21. Prothorax with lateral spine, flying hairs long Pogoiiocherus. 



Prothorax with feebly rounded sides, pubescence short Ecyrus. 



2 2. Eyes not divided, prothorax not distinctly tuberculate, form 



slender Oberea. 



Eyes completely divided, the upper and lower portions widely sepa- 

 rated, prothorax with large lateral tubercle, form stout. Colour 

 red with black spots Tetraopes. 



Ipochus, Lee. 



A record of the Californian species /. fasciaius, Lee, is existent 

 upon the Society's list, but I am unaware of the original authority. It is 

 a convex, heavily-built beetle, blackish, pubescence long, erect. Pro- 

 thorax with large punctures, and bearing a transverse row of four spots 

 of white pubesence. Elytra with irregular transverse bands of whitish 

 pubescence, varying in width. Length, .18-.30 inch. 



Cyrtinus, Lee. 



Represented by one extremely small, somewhat antlike species, C. 

 pygnuetis, Hald., easily recognized' by the convex elytra with rounded 

 humeri and large juxta-scutellar spine. Colour nearly black, elytra with 

 a whitish pubescent spot before the middle, antennte annulate. Length, 

 .08-. 1 2 inch. Said to occur on dead oak branches. 



PsENOCERUs, Lee. 



P. supernotatus, Say (fig. 30), is recorded as boring during larval 

 life in the stems of grape, currant, gooseberry, and apple. I have 

 frequently beaten it from crab-apple trees. It is a 

 small beetle of somewhat elongate form, reddish to 

 nearly black, the elytra with a darker blotch behind """^"^ 

 the middle which is bordered anteriorly and pos- 1^ i 

 teriorly by a band of whitish pubescence, the anterior 

 band usually much the narrower and interrupted ^"^' 3°- 



near the suture. Antennae shorter than body in both sexes. Small 

 specimens are often almost entirely black, and may lack the elevation at 

 the base of the elytra. Length, .12-24 "^ch. 



MoNOHAMMUS, Serv. 



Includes several very large species with long legs and antennae, 

 especially in the males. Some or all of them are injurious to pine 

 lumber, and smtellattis and confusor are usually abundant in the eastern
