7. Hammoderus maculosus. 
H. inermi affinis, sed major, elytrisque apice distincte et fortiter spinosis. Elongatus, ochraceo-fuscus, thoracis 
dorso vittis interruptis tribus, elytrisque utrinque maculis majoribus quinque (quarum una basali) pre- 
terea guttis numerosis, cretaceis; corpore subtus (prothorace, metasterno ventreque) lateribus cretaceo 
maculato. 
Long. 13-15 lin. ¢. 
Hab. Nicaragua, Chontales (Belt). 
Closely allied to H. albiplagiatus, White (=inermis, 'Thoms.), from which it differs 
by its greater size and more elongate shape, by the apices of the elytra forming distinct 
though stout spines, and by the more numerous and longer spots of the elytra. On each 
elytron there are five large white or yellowish-white spots, one at the base, one on the 
side before the middle, and another on the side behind the middle, sometimes united to 
the fourth spot on the disk a little nearer the base, and, lastly, a rather elongate spot 
near the apex. Besides these larger spots, which are nearly of equal size, there are 
many smaller ones scattered over the surface. The elytra are very scantily and faintly 
punctured; and the granulations near the base are smaller than in other species. ‘The 
central white vitta of the thorax is slender, and sometimes reduced to two linear spots ; 
the lateral vitta is broader, and sometimes reaches, without interruption, the anterior 
margin.

9. Hammoderus thiodes. | 
Rufescenti-fuscus, thorace utrinque linea abbreviata elytrisque singulis maculis quinque sulphureis, his 
basi crebrius punctato-granulatis, apice utrinque acute dentatis ; ventre maculis parvis lateralibus flavis.

Hab. Panama, Chiriqui (2ib0é). 
Clothed with finer and more silky tomentum, and of a more purplish-brown hue than 
the other species. The clear sulphur-yellow spots are more clearly defined, there being 
no spots of intermediate size between the five ovate ones and the few minute specks 
which are scattered over the surface. One of the five spots (as in H. inermis and allies)
