BULLETIN OF THE LABORATORIES 
posteriorly; surface smooth. Length of head, medianly, .50; 
breadth, .65 ; length of glabella, .35; width, .30. 
This species is said to be rather common in the Western states, 
but It has not yet been secured from Ohio. 
Phillipsich scitulci, Meek and Wovthen. 
Elliptical ; head semi-elliptical, tumid, one-third wider than long, 
anterior margin rounded, cheeks produced into spines extending to 
fifth thoracic segment ; glabella broadly rounded, occupying the mar- 
gin in front, most elevated posteriorly, axial sutures obsolete anterior- 
ly, posterior lateral lobes rather large, very oblique, lateral lobes al- 
most obsolete ; cervical segment more prominent than the glabella, 
with a median tubercle, cervical suture deep ; eyes one-half as long 
as the glabella; palpebral lobes semi-circular, convex; cheeks small ; 
pigidium almost as long as head, narrower, mesial lobe prominent, 
wider than lateral lobes, border wide ; surface granular. Entire length, 
.70; pigidium, .20; width of pigidium, .30; length of head, .25; 
width, .31. 
Judging from the figures and descriptions this species is the near- 
est approach to Grifhthides yet found in America. The presence of 
lateral furrows on the glabella indicate a member of Phillipsia, how- 
ever, as the genera are now understoood. 
Phillipsia doris, (Hall) Winchell. 
Head surrounded by an outwardly inclined border marked off by 
a deep groove from the cheeks, which are produced into spines poste- 
riorly one-third whole length of head shield; glabella prolatel}/ semi- 
elliptical, with large postero-lateral lobes, the lateral furrows indistinct; 
pigidium semi-elliptical, axial portion convex, diminishing to an obtuse 
point ; lateral lobes somewhat narrower, bordered by a smooth margi- 
nal area, axis with 1 1 articulations, lateral lobe 7 ; surface obscurely 
granulose, 
Winchell says, also “ middle of the border (of head) marked by 
a groove which reaches a point opposite one eye, to the corresponding 
point on the other side of the head,” which seems somewhat difficult 
to understand. The species was obtained from Rockford, Indiana. 
Width of pigidium, .55; length, ,21.
