DIESTOTA. 249 
This insect has much the appearance of such species of Homalota as H. testaceipes, 
Heer. According to the series before me, it varies somewhat in size and in colour, 
more especially in the colour of the wing-cases, which sometimes have only a small 
pale humeral spot, while in other cases the yellow colour extends itself in a vague 
manner over the greater part of the wing-case. 
4. Diestota foveata. | 
Fusco-rufa, capite abdominisque apice nigricantibus, antennarum articulo basali pedibusque rufis; antennis 
brevibus, apicem versus incrassatis ; prothorace fortiter transverso, basi in medio profunde foveolata ; 
abdominis segmentis basalibus sat crebre punctatis. 
Long. 2 millim. 
Hab. Guatemaua, Cerro Zunil 4000 to 5000 feet (Champion). 
Third joint of antenne a good deal shorter than the second, fourth rather small, 
fifth to tenth transverse; terminal joint large. Head nearly black. Prothorax very 
strongly transverse, twice as broad as long, with a conspicuous depression in front of 
the scutellum. Elytra greatly longer than the thorax, closely and finely punctate. 
Hind body with the two or three basal segments rather sparingly punctate, the penulti- 
mate segments almost without punctuation. 
This insect is similar to D. sperata, but is of less depressed and less parallel form, 
with the head a little different in shape (the narrowing of it behind not commencing 
so close to the eye), the antenne shorter, and the hind body less closely punctate. 
Only a single individual has been found. 
5. Diestota proxima. | 
Angustula, subparallela, dense punctulata et pubescens, nigra, elytris fuscis ; abdomine rufo, segmentis quarto 
et quinto nigris, apice cum pedibus testaceis ; antennis fere gracilibus, fuscis, articulo basali dilutiore. 
Long. 27 millim. 
Hab. Mexico, Las Vigas (lohr). 
Antenne not elongate, but rather slender; third joint elongate, equal to second ; 
fourth to tenth similar to one another in length, but each slightly broader than its 
predecessor ; the first of these rather longer than broad, the last decidedly transverse ; 
terminal joint elongate. Thorax black, strongly transverse, slightly rounded at the 
sides and but little narrowed behind, very densely punctate. Elytra densely and very 
finely punctate. Hind body with the basal segments closely and distinctly punctate, 
the sixth segment nearly impunctate. 
In the male the seventh dorsal plate of the hind body has in the middle four parallel 
slender teeth, and at each outside another tooth, which differs only very slightly from 
the mesial teeth. 
Although I have seen but a single individual of this species, and although it is 
extremely similar to the variable D. sperata, I have no doubt that D. proxima is 
distinct. The thorax of D. proxima is less transverse, and is black in colour, and the 
fourth joint of the antenne is more elongate.
