Athysanus arctostaphyli Ball. 



Athysanus arctostaphyli Ball. Entom. News Vol. X, p. 172 (1899). 

 /itnysanns arctostaphyli OsboTii and Ball, wuio Naturalist ijl, 243. 



Smaller than vaccinii which it resembles in form and color pattern. 

 Maine specimens are darker, almost black, the light portions of the 

 head and elytra much reduced. Length $ 3.5 mm c? 3 mm. 



This species was taken on Mt. Katahdin at levels of 4700 and 5000 ft. 

 Two specimens were taken at level of 4750 by Mr. C. P. Alexander 

 and I secured one additional specimen at Ft. Kent. The Katahdin 

 specimens are darker and the fuscous markingis more confused than in 

 Colorado or Mt. Washington (N. H.) specimens but there seems no 

 sufficient basis to consider them distinct. The Ft. Kent specimen from 

 a much lower level than the Katahdin specimens is a trifle nearer in 

 distinctness of markings to the Colorado specimens. All are smaller 

 Hhan the type specimens from Colorado but agree quite closely with a 

 series that I have from Mt. Washington, N. H. 



Athysanus elongatus n sp. 



Similar in color and markings to arctostaphyli but much more elon- 

 gated. Black with yel'low or whitish lines and dots. Elytra much longer 

 than the abdomen. Length $ 4.5 mm. c? 3.25 mm., to tip of elytra. 



Head produced, distinctly angulate, one-half longer at middle than 

 next the eye but length at middle less than half the width between the 

 eyes ; pronotum strongly arched in front slightly emarginate behind ; 

 elytra long, apical cells long and entirely beyond the tip of abdoimen. 



Color: — black, ocelli red, ring around the ocellus, oblique and median 

 lines meeting at the apex, two round spots back of ocelli and two short 

 clongately triangular transverse spots between them on vertex, yellow ; 

 numerous minute irrorations on pronotum, four central dots and four 

 marginal dots on scutellum, yellowish white ; veins of elytra and cen- 

 tral part of areoles whitish or subhyaline ; front black, with small 

 whitish arcs ; clypeus Avith two- basal spots and lorae with submarginal 

 spot whitish the four forming a transverse row ; median line of front 

 and sutures faintly whitish ; apex and subapical spot on femora whitish 

 as are the bristles of the tibiae. 



Genitalia : Female last ventral segment equal to preceding, truncate. 

 Male valve short rounded behind; plates narrow three times as long as 

 valve, pointed at tip, narrowly ciliate. 



Except for the extreme difference in form this species might be con- 

 sidered as a very long form of arctostaphyli. Specimens were taken at 

 Orono, Maine, July 3rd, 1914; Mt. Katahdin at 4700 and 5000 ft. Aug. 

 2ist; Portland Aug. 13th, Cherryfield on blueberry Sept. 5th, Ft. Kent 

 Aug. 29, 1913. A specimen was collected by Prof. H. G. Barber, Mt. 

 Katahdin Aug. 19th, 1902 and he has also sent me a specimen labeled 

 "Dilley Ore," which evidently belongs here though the latter, with one 

 specimen taken at Mt. Katahdin between 1000 and 1500 ft. have the 

 spots on the face larger and yellowish spots on side of last ventral 

 segment and pygofer of female.
