CISTELIDA. 
HOMOTRYSIS. 
H. arida, sp. nov. Fem. Sat elongata; leviter ovata ; minus 
convexa ; nitida; pilis elongatis erectis sat crebre vestita ; 
rufobrunnea, capite postice prothoraceque picescentibus, an- 
tennis palpis pedibus labro (et clypeo antice), rufo-testaceis ; 
capite (cum prothorace) dupliciter (subtiliter et sat fortiter) 
sat crebre confuse punctulato ; oculis minus convexis dis- 
tantibus (spatio intermedio quam antennarum articuli 3' 
longitudo sat latiori); prothorace quam longiori parum 
latiori, haud canaliculato (disco utrinque vix impresso), 
antice modice angustato, lateribus leviter sat sequaliter 
(superne visis) arcuatis, basi sinuatim truncata, angulis pos- 
ticis obtuse rectis (superne visis obtusis); scutello punctu- 
lato, in medio leviter carinato ; elytris sat fortiter striatis, 
striis punctulatis (puncturis antice magnis quadratis, re- 
trorsum gradatim obsoletescentibus), interstitiis sat planis 
fortius minus crebre punctulatis; antennis quam corporis 
dimidium paullo brevioribus, articulo 3° quam 4*° manifeste 
longiori ; segmento ventrali apicali zequali, postice rotundato- 
truncato. lLong., 54 1.; lat., 21. 
The principal characters of this species,—among its congeners 
with longish erect pilosity clothing the upper surface,—lie in its 
feebly convex eyes, exceptionally elongate prothorax, nearly uni- 
formly colored upper surface, and elytra with both striz (these 
however only in front) and interstices conspicuously punctulate.

fH. sitiens, sp. nov. Fem. Precedenti affinis ; tota picea, labro 
antennis pedibusque paullo dilutioribus; capite (clypeo 
excepto) sparsim subtilius punctulato; prothorace quam 
longiori fere dimidia parte latiori, ad latera sat fortiter 
rotundato, minus fortiter punctulato, in disco (exempli 
typici) haud impresso, antice vix angustato, angulis posticis 
magis rotundatis; scutello medio nullo modo carinato ; an- 
tennarum subtiliorum magis elongatarum articulo 3° quam 
4"° magis longiori; cetera ut precedentis (H. aride). Long., 
5 1.5 lat. 131 
Closely allied to H. arida, but differing from it by well 
defined characters,—especially by its antenne and legs of dark 
color, the third joint of its antennz longer in proportion to the 
fourth, its prothorax much more transverse and otherwise dif- 
ferently shaped, &c.
