claws on all tarsi, the median claw consider- 
ably more slender and erect than the lateral 
claws; lateral claws with a fringe of hairs 
along the outer margins, median claw also 
appearing hirsute under oil immersion. 
type locality: Spencer’s Butte, Eugene, 
Oregon (holotype larva). The type and only 
specimen was found in material beaten from 
shrubs, July 10, 1952, collected by the writer. 
Since Lassenia lasseni has larvae of the self- 
detaching type, it is probable that the present 
species has this same habit. Therefore it is 
impossible to say whether the larva was actually 
crawling on the shrubs or whether it was 
attached to a host insect which happened to 
be on the shrubs. It had obviously been 
feeding. 
remarks: It is possible that this is the 
larva of L. spinifera , but since the locality 
records for the two are quite different, it is 
best not to correlate the larva and adult at 
this time. L. scutellata and L. spinifera are at 
present known only from the state of Oregon. 
L. scutellata can be readily differentiated from 
L. lasseni on the basis of the characters dis- 
cussed under the remarks following the de- 
scription of the type species. 
Figs. 249-254. Lassenia scutellata n. sp., larva: 249, dorsum; 250, gnathosoma; 251, venter; 252, tarsus of palp, 
posterior; 253, tarsus of palp, distidorsal; 254, cyst-like object of unknown nature attached to palpal eupathid, 
probably fungus or protozoan.
