500 BRUCHIDES. 
17. Spermophagus dytiscinus. (Tab. XXVI. fig. 22.) 
Ovalis, convexus, fuscus ; minus dense griseo pubescens, ochraceo guttatus ; prothorace valde transverso, ubique 
fortiter punctato ; prosterni processu elongato, acuminato. 
Long. 4 millim. 
Hab. Brirtsn Honpvras, Belize (Blancaneaux); GuateMALA, Chacoj in the Polochic 
valley (Champion). 
Antenne rather short, red; eyes only moderately large, coarsely facetted, widely 
separated in front. Thorax very short, rounded and narrowed at the sides in front, 
furnished in addition to the minute punctuation with larger punctures which exist on 
the middle as well as at the sides, covered with a rather scanty griseous pubescence, 
and some indefinite ochraceous spots. Elytra rather deeply striate, the strie at the base 
distinctly crenate, the alternate interstices with rather numerous spots of ochraceous 
pubescence. Pygidium concolorous with the elytra, not spotted. Front coxe rather 
widely separated, terminating behind as a sharp spine projecting on the apex of the 
metasternum, somewhat after the fashion normal in the family Dytiscide. 
Only four examples were met with. The species bears an excessive resemblance to 
S. luctuosus, from which it is perfectly distinguished by the prosternal process. . 
18. Spermophagus scutellaris. 
Ovalis, angustulus, rufo-testaceus, griseo pubescens, sepius circa scutellum plaga magna fuscula; elytris vage 
minuteque fusco subguttatis ; pygidio medio longitudinaliter vage fusco signato. 
Long. 33 millim. . 
Hab. GuatEMA.a, near the city, Capetillo, Duefias, Zapote, Cerro Zunil (Champion) ; 
Nicaragua, Chontales (Janson); Panama, Bugaba (Champion). 
Antenne rather feeble, yellow, the second joint about equal to the third. Head 
with moderately large, convex, coarsely facetted eyes. Thorax strongly transverse, very 
densely and minutely punctured, finely griseo-pubescent, not spotted, with very faint 
indications of larger punctures at the sides. Elytra very finely striate; pygidium 
concolorous with the elytra, with a longitudinal and rather indefinite fuscous mark on 
the middle. Scutellum narrow, small. 
S. scutellaris may readily be distinguished from the preceding species by the dimi- 
nished size of the third joint of the antenna. The front coxe are only slightly separated ; 
the process is only slightly prolonged backwards behind them, and is received on the 
front of the mesosternum a little above its apex; the longer spur of the hind tibia is 
rather short. Mr. Champion secured ten examples at Capetillo ; but we have only one 
or two individuals from each of the other localities. All the examples from Guatemala 
have an irregular triangular dark mark round the scutellum; this is much reduced in 
size in the two exponents from Nicaragua, and is completely absent in the unique 
example from Bugaba. 
19, Spermophagus centralis. (Tab. XXVI. fig. 23.) 
Ovalis, fusco-ferrugineus, griseo vestitus, vage albido maculatus; antennis rufis; prothorace subtilissime punc-
