DESMOPACHRIA. 17 
fusca; prothorace basi elytrisque versus suturam crebre subtiliter punctatis; corpore subtus levigato, 
impunctato. 
Long. 14, lat. 3 lin. 
Hab. Mexico, Cordova (Hége); Guatemaa, San Geronimo (Champion). 
The head is sparingly and quite finely punctured ; the clypeal margin is very distinct. 
The punctuation on the wing-cases is quite distinct and definite about the suture, but 
disappears entirely at the lateral margins. The species is allied to D. levis, Sharp; and, 
as in that insect, the prosternal process takes two different forms according to the sex ; 
the individuals with the process furcate are, I believe, the males. 
2. Desmopachria dispar. 
Brevis, lata, subrotundata, nitida, capite thoraceque fusco-rufis, hoc lateribus dilutioribus, elytris testaceis dorso 
fusco suffusis, antennis pedibusque testaceis, abdomine pectoreque nigris ; prothorace subtiliter punctato, in 
~ medio fere levigato; elytris crebre subtiliter punctatis, punctis versus latera obsoletis; corpore subtus 
levigato, impunctato. 
Long. 13, lat. 3 lin. 
Hab. Mexico, Cordova and Jalapa (Hége), Guanajuato (Dugeés, coll. Sallé). 
The head is finely but quite distinctly punctate, broadly truncate in front, with the 
clypeal margin very distinct, especially in the middle; the prothorax is finely punc- 
tulate; but the punctures on the middle are very fine indeed; the punctuation of the 
wing-cases is fine, but distinct, and becomes altogether obsolete at the sides; there is an 
indistinct sutural impression which can scarcely be called a stria. 
Although very closely allied to D. variegata, this is, no doubt, a distinct species; the 
colour is less bright, the punctuation a little different, the head more broadly truncate 
in front, and the colour of the under surface is black. The prosternal process assumes 
two forms, as in D. variegata. 
3. Desmopachria portmanni. 
Hydroporus portmanni, Clk. Ann. & Mag. Nat. Hist. ser. 3, x. p. 174. 
Hab. Mexico (Truqut). 
The type of this species in Mr. Fry’s collection is a Desmopachria allied to D. dispar, 
but black beneath ; the cox are impunctate. 
4. Desmopachria polita. 
Brevis, lata, subrotundata, pernitida, fusco-testacea, antennis pedibusque anticis testaceis, pedibus posticis 
rufis, pectore abdomineque nigris, hoc apice rufescente; corpore fere impunctato, superne tantum sparsim 
obsoleteque punctato. 
Long. 3, lat. 2 lin. 
Hab. Mexico, Cordova (Hége). 
The head is nearly rounded in front, being only very obscurely truncate in the
