178 HEMIPTERA-HOMOPTERA. 
A large, subparallel species ; metopidium compressed and produced almost in a hook; pronotum at its broadest 
about as broad as long; tegmina unicolorous nigro-sneous, with the apical part strongly reticulate- 
rugose ; legs and abdomen ceruleous, the former partly reddish, the latter with reddish spots at the sides. 
Long. 19 millim.; lat. max. 9 millim. 
Hab. Costa Rica (Van Patten). 
Group 2. 
This group might perhaps be included under the preceding ; the species referred to 
it, however, are smaller, and 7. mylabroides and T. preminiata are very distinct in 
general appearance. 
7. Tomaspis intermedia, sp. n. 
Sat lata, nigra, nitida, metopidio vix producto, basi pronoti, humeris fasciisque duabus angustis sat obscure 
luteis; pronoto levigato, leviter remotius punctato; tegminibus sat parallelis, antice fortius, postice 
perdensius punctatis ad apicem leviter rugoso-reticulatis ; corpore subtus pedibusque piceis. 
Rather broad, black, with the metopidium (which is scarcely produced), the base of the pronotum, shoulders, 
and two straight and rather narrow bands (one at and one behind the middle) obscurely luteous ; pronotum 
shining, broader than long, somewhat remotely and shallowly punctured; tegmina rather strongly 
punctured and shining in front, thickly punctured and duller behind, very slightly rugose at the apex ; 
underside and legs pitchy. 
Long, 14 millim.; lat. 8 millim. 
Hab. Panama, Bugaba (Champion). 
_ A somewhat unsatisfactory and intermediate species, with an affinity towards T. inca, 
and yet resembling certain members of Group 8. It would be classed as a Monecphora, 
but the metopidium is slightly produced, though not compressed. 
8. Tomaspis mylabroides, sp.n. (Tab. XI. figg. 7, 7a.) 
Elongata, parallela, capite antice flavo, postice cum lateribus ante oculos antennarumque basi nigris; pronoto 
nitido, longitudine latiori, leviter punctato, nigro, tertid parte anteriori flava; scutello flavo, postice nigro ; 
tegminibus nigris, parte humerali late, et fascia sat lata ad medium, flavis, dense et distincte punctatis ; 
corpore subtus antice rufo-flavo, abdomine nigro; pedibus nigris vel piceis, femoribus totis vel ad partem 
rufo-flavis. 
A moderately elongate, parallel species, with the head black at the sides and at the base, and yellow in front ; 
metopidium slightly compressed and produced; pronotum smooth and shining, the apical third in front 
yellow, the rest black, the division being usually abruptly marked, the punctuation somewhat remote and 
shallow; scutellum yellow, except at the apex; tegmina black, with the front part and a broad fascia at 
the middle yellow, very closely punctured, especially behind, the apex very slightly reticulate; underside 
reddish-yellow in front; abdomen black; legs black or pitchy, the femora entirely or almost entirely 
reddish-yellow. 
Long. 153 millim.; lat. 8 millim. 
Hab, Nicaraaua, Chontales (Janson); Panama, Caldera (Champion). 
The specimen from Nicaragua has the anterior portion of the pronotum black in the 
middle. An example from Caldera is figured.
