pattern is practically identical with that of C. scalaris, the pres- 

 ent species has a facies which makes it at once recognizable. 

 The form is shorter and much more convex than scalaris and 

 the elytra, on account of the coarser punctuation, look much 

 rougher. The pronotum and the elytral markings are a very 

 dark olive, while in scalaris these parts are bright green or blue- 

 green. The red color upon the elytra is only apparent upon 

 sexually mature specimens and disappears after death. The 

 claws are less widely divergent than in scalaris. The species 

 occurs but sparingly upon its food-plant. 



Calligrapha rowena, new species. 



Form subovate, convex. Color of the body and elytral pattern dark 

 blue-green, submetallic ; the legs, antennae, and palpi ferruginous yellow ; 

 labrum ferruginous. Ground-color of the elytra yellow ; in sexually 

 mature specimens the greater part of the disc is bright orange-red, 

 the anterior third and a broad outer margin golden. The elytral pat- 

 tern consists of a double sutural stripe to which is joined, behind the 

 anterior third, a short and heavy arcuate stripe ; before the posterior 

 third is a detached arcuate spot which represents the posterior branch 

 of the complete arcuate stripe of C. rhoda and C. scalaris; the spots 

 near the apex, which in rhoda are usually large and joined to the 

 sutural stripe, are either obsolete or small and detached. The humeral 

 lunule is short and very heavy, double to beyond the middle; it en- 

 closes a heavy, roughly lunate or rounded spot which is sometimes 

 fused with it. There is a large spot on the outer margin near its middle ; 

 the spots upon the disc are small and vary in number from 3 to 8 upon 

 each elytron, while in rhoda there are 10 or 11. The punctures limiting 

 the elytral pattern are coarse and the markings are more or less 

 convex. The punctuation of the disc is distinctly coarser than in rhoda 

 and consequently the surface is uneven. The epipleura are pale with 

 their outer margins ferruginous. The head and pronotum are aluta- 

 ceous, but more shining than in rhoda and coarsely punctured. The 

 punctures of the pronotum are rather sparse and those upon the disc 

 but little finer than the ones at the sides; half-way down the sides is 

 a depression with more or less confluent punctures and bounded by a 

 more or less impunctate area. The claws are more divergent than in 

 rhoda.
