Type No. 21607, United States National Museum. 



This species is probably referable to Laemobothrium on ac- 

 count of the presence of the prominent swellings before the 

 eyes, the absence of motile muscular lobes on the under side 

 of forehead, and owing to the body length exceeding 5 milli- 

 meters. On the other hand, the shape of abdomen, outline of 

 front of head, almost entire absence of ocular emargination, 

 and the general markings, are much more suggestive of Phy- 

 sostomum, and our species may well be the link that obliterates 

 the present separation into the two genera. Perhaps nearest

Head slightly wider than long; ground color pale amber; ocular 

 emargination almost lacking, head suddenly and greatly contracted 

 abreast of the mandible bases, sides of forehead converging to the 

 evenly rounded convex front; temples at first diverging slightly, and 

 then converging to the sharply rounded occipital corners; occipital 

 margin deeply concave with a slight median convexity; antennae con- 

 cealed in fossae; labial palpi barely projecting; mandibles pale with 

 teeth blackish; antennal fossae rimmed medially and posteriorly with 

 heavy black borders extending inward and backward to form Y-shaped 

 blotches; a black, cleft blotch on each side at inner angle of forehead 

 contraction; occipital border margined with blackish brown bands 

 which give off short rudiments of occipital bands; in front of 

 mandibles a crescent-shaped fossa, convex anteriorly; two strong spines 

 arise at each frontal angle between which occur about 30 hairs and 

 prickles of various lengths, a score or more of long and short hairs 

 arise on the lateral prominences, two weak hairs at the front of each 

 antennal fossa, a long hair arising just over the emarginate eye, several 

 short hairs along the anterior half of temples, a long and a short 

 pustulated hair at the temporal angles, a long pustulated hair at the 

 base of the temporal lobe, and three or four longish hairs along the 

 temporal margins. 



Prothorax roughly quadrangular, a sharp constriction at each an- 

 terior angle forms a sort of neck-like extension which fits into the 

 occipital concavity; the posterior halves of the lateral margins con- 

 verge quickly and end in the posterior-lateral lubes which are
