description the eleventh (first lateral) stria of elytra is said to 

 become obsolete behind the middle, whereas in the specimens 

 before me each elytron has but ten striae, the tenth in these be- 

 comes obsolete behind the middle. The structure of the antennae 

 is as described by Spinola, the basal joint is large, the second, 

 third and fourth small, the fifth to tenth mucn larger, about one- 

 third longer than wide and triangular in ionn, the eleventh joint 

 one-third longer than the tenth. Thus they agree with Spinola's 

 species in having the seven outer joints serrate. The species 

 occurring in Mexico, in which the outer eight joints are serrate, 

 is in all probability a different insect. Tn typical specimens the 

 color is black, the disk of the thorax alone being red ; here the 

 specimens are black varying to piceous, the entire prothorax, coxae 

 and base of femora pale red, with the head between the eyes dull 

 red. The specimens agree with the type in size, ranging from 

 4.17 — 5.5 mm. in length. This species might easily be mistaken 

 for a small species of Cymatodera. The form of the claws, finely 

 granulated eyes and entire labrum should, however, suffice to dis- 

 tinguish it generically. 



3. Cymatodera pubescens sp. now 



Dark brown, body beneath, abdomen, antennae and legs pale red- 

 dish brown, clothed with very fine, short but very dense recumbent yel- 

 lowish pubescence. Head and thorax minutely and very sparsely 

 punctate, eyes prominent. Antennae slightly longer than head and 

 thorax, joint two, three, and four small, joint two smaller than joint 

 three and equal to joint four, joints five to ten larger, elongate, scarcely 

 serrate, joint eleven one-third longer than joint ten. Prothorax one- 

 half longer than wide, much wider at apex than at base, apical con- 

 striction very feeble, basal constriction very strong, apical and basal 

 transverse impressed lines nearly obsolete, ante-scutellar impression 

 wanting. Scutellum orbicular. Elytra at base nearly twice as wide 

 as base of prothorax, humeri distinct, sides parallel, apices conjointly 

 rounded, disk feebly convex, each elytron with ten rows of rather 

 coarse, closely placed, subquadrate punctures which become but slightly 

 smaller posteriorly and extend very nearly to extreme apex, intervals 

 convex, at base subequal in width to punctures, posteriorly slightly 

 wider, finely irregularly punctate. Body beneath coarsely rather 

 sparsely punctate ; abdomen finely more densely punctate ; under sur-
