54 MALACODERMATA. 
2. Aspidosoma zgrotum. (Tab. III. fig. 16.) 
Aspidosoma egrotum, Gorh. Trans. Ent. Soc. 1880, p. 84. 
Hab. Mexico, Oaxaca (Sallé); Guatemaa (Sallé), near the city, Capetillo, Purula, 
San Gerénimo (Champion); Nicaracua, Chontales (Janson). 
3. Aspidosoma diaphanum. 
Aspidosoma diaphana, Gorh. loc. cit. p. 86. 
Hab. Muxico, Tuxtla (Sailé); Britis Honpuras, river Sarstoon (Blancaneauz) ; 
Gvuatemata, Purula, Cubilguitz, Sabo (Champion) ; Nicaragua, Chontales (Belt). 
Very close to A. wgrotwim ; separated chiefly on account of its smaller size and more 
distinct markings. 
4. Aspidosoma depictum. (Tab. III. fig. 17.) 
Aspidosoma depictum, Gorh. loc. cit. p. 85. 
Hab. Costa Rica, Volcan de Irazu (Rogers). 
A pretty and very distinctly marked species; the specimens of A. diaphanum from 
Purula are very much like it. The basal subhumeral spot is more distinct; and the 
posterior lateral fuscous spot is longer and more irregular in shape. 
5. Aspidosoma pulchellum. (Tab. IV. fig. 15.) 
Aspidosoma pulchellum, Gorh. loc. cit. p. 86. 
Hab. Mexico, Cordova, Santecomapan (Sal/é); Brrrish Honpuras, river Sarstoon 
(Blancaneaus) ; Nicaracua, Chontales (Janson). 
The elytral margin is pale, without lateral spots; sometimes, however, it is fuscous; 
and this species then very much resembles a small Hyas angularis. The fifth ventral 
segment, or fifth and sixth, are luminous in the female. 
6. Aspidosoma lepidum. 
Aspidosoma lepida (Chevy. ined. coll. Sallé). 
Ovale, piceum, nitidum, prothorace flavo, macula laterali et disco piceis, elytris sutura tenuiter, margine in 
medio, apiceque extremo testaceis. Long. 7-8 millim. ¢ 9. 
Mas abdominis segmentis ventralibus quinto et sexto lete flavis, eburatis. 
Femina segmento quinto medio albido-flavo. 
Hab. Mexico, Campeche (Sad/é); Guatemaua, San Gerénimo (Champion). 
This little Aspidosoma is easily recognized by its very small size, and the rather 
distinct markings. The head and two or three basal joints of the antenne are pale, 
pitchy fuscous in the male, but dark in the female, as is also most of the body, 
excepting the luminous portion, which, especially in the male, is very clear yellowish 
white and shining. The thorax is rather coarsely punctured, the discoidal patch
