I can detect no real differences between the Panama and Mexican specimens of this 
species which I have examined, nor between these and North-American or European 
representatives. According to Prof. Uhler%, it is quite common both in the eastern 
and western sections of the United States, and is found as far north as Lake Winnipeg. 
Stal also gives habitats ranging from California to Siberia; and even now that we have 
traced it to the mountains of Panama and Guatemala it may perhaps be accepted as a 
boreal species, whose presence in these Central-American mountains refers to southern 
migration at that Glacial period of which Belt found, and has described, so many 
evidences in this region. Mr. Dallas? had previously detected the specific unity of the 
European and North-American forms. 
2. Ischnorhynchus championi, n.sp. (Tab. XIX. fig. 3.) 
Head and pronotum pale ochraceous, thickly covered with dark punctures; head with apex, four short basal

ochraceous. Pronotum with two short, waved, transverse fuscous fascie near anterior margin. Scutellum 
pale ochraceous, thickly, coarsely, and darkly punctured at base, a few coarse dark punctures along lateral 
margins, and a central elongate fuscous spot. Corium pale ochraceous and semihyaline, with two fuscous 
spots on disk and four along apical margin. Underside of body pale fuscous, thickly and coarsely punctate, 
with an elongate black spot situated on lateral margins of pro-, meso-, and metasternum, and a series of 
black spots along abdominal margin. Metasternum very pale luteous and impunctate. Femora and 
apices of tibize castaneous, tibize and apices of femora pale ochraceous, apices of tarsi pitchy.
