18. Belonuchus mexicanus. 
Belonuchus mexicanus, Solsky, Bull. Soc. Mosc. 1864, i. p. 440°. 
Hab. Mexico}. 
Though I have seen no insect answering to this description, I believe it will prove 
to be an ally of B. deectus. 
19. Belonuchus mimeticus. (Tab. XI. fig. 14.) 
Subdepressus, rufus, nitidus ; capite eneo, antennis in medio fuscis ; antennarum basi, ore pedibusque testaceis ; 
elytris dimidio apicali nigricante ; abdomine ante apicem nigro, apice flavo. 
Long. 7-73 millim. 
Hab. Panama, Bugaba 800 to 1500 feet (Champion). 
Antenne moderately long; the three basal joints yellow, the next six fuscous, the two 
terminal fuscous yellow; the tenth joint about as long as broad. Mandibles and palpi 
yellow. Head short and broad, of a dusky-brassy colour, but very shining, with a few 
coarse punctures about the hind angles. Thorax rather short, yellow-red, much narrowed 
behind, a little produced in the middle in front, on each side of the middle with a 
discoidal series of five large punctures, and with four or five other punctures near the 
front angle. Elytra coarsely punctate, fulvous-red, with the apical portion broadly and 
indefinitely black. Basal segments of the hind body sparingly punctate; terminal 
segment pale yellow, the two preceding it black, but the hind margin of the penultimate 
yellow; the black parts rather coarsely setose; apices of anal styles fuscous. 
The male has a minute prominent tooth on each side of the clypeus in front; the 
anterior and posterior femora spinose, and a broad shallow emargination on the ventral 
plate of the last segment. The femora of the female are without spines. 
20. Belonuchus pictipennis. 
Subdepressus, rufus, nitidus; capite eneo, antennis fusco-rufis, harum basi, ore pedibusque testaceis ; elytris ad 
apicem macula magna nigra; abdomine ante apicem nigro, apice flavo. 
Long. 8 millim. 
Hab. Panama, Bugaba (Champion). 
This is very closely allied to B. mimeticus, but is rather larger, and the black colour 
on the elytra forms a definite spot limited to a smaller space. . 
The male has a very broad head, without teeth on the clypeus; the femora very 
strongly armed with Jong spines; the emargination on the apical segment very slight ; 
and the palpi extremely elongate. 
Only two males have been found. 
21. Belonuchus similis. (Tab. XI. fig. 15.) 
Rufus ; capite thoraceque nigro-eneis, nitidissimis; antennarum medio, elytrorum postico abdominisque fascia
