which was taken near Peekskill. Obscurus Lee., is represented in 

 my collection by a single apparently authentic male, 10.0 by 3.0 

 mm. in size, taken at an unrecorded locality in California; it agrees 

 well with the original description quoted above, except that the small 

 basal smooth spots of the pronotum, though very evident, are not 

 at all convex or callus-like, and that it is somewhat shining; grandis 

 is probably sometimes confounded with obscurus, but is quite dif- 

 ferent in its more parallel elytra, less prominent humeri, uniform 

 punctuation and absence of basal thoracic smooth spots, as well as 

 in its materially larger size. 



Variabilis is normally pale testaceous in color, with the entire 

 elytra deep steel-blue; forms wholly pale occur however, as in 

 Hylotrupes bajulus and Gonocallus collaris, but I have never noticed 

 any definite inconstancy of that kind in the other species of 

 Phymatodes, although the basal region of the elytra seems to vary 

 from black to testaceous in a number of species; diffidens, of the 

 above table, differs from the normally black varius, however, in 

 some structural characters; for example, the isthmus connecting 

 the upper and lower parts of the eyes in varius has the facets of its 

 single line large, widely spaced and transversely oval, while in 

 diffidens they become very close-set though still in single line. 



Luridus Rossi, in our lists under the name thoracicus is an 

 importation that seems to be still but rarely met with and may 

 not be thoroughly established thus far; it is piceous in color, the 

 prothorax rufous, with brownish spots laterally and the male 

 antennae are very slender and unusually long. 



The remarks made under my original description of obliquus 

 resulted from a confusion of specific forms. The male type of 

 obliquus is labeled simply " Cal." From Sta. Clara Co., there are 

 three examples, one a male with bicolored 'elytra, formerly placed 

 w T ith decussatus and two large females with entirely black elytra, 

 previously regarded as females of the male obliquus type, but erro- 

 neously as is now evident; these three are the above described 

 cotypes of harfordi. 



It is almost a certainty that semicircular is Bland (Proc. Ent. Soc. 

 Phila., 1862, p. 9), if not founded upon an extraordinary aberration 

 or sport, which seems unlikely, is a species not only distinct but of 

 a different genus. The type if still in existence should be studied 

 more attentively.
