as shown by a large number of specimens sent some years ago to the late 
George Franck and collected by A. Kusche at Shasta Springs in May. 
DoNACiA VERMICULATA new species. 
Elongate; color above aeneous, antennae reddish, except the first 
joint, following joints more or less distinctly darker at apex, legs reddish, 
femora in about apical half metallic. 
Head slightly prolonged behind the eyes, feebly arcuately narrowing 
to the neck and moderately deeply constricted; eyes moderately promi- 
nent; median line fine and deep; surface finely punctate-rugose; an- 
tennae not reaching the middle of elytra, third joint distinctly longer 
than second, slightly shorter than fourth, which is as long as the first 
joint. 
Prothorax dull, about as wide at apex as long; anterior angles 
distinct not prominent, feebly rounded; posterior angles slightly promi- 
nent; lateral tubercles feebly distinct, separated from the disk by a 
shallow impression; median line absent; transverse basal impression 
very feeble, except at middle; sides below the tubercles distinctly but 
not strongly converging to base and slightly arcuate ; surface very densely 
and very finely strigate, producing a dull appearance, with moderately 
large punctures, which are more sparse at middle than at apex and base. 
Elytra without dorsal impressions; the coarse transverse rugae 
absent; intervals finely and closely vermiculate-rugose, denser near 
apex, near the scutellum finely punctate; lateral margin from a postero- 
lateral view acute not quite to the middle, thence to apex gradually 
transversely arcuate. 
Body below densely punctate and sparsely pubescent with short 
cinereous hairs; side pieces of presternum anteriorly very finely and 
densely strigate and laterally with a few punctures, posteriorly coarsely 
strigate; posterior femora reaching to apex of third ventral segment, 
distinctly clavate and narrower at base than at apex, without tooth below. 
Length: 7 mm. 
Male: Unknown. 
Female: Last ventral and dorsal segments broadly rounded at apex; 
vaginal plates as in emarginata. 
California: "Cal." (Ricksecker). 
A single specimen in the collection of the late Ottomar Dietz, which, 
judging from the handwritten label on the specimen, came from Rick- 
secker. 
This species is very near longicollis and I have long hesitated to
