THE PROVANCHER COLLECTION OF HEMIPTERA  I4I 
from this label, but there can be no question that is the 
male of americana Fitch. 
275. Platymetopius acutus Say, correct. 
275. Platymetopius magdalensis, n. sp. This is the 
species later described by Prof. Osborn as obscurus. 
276. Scaphoideus immistus Say, correct. 
277. Scaphotdeus auronitens, n. Sp., correct. 
278. Deltocephalus curtisit Kh., correct. Afhysanus 
curéisit Fh. 
278. Deltocephalus inimicus Say, correct. 
279. Deltocephalus citronellus Prov. The insect on this 
label is a 7amnotettix probably still undescribed. It is 
not the form described in the NAT. CAN., p. 378. 
279. Dellocephalus minkii Fieb., correct. 
280. Dellocephalus sayt Fitch, correct. 
280. Selenocephalus placidus, n. sp. This is an Acuce. 
phalus new to me. It has a dark shade under the sharp 
lunately rounded anterior margin of the vertex and the 
apex of the elytra are coarsely alternated with fuscous points 
which are not properly iudicated in Provancaer’s descrip- 
tion. It may be one of the European species already reco- 
gnized from this country. 
281. Athysanus obsoletus Kixsch. is now known as 7e/a- 
hivus Gill. & Baker. 
282. Athysanus plutonius Uhler. This has more recen- 
tly been separated out as a distinct species under the name 
uhlert Ball. 
282. Acocephalus circumflexus n. sp. is the male of 
albifrons LAnn. 
283. Thamnotettix citronellus Prov. Under this name 
is a very pale specimen of eburata Van D., but it does not 
answer to the description in the NAT. CAN., p. 378, and 
cannot be that insect. 
284. Thamnotettix clitellarius Say, correct.
