[September 
dilated and with the first three segments biseriately squam- 
ulose below and the female usually with these tarsi unmodi- 
fied — but see under N. masculinus, below. The species of 
this subgroup differ remarkably among themselves in some 
other characters, as the following key shows. Incidentally, 
Mt. Spurgeon is probably the most northern locality at 
which any Notonomus has been found. 
Key to the species of Notonomus of the doddi subgroup 
1. Elytron with 9 normal intervals plus a narrow 10th 
submarginal one which does not reach base ... 2 
- Elytron with 11 intervals plus the narrow submarg- 
inal one (7th interval triplicate) 4 
2. Head and pronotum shining; elytral intervals not 
catenulate spurgeoni n. sp. 
- Head and prothorax dull; elytral intervals catenu- 
late 3 
3. Pronotum transversely striolate; elytron with 3rd 
interval 2-punctate doddi SI. 
- Pronotum longitudinally striolate; elytron with 3rd 
interval impunctate masculinus n. sp. 
4. Pronotum shining; elytral intervals not much caten- 
ulate (only 2nd interval crenulate on apical decli- 
vity) saepistriatus SL 
- Pronotum dull ; elytral intervals more extensively 
subcatenulate triplicatus n. sp. 
Notonomus spurgeoni n. sp. 
With characters of doddi subgroup (above) ; a little more 
slender than usual but otherwise of about average form 
and convexity for genus; purple or purplish above, piceous 
below, with appendages piceous to brownish-piceous ; rather 
shining; microsculpture fine and light (heavier on elytra), 
isodiametric in head and elytra, perhaps slightly transverse 
(but faint) on pronotum. Head normal for genus, .70 and 
.67 width prothorax in 6 $ measured. Prothorax a little 
wider than long (width/length 1.12 and 1.20 in ^ 9 meas- 
ured) but appearing as long as wide; base about 1/10 wider 
than apex; sides broadly and rather weakly arcuate for 
most of length, then straight or faintly sinuate near base;
