Genus Hydaticus. 213 
Parallel in form, like ruficollis, Fab., though much narrower 
than that insect: the species before us is remarkable also by its 
broadly flavous or testaceous thorax combined with the uniform 
blackness of the elytra, relieved only by the broad and evenly- 
disposed flavous margination, which extends from the humeral 
angles nearly to the apex. 
I obtained a single example some years ago in the Gory Col- 
lection, from China, ; 
6. H. verecundus, n. sp. 
Ovalis. parallelus, punctato-striatus, nitidus, niger, flavo-notatus; 
capite flavo, ad basin transversé nigro, inter oculos macule duz 
flave triangulares, sese attingentes, apparent; thorace brevi, 
lateribus rotundatis, anticé transversé tenuiter depresso, 
flavo, marginibus antico posticoque laté nigris (margo anterior, 
latitudine zequalis, haud latera attinet; margo basalis, ad 
medium anteriore latior, sensim angustior fit, et tenuis latera 
pertingit) ; scutello triangulari, nigro; elytris sat parellelis 
(pone medium sublatioribus), apice rotundato, haud at- 
tenuato; punctorum tres series undique apparent, puncta 
distantia, minime profunda, attamen perspicua et in seriebus 
anda et 3!* minus obsoleta; quoad colorem elytra nigra ap- 
parent; vitta basalis a scutello ad humeros extendit, haud 
basin attingens, tenuis, equalis, recta (aut sub-circularis et 
ad marginem medium leviter sese flectens), ad vittae terminum 
margo usque ad humerum laté flavescit ; pone medium inter 
seriem punctorum 3*” et marginem macula flava apparet, sub- 
quadrata aut aliquando in duas divisa; ad apicem quoque altera, 
major, figura et statura incerta (nunc macula insularis ad ipsum 
marginem, nunc vitta transversalis, inzequalis, communis, lata, 
et ad apicem ipsum pertingens) ; corpore subtus nigro-fusco ; 
antennis flavis ; pedibus flavis, posticis fuscis et flavo-annulatis. 
Long. corp. lin. 4; lat. lin. 24. 
One of the smallest species of the genus; and to be also re- 
cognised by its more than usually distinct punctuation, as well as 
by the pale regular transverse band on its black elytra. It is 
nearly allied to a species in my collection, “ basalis, Dej.,” from 
North America, but much smaller. Iam sorry to say that the 
two examples in my possession forbid me to register the habitat 
of this insect with certainty: one of them is labelled South 
America, the other (from the Gehin Collection) Java.
