H. C. FALL. 43 



Size smaller, prothorax narrower, beak a trifle longer, antennal club 

 barely as long as funicular joints 2-7, pygidial groove nearly 

 attaining the apex (California, Arizona, New Mexico, Colo- 

 rado) niibifer. 



EUCLYPTUS Dietz. 

 The species of Eicclyptus, except testaceus, which I have not 

 sufficiently examined, are separable as below. 

 Size larger, about 2 mm. in length, elytra more than one-half longer 

 than wide, and almost two and one-half times as long as the 

 prothorax. 

 Last ventral segment moderately coarsely and closely punctate, 

 nearly or quite as long as the two preceding in the 9 , and 

 longer than the two preceding in the 6^ . 

 Last ventral of 9 broadly rather strongly tumid posteriorly, 

 that of the c? flat and without apical emargination (New 



Mexico) derivatiis. 



Last ventral of 9 nearly flat, becoming feebly broadly im- 

 pressed at middle apically ; last ventral of cf minutely 

 emarginate at apex. 

 Form stouter, elytra not widening appreciably posteriorly 



(California, Arizona) rntilus. 



Form, including legs, more slender, elytra widest at or a 

 little behind the middle ( 9 not known) (Colorado). 



.sejuiictus. 

 Ventral segments finely sparsely punctate, the last three subequal 

 in length in the 9 (cf not known) (New Mexico). 



equisectiis. 



Size smaller, H mm. in length, the elytra rather less than one half 



longer than wide and about two and one-fourth times as long 



as the prothorax ferriigineiis. 



As compared with ferrugineus ^ the size in iestaceus is evi- 

 dently larger, the prothorax is relatively a bit wider, the 

 last ventral a little longer, being distinctly longer than the 

 two preceding together ; the metasternum apparently more 

 coarsely punctate, not clearly visible in ferjiigineus. 



E. riitiliis n. sp. — Elongate oval, rufotestaceous, the metasternum 

 usually brown or piceous, lustre rather dull, pubescence recumbent, 

 not dense, and of a bright golden yellow color. Beak (cf ) about as 

 long as the prothorax, regularly moderately strongly arcuate, cylindri- 

 cal, rather densely punctate, the punctures tending to become con- 

 fluent longitudinally. Antennae (c?) inserted at apical two-flfths, 

 slightly more basal but evidently beyond the middle in the 9 , in which 

 sex the beak is a little longer and less densely punctured and more
