FALSE WIREWORMS OF PACIFIC NORTHWEST. 81 
depressed, faintly striate. Caudal segment scutelliform, slightly convex dorsally, 
margined laterally, tip curved slightly upward, bearing 18 acute spines on margin— 
4 groups of 2 spines each on each lateral margin and 2 spines at tip. A number of 
hairs on dorsal surface and many on ventral surface. Head subquadrate, very convex, 
sides converging anteriorly, posterior angles rounded, 2 hairs on lateral dorsal and 
several hairs on ventral surface; 2 black eye spots on lateral anterior part of head, a 
large oblong one at the base of antennz, and a smaller square one posterior and dorsai 
of this. Suture arising at the base of each mandible flexed laterally and converging 
posteriorly to unite with median suture near base of the head. Basal joint of labrum 
trapeziform, terminal joint rounded, trilobed, hairs on margin. Mandibles large, 
visible from above. Ligula broader than palpifer, labial palpi cylindrical, 2-jointed,

tum. Legs 4-jointed. Second joint of anterior legs with 2 short stout spines on inner 
anterior margin; third joint of anterior legs with 3 longer spines on inner margin, and 
fourth joint with 3 still longer, stout spines; 2 spines on inner side and 1 spine on outer 
side of base of claw. 
The pupa.—The pupa of this species is very similar to that of Eleodes letcheri van- 
dykei, from which it can be distinguished, however, by a pair of rather stout spines at 
the apex of the secondary wing pads. 
The adult (Fig. 27).\—The following description is from page 384 Dr. Blaisdell’s 
monograph previously mentioned in this paper: 
Moderately robust, ovate, feebly shining to opaque, about twice as long as wide; 
prothorax more or less strongly constricted at base, densely rugoso-punctate; elytra
