elytra, which however are so similar in the two that I am inclined to think them 
one species.

95. Laccophilus fusculus, n.sp.—Ovalis, minus latus et depressus, nitidus, testaceus, 
elytris fere impunctatis, fusco-irroratis, maaculis paucioribus minus distinctis ; vertice 
capitis prothoracisque disco obscurioribus ; coxis posterioribus fuscis. Long. 54, 
lat. 3 m.m. 
Though I have seen only a single female of this species I think it distinct ; it is 
very much narrower than Laccophilus decipiens, and appears intermediate between 
it and L. atristernalis Crotch. 
North America; Nevada. 531. 
96. Laccophilus pictus, Cast. M.C.—Ovalis, latiusculus, minus depressus, sat 
nitidus, rufo-testaceus, capite thoraceque testaceis, illo vertice, hoc basi in medio 
nigris ; elytris fere impunctatis, nigris, maculis irregularibus numerosis testaceis. 
Long. 5, lat. 3 m.m. 
In the male of this species the marks forming the coxal file are not quite so deep 
and distinct as they are in Dytiscus maculosus (No. 92): in the female the external 
edge of the elytra is dilated at a little distance before the apex, but this is also 
seen in some individuals of the same sex of Dytiscus maculosus. 
Mexico ; Guatemala, (San Geronimo, Champion). 532. 
97. Laccophilus insignis, n. sp.—Ovalis, minus depressus, sat nitidus, rufo-testaceus, 
capite thoraceque testaceis, illo vertice hoc basi im medio nigris; elytris fere 
impunctatis, nigris, fasciis duabus transversis maxime irrecularibus, maculisque 
versus apicem testaceis. Long. 52, lat. 34 m.m. 
Closely allied to Laccophilus pictus, but Jarger and of more elongate form, and 
with the yellow marks on the elytra more extensive, so that a very irregular basal 
and a medial fascia is formed by them. ‘The tarsi of the male are thicker, and the 
marks forming the coxal file in the same sex are coarser and more conspicuous. 
North America, Texas ; (Lower California fide Crotch). 533. 
98. Laccophilus fasciatus, Aubé, M.C.—Ovalis, depressiusculus, sat nitidus, 
testaceus, elytris impunctatis, minus distincte fusco-irroratis, maculis lateralibus et 
apice testaceis, fascia lata ante apicem nigra; prothorace basi in medio breviter 
lobato ; pectore seepe infuscato. Long. vix 5, lat. 25 m.m.
