equal in length, all the pulvilli of equal length. 



Length: body, (^ , 9 mm., pronotum 9.5 mm., post. fem. 5.5 mm. 

 Wings extending about one millimetre beyond the process of pronotum, 



making the total length 11 millimetres.

This species is so closely related to Tettigidea chichimeca, Sauss., 

 that I place it as a dimorphic form. 



A NEW POPULAR NAME FOR CLISIOCAMPA DISSTRLA. 

 For many years this insect has been popularly known as " the forest 

 tent-caterpillar." During the past two or three years it has attracted 

 much attention in New Hampshire, Vermont, and New York, from its 

 ravages in maple forests, city or village maple shade trees, and in many 

 orchards. In orchards it has often worked with its near relative, the 

 apple tent-caterpillar {Clisiocafupa americana). Every one who critically 

 observes the habits of these two species of caterpillars soon discovers that 

 "the forest tent-caterpillar" is a very misleading name for Clisiocampa 

 xiisstria, because its caterpillars never make a tent, while the apple 

 tent-caterpillars always do. Several who have seriously discussed these 

 insects recently have felt the necessity of a new popular name for 

 Clisiocampa disstria. Professor C. M. Weed, of New Hampshire, when 

 writing his recent excellent bulletin on the pest, asked me to suggest some
