Type: American Museum of Natural History, seen; type locality: Puerto 
Rico, Luquillo Mtns., El Yunque, 1800 ft. 
Description (diagnostic characters only). With the characteristics 
of the subgenus Antilliscaris. Forms as in Fig. 4. Head: antennae 
long, extending to about middle of peduncle, apical segments inter- 
mediate between danforthi and megacephalus , L/W of segments 4-10 
between 1.3 and 1.9 (Fig. 9). Vertex: 3 pair of setae, clypeal, supra- 
orbital and a pair halfway between the two and closer together than 
either. Lateroclypeus and antero-lateral halves of vertex with a 
series of irregular striations. Without a large depression behind the 
eye and a deep pit at the posterior end of scrobe. Prothorax : lateral 
grooves narrow but distinct with 5 or 7 pairs of setiferous punctures, 
posterior angles small. Sternum: 6-8 setiferous punctures clustered 
in front of the intercoxal spine, the latter with 6-8 setae. Elytra: 
surface dull, anterior margin with dense band of coarse tubercles in 
addition to the tubercles associated with setiferous punctures. Lateral 
groove: dense concentration of tubercles, 7-8 setiferous punctures on 
third interval. Striae lightly impressed. Pterothorax: mesasternum, 
2 setiferous punctures; metasternum 6-7 setiferous punctures. Ab- 
domen: 1st and 2nd intersegmental sutures normal. 
Measurements. Head: length 2.7-3. 1 mm, width 3. 6-4.0, length/ 
width O.75-O.77. Mandible: length 2. 3-3.0. Prothorax : length 3.1- 
3.5, width 4.0-4.6, length/width 0.77-0.76. Elytra: length 6.9-7-9, 
width 4. 2-4. 8, length/width 1.64-1.64. Total length (including 
peduncle) 15.4-18.0 mm. Measurements reported: extremes in total 
length of the four specimens measured. Specimens examined: holo- 
type and three others (M.C.Z. ). A specimen, currently alive, about 
12 mm in total length, has not been examined critically. 
Distribution: El Yunque, 1800 ft. to summit (3493 ft.). 
Larva: Three presumably second instar Scarites were collected 
on El Yunque, one in a decayed log in cloud forest c. 2200 ft., and 
two others under rocks along a forest trail c. 3200 ft. Based on 
size (head capsule of preserved larve 1.9 mm wide) these larvae are 
probably mutchleri.
